19) The function C(x) = 25x+75 represents the labor cost (in dollars) for Bob's Auto Repair to replace
your alternator, where x is the number of hours. The table below shows sample labor costs from its main
competitor, Budget Auto Repair. The alternator is estimated to take 5 hours of labor. Which company
would you hire? Explain.
Hours 1,2,3
Cost
$90 $130 $170
we can see that the function C(x) = 25x + 75 represents the labor cost (in dollars) for Bob's Auto Repair to replace your alternator, where x is the number of hours. We can use this function to find the cost of replacing an alternator that is estimated to take 5 hours of labor.
C(5) = 25(5) + 75 = 125 + 75 = 200
We also have the labor cost for the main competitor, Budget Auto Repair, in a table format.
Hours Cost
1 $90
2 $130
3 $170
We can see that the cost of labor increases as the number of hours increases. From the information provided it's hard to say which company would be cheaper to hire, however the company with the function C(x) = 25x + 75 would be cheaper if the alternator takes more than 4 hours of labor, otherwise Budget Auto Repair would be cheaper.
It's important to check the warranty, prices of parts, and reputation of both companies. If a company has a good reputation and a good warranty, it may be worth paying a little more for labor.
It's also a good idea to get a second opinion or ask for a quote from both companies before making a decision.
In conclusion, it's hard to say which company would be cheaper to hire based on the information provided, but it's recommended to check the warranty, prices of parts, and reputation of both companies, and to get a second opinion or quote from both companies before making a decision.

Step-by-step explanation:
Given Equations:y = 6x - 9 ---------------(1)
y = 2x + 3 --------------(2)
Coordinate point:(x, y) = (3, 9)So,
x = 3, y = 9
Put this in Eq. (1) to verify.
9 = 6(3) - 9
9 = 18 - 9
9 = 9 [Equation satisfied]
Now, put x = 3, y = 9 in Eq. (2)
9 = 2(3) + 3
9 = 6 + 3
9 = 9 [Equation satisfied]
Since, both the equations are satisfied by the values of x and y, we can say that x = 3 and y = 9 is the solution to the system.

What would you make the size of the hypotenuse of a right tria gle to make if its other two size measure 2 and 5 cm?
a. 7 squared.
b. 29 squared.
C. 29.
d. 29 squared by 3.
Answer: To find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides (the legs).
So, if the legs of the right triangle measure 2 cm and 5 cm, the hypotenuse c can be calculated as follows:
c² = a² + b²
c² = 2² + 5²
c² = 4 + 25
c² = 29
Therefore, the length of the hypotenuse c is the square root of 29.
c = √29
The answer is c = √29 which is the only one that is not squared, So the answer is (C) 29.

Given the function h(x)=-x²+4x+12, determine the average rate of change of the function over the interval -1≤x≤8
The average rate of change of the function over the interval -1≤x≤8 is -3.22.
How do you determine the average rate?The average rate of change of a function over an interval is given by the formula (f(b) - f(a)) / (b - a) where f(x) is the function, a is the starting point of the interval, and b is the ending point of the interval.
In this case, the function is h(x) = -x² + 4x + 12, the interval is -1≤x≤8.
Plugging in the values we have:
Average rate of change = (h(8) - h(-1)) / (8 - (-1)) = (h(8) - h(-1)) / 9
h(8) = -8² + 4(8) + 12 = -64 + 32 + 12 = -20
h(-1) = -1² + 4(-1) + 12 = 1 - 4 + 12 = 9

Find the measure of each missing angle.
The measures of the missing angles are given as follows:
m < 1 = 4º. m < 2 = 88º.m < 3 = 124º.m < 4 = 88º.m < 5 = 36ºHow to obtain the angle measures?First we consider that when two angles form a ray, they are supplementary, meaning that the sum of their measures is of 180º.
Then the measures of angles 3 and 5 are given as follows:
m < 3 + 56 = 180 -> m < 3 = 124º.m < 5 + 144 = 180 -> m < 5 = 36º.The sum of the internal angles of triangle is of:
S(3) = (3 - 2) x 180º = 180º.
Hence the measure of angle 4 is obtained as follows:
m < 4 + 36 + 56 = 180
m < 4 = 180 - (36 + 56)
m < 4 = 88º.
Angles 2 and 4 are congruent, hence the measure of angle 2 is given as follows:
m < 2 = m < 4 = 88º.
The sum of the internal angles of a quadrilateral is of:
S(4) = (4 - 2) x 180º = 360º.
Hence the measure of angle 1 is obtained as follows:
m < 1 + 88 + 144 + 124 = 360
m < 1 = 360 - (88 + 144 + 124)
m < 1 = 4º.

The linear equation for the relationship between the weight and number of months is y = 5.55x + 78.95.
First-order equations include linear equations. In the coordinate system, linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., just one variable). Multiple variables may be present in a linear equation. Linear equations with two variables, for example, are used when a linear equation contains two variables.
We know that the sumo wrestler's weight is 140 kilograms after 11 months and he gained weight at a rate of 5.55 kilograms per month.
The equation for the relationship between the weight and number of months can be represented as:
y = 5.55x + b
Where y is the sumo wrestler's weight (in kilogram) after x month, 5.55 is the rate at which he gained weight per month, x is the number of months and b is the y-intercept.
To find the value of b, we can use the point (11, 140) which represents that after 11 months the sumo wrestler's weight is 140 kg, and substitute it into the equation:
y = 5.55x + b
140 = 5.55(11) + b
Solving for b:
b = 140 - (5.55 * 11)
b = 140 - 61.05
b = 78.95
So the complete equation is:
y = 5.55x + 78.95
Where y is the sumo wrestler's weight (in kilogram) after x months.
Therefore, The linear equation for the relationship between the weight and number of months is y = 5.55x + 78.95.

What are linear inequalities?
Inequality represents the mathematical expression in which both sides are not equal. If the relationship makes the non-equal comparison between two expressions or two numbers, then it is known as inequality in Maths. In this case, the equal sign “=” in the expression is replaced by any of the inequality symbols such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤) or not equal to symbol (≠). The different types of inequalities in Maths are polynomial inequality, rational inequality, absolute value inequality.
The symbols ‘<‘ and ‘>’ express the strict inequalities and the symbols ‘≤’ and ‘≥’ denote slack inequalities. A linear inequality seems exactly like a linear equation but there is a change in the symbol that relates two expressions.
e.g. y>x+2
Now,
Given charge of $70 per delivery and A charge of 6.5% of the total value of the freight for each delivery and least amount is $102,000.
Let only one delivery is possible per day and no. of deliveries=n
amount of each freight=x
Therefore,
Linear inequality will be n(6.5/100**x+70)>102000
So least values of n and x will be
n=30 and x=$60000
Hence,
number of least deliveries is 30 and value of freight is $60000.

MODELING WITH MATHEMATICS: The function f(t)=-16t^2+10 models the height (in feet) of an object t seconds after it is dropped from a height of 10 feet on Earth. The same object dropped from the same height on the moon is modeled by g(t)=-8/3t^2+10.
Describe the transformation of the graph of f to obtain g.
The graph of g is a horizontal stretch by a factor of (blank) of the graph of f. Round your answer to the nearest hundredth.
From what height must the object be dropped on the moon so it hits the ground at the same time as on Earth? Round your answer to the nearest hundredth.
The object must be dropped from a height of (blank) feet.
The transformation of the graph of f to obtain g is described as follows:
The graph of g is a vertical compression of the graph of f by a factor of 6 units.
The object must be dropped at a height of 1.66 feet from the moon so it hits the ground at the same time as on Earth,
What is the transformation?The functions in the context of this problem are given as follows:
f(t) = -16t² + 10.g(t) = -8/3t² + 10.The multiplier that was applied to function f(t) to obtain function g(t) is given as follows:
-16x = -8/3
16x = 8/3.
x = 8/48
x = 1/6.
The leading coefficient was divided by 6, meaning that the graph of g is a vertical compression of the graph of f by a factor of 6 units.
When does the object hits the ground?The object hits the ground when the output of the quadratic function assumes a value of zero.
For the Earth, we have that the time to hit the ground is obtained as follows:
-16t² + 10 = 0
16t² = 10
t² = 5/8
[tex]t = \sqrt{\frac{5}{8}}[/tex]
t = 0.79 seconds.
For the Moon, the function is given as follows:
g(t) = -8/3t² + h.
In which h is the initial height.
We want that g(t) = 0 when t = 0.79, hence the initial height is obtained as follows:
0 = -8/3(0.79)² + h

What is the solution set of the following equation 8x x 15 7x 12 Ã {} all reals?
The solution set of the following equation (- 8x + x + 15) = ( - 7x + 12) is zero i.e this equation does not have any solution.
Equation is (- 8x + x + 15) = (-7x + 12)
Now solving
(-8x + x + 7x ) = ( 12 - 15 )
( - 7x +7x) = (-3)
( 0 )= ( - 3)
Since 0 = -3 is not correct, therefore, the equation does not have any solution.
So it is stated that the equation (- 8x + x + 15) = ( - 7x + 12) does not have any solution in its solution set.
