- 7x + 3y =- 24
2x - 4y =- 12

Answer: x = 6

Step-by-step explanation:

m<CAD = m<BAC

m<CAD = 4x

m<CAD + m<BAC = m<BAD

4x + 4x = 10x - 12

8x = 10x - 12

-10x -10x

-2x = -12

x = -12/-2

x = 6

Answer:

Option 2

Step-by-step explanation:

Step 1: Translate

"a number" = x

"product" means multiply

"-2/3" = -2/3

"is" means equal

"-9/10" = -9/10

Step 2: Set up equation

-2/3x = -9/10

Step 3: Solve for x

Answer:

The answer is the first choice and the last choice.

Step-by-step explanation:

The first one is already solved for y, so when you plug 9 into the equation in the x spot since 9 is the x-coordinate of the point, you get -2, which is correct because it is the corresponding y-value.

The second one is a mess when trying to solve and it clearly doesn't yield the right answer.

For the last one, when you solve for y and then plug in 9 for x, you get -2, the y-value making it correct.

The answer would be 'C'

Answer:

Step-by-step explanation:

let y be the total charges

given that the hour is h

and the cost for raw material is r

therefore

1. The first hour of service call = $60

2. For each additional hour= 25h

 3. 30% over the cost of the materials.= 30/100*r=0.3r

total charges

y=60+25h+0.3r

therefore the expression is

y=60+25h+0.3r

Answer:

24

Step-by-step explanation:

40 divided by 5 = 8

Plz mark me brainsliesttttt

============================================

Work Shown:

8/3 = (6+2)/3

8/3 = 6/3 + 2/3

8/3 = 2 + 2/3

8/3 = 2 & 2/3

The whole part is 2. The fractional part is 2/3.

-----------

Another way you could do the problem is to use long division as shown in the diagram below.

The result of the long division is

8/3 = 2 remainder 2

The quotient 2 forms the whole part and the remainder is the numerator of the fractional part 2/3.

So that's another way to get 2 & 2/3

Answer: choice A

Step-by-step explanation:

The linear inequality represented by the graph  is y≥1/3x-1

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Let us find slope of line passing through points (0, -1) and (3, 0)

Slope = 0+1/3

=1/3

y intercept we have to find

0=1/3(3)+b

b=-1

So equation of line is y=1/3x-1

As the shading is away from origin, we use the greater than or equal to symbol.

y≥1/3x-1

Hence, the linear inequality represented by the graph  is y≥1/3x-1

Answer:

the correct answer is the second one

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

When you are trying to find if they are equivalent, you only want to use one value. If they are both positive, it doesn't mean that they are quivalent. They would have to be the same.

Answer:

Ok, so first, at the end of the equation, It says "+ 4" , right? So you put a point on positive 4 on the y-axis (the one that goes up and don, the vertical line.). Then, 2x means that's your slope, but since your graph only goes up to five, you gotta count down ward. So, go down from your point on the y-axis (4) twice and over to the LEFT (<--) once. Plot your point where you end up. then use a straightedge like a ruler, and connect your two points on the graph, and you have your line!

 in this problem we want to find who earns more between Liam and Mathiew

given

Liam earned $1,200 in 2 weeks

Matthew earned $1,450 in 4 weeks

Another way to find out who earns more per week is to find their weekly earns

for Liam earned $1,200 in 2 weeks

in a week he will earn= 1200/2

=$600 per week

for Mathew earned $1,450 in 4 weeks

in a week he will earn= 1450/4

=$362.5 per week

In a week Liam earns more

Answer:

9x² - 42x + 49

Step-by-step explanation:

Given

(3x - 7)² = (3x - 7)(3x - 7)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(3x - 7) - 7(3x - 7) ← distribute both parenthesis

9x² - 21x - 21x + 49 ← collect like terms

= 9x² - 42x + 49

Answer:

95 = x

85 = z

75 = y

Step-by-step explanation:

**remember** all triangles contain 180 degrees

this means that the triangle to the left should add up to 180 to we can set up this equation

180 = 60 + 25 + x

180 = 85 + x

95 = x

now **remember** a flat line is 180 degress so x + z is 180... we can set up this equation:

x + z = 180

plug in x = 95 from before

95 + z = 180

z = 85

**remember** again that a triangle in 180 degrees so for the right one we can set up this equation by pluggging in the z=85

180 = 20 + 85 + y

180 = 105 + y

75 = y

Answer:

first option

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , thus

x = 180° - (60 + 35)° = 180° - 95° = 85°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

z is an exterior angle of the triangle , thus

z = 60° + 35° = 95°

Using the sum of angles in a triangle, then

y = 180° - (95 + 20)° = 180° - 115° = 65°

Thus

x = 85°, y = 65°, z = 95°

Answer:

y = x+5

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   = ( 7-3)/(2 - -2)

   ( 7-3)/(2+2)

   4/4

  1

Then slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 1*x+b

y = x+b

Substitute a point into the equation

7 = 2+b

7-2 =b

5=b
