The graph of an equation with a negative discriminant always has which characteristic?
Answer:
The graph does not intercept the x-axis
Step-by-step explanation:
Hi there!
When the discriminant is positive, it means that in the quadratic equation, you can take the square root of this number and end up with two distinct solutions, one negative and one positive. The graph will intercept the x-axis twice.
When the discriminant is zero, it means that you won't be taking the square root of any number in the quadratic equation and you'll end up with two solutions that are equal, or just one distinct solution. The graph will intercept the x-axis once.
When the discriminant is negative, it means that the quadratic has no real solutions, meaning that it does not intercept the x-axis. It is impossible to take the square root of a negative number.

In Sean's class there are 13 boys and 16 girls. Sean will randomly pull one of their names out of a hat to give
a presentation to the class. Which of the following is the probability the student picked will be a girl?
(1) 0.45
(3) 0.62
(2) 0.55
(4) 0.81
Answer:
0.62
Step-by-step explanation:
it is because the number of girls in the class is larger than the number of boys in the class which means the probability is high
The probability of picking a girl is 0.55.
What is probability?'Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.'
According to the given problem,
Number of boys = 13
Number of girls = 16
Total number of students = 13 + 16
= 29
Probability = [tex]\frac{Favorable events}{Total number of events}[/tex]
= [tex]\frac{16}{29}[/tex]
= 0.55
Hence, we can conclude, the probability of picking a girl is 0.55.

What is the average rate of change of the function f(x)=2x^2+x+5 over the interval -2<x<2?
A. -4
B. -1
C. 1
D. 4
Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 2, 2 ] , then
f(b) = f(2) = 2(2)² + 2 + 5 = 8 + 2 + 5 = 15
f(a) = f(- 2) = 2(- 2)² + (- 2) + 5 = 8 - 2 + 5 = 11 , then
average rate of change = [tex]\frac{15-11}{2-(-2)}[/tex] = [tex]\frac{4}{4}[/tex] = 1 → C
Solve the equation 5x - 10 = 25
please tell me the working
Answer:
x = 7
Step-by-step explanation:
5x - 10 = 25
shift -10 to the other side then -10 become plus 10
5x = 25 + 10
now do addition in right hand side
5x = 35
shift 5 to right hand side . 5 divides 35 because in multiplication when u shift number or variables to other side it changes to division)
x = 35/5
x = 7
The solution to the equation 5x - 10 = 25 is x = 7.
To solve the equation 5x - 10 = 25, we want to isolate the variable 'x' on one side of the equation.
First, we can start by getting rid of the constant term on the left side of the equation. We do this by adding 10 to both sides:
5x - 10 + 10 = 25 + 10
This simplifies to:
5x = 35
Next, we want to isolate 'x' by dividing both sides of the equation by the coefficient of 'x', which is 5:
5x/5 = 35/5
This yields:
x = 7
Therefore, the solution to the equation 5x - 10 = 25 is x = 7. We can verify this by substituting x = 7 back into the original equation:
5(7) - 10 = 25
35 - 10 = 25
25 = 25
Since the equation holds true, we can conclude that x = 7 is the solution.

If the equation of a line is 2y+3x=3, what is the x intercept of the line? HELP MEEE PLEASE
Answer:
the anwers is b= 3/2 And yeah that's you're anwers
Answer:
(1,0)
Step-by-step explanation:
Hi there!
We're given the equation of the line as 2y+3x=3, and we want to find the x intercept of the line.
The x intercept is the coordinate point at which the line passes through the x axis. Therefore, the value of y at the x intercept will be 0.
So we can substitute 0 as y in 2y+3x=3; we'll only have x left if we do this to solve for the x intercept.
2(0)+3x=3
multiply
3x=3
divide both sides by 3
x=1
so the x intercept is 1; as a point it's (1,0)

Elizabeth sells popcorn to the students at the annual school dance. She pays $30.00 to rent the popcorn maker and $0.75 in supplies for each bag of popcorn. If Elizabeth buys supplies for p bags of popcorn, which equation expresses her total cost, c, in dollars?
Answer:
c = $30 + $0.75p
Step-by-step explanation:
total cost = total fixed cost + total variable cost
total fixed cost = $30
Fixed costs are costs that do not vary with output.
total variable cost = variable cost per unit x total unit
p x 0.75
Variable costs are costs that vary with production

Each figure shows a triangle with one of its angle bisectors.
12) 22 - 38°. Find mZTRS.
Answer:
76 degrees
Step-by-step explanation:
this special line is an angle bisected.
that means it splits the angle at its starting point in 2 halves. as these names indicate, both parts are of equal size (half of the general angle).
we know one part (2) of this split angle : 38 degrees.
the other part (1) had to be equally sized : 38 degrees.
so, the total angle at point R is the sum of both split angles:
TRS = 38+38 = 76 degrees.
Find the equation of a line that is parallel to y = 5x + 1 and passes through the point (3, -4).
Give your answer in the form y = mx + b.
Given:
The equation of a line is:
[tex]y=5x+1[/tex]
A line is parallel to the given line and passes through the point (3,-4).
To find:
The equation of the line in the slope intercept form.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept of the line.
We have,
[tex]y=5x+1[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=5[/tex]
Slope of the given line is 5.
We know that the slopes of parallel lines are equal. So, the slope of the required line is 5.
The required line passes through the point (3,-4) with slope 5. So, the equation of the required line is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(-4)=5(x-3)[/tex]
[tex]y+4=5(x)+5(-3)[/tex]
[tex]y+4=5x-15[/tex]
Subtracting 4 from both sides, we get
[tex]y+4-4=5x-15-4[/tex]
[tex]y=5x-19[/tex]
Therefore, the equation of the required line is [tex]y=5x-19[/tex].

Step-by-step explanation:
Given
[tex]f(x) = x^2[/tex]
Required
Determine g(x)
f(x) represents the parent function. And from the graph, we have:
[tex]f(x) = x^2[/tex]
f(x) is first shifted 2 units right.
The rule is:
[tex]f'(x) = f(x - 2)[/tex]
So, we have:
[tex]f'(x) = (x - 2)^2[/tex]
Next, f'(x) is shifted 1 unit up to give g(x), the blue graph.
The rule to this is:
[tex]g(x) = f'(x) + 1[/tex]
[tex]g(x) = (x - 2)^2 + 1[/tex]

The function f(x) = x³ after translation becomes g(x) = x³ - 4.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of function as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is the function f(x) = x³ and its transformed graph as shown in the image.
The function f(x) is translated downwards. This is called downward translation. Assume that the function f(x) after the translation becomes g(x). The function f(x) = x³ passes through the origin. After translation, all the {y} - coordinates will be shifted in the downward direction by 4 units. So, we can write the final function as -
g(x) = f(x) - 4
g(x) = x³ - 4
Therefore, the function f(x) = x³ after translation becomes g(x) = x³ - 4.
