Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses

b. 2x - 7 and the opposite of 2x

Step-by-step explanation:

-20 > -2x + 4

2x > 4 + 20

2x > 24

x > 12

or

x ∈ 《12 , + ∞》

-20 > -2x + 4

-20 -4 > -2x

-24 > -2x

-24/-2 < x  <inequality changes when you divide by a -ve no. >

12 < x

Answer:

3) 5/2

Step-by-step explanation:

5x - 2y = 20

(First, put it in slope intercept form: y = mx + b).

5x - 2y - 5x = 20 - 5x --> Subtracted 5x on both sides of the equation

- 2y  = -5x + 20 --> Simplified

-2y/-2 = (-5x + 20)/-2 --> Divided by -2 on both sides

y = 2.5x - 10 --> Simplified

Since formula is, y = mx + b, then:

m (slope): 2.5

b (y-intercept): -10

Therefore, the answer is 3) 5/2

Hope this helped! <3

Let's solve for y.

5x − 2y = 20

Step 1: Add -5x to both sides.

5x−2y+−5x=20+−5x

−2y=−5x+20

Step 2: Divide both sides by -2.

−2y/−2  =  −5x + 20/−2

y =  5/2x − 10

Answer:

y =  5/2x − 10

Slope = x, therefore, the slope = 5/2.

Step-by-step explanation:

7x^2+10x-3=x^2+3x

7x^2+10x-3-x^2-3x=0

6x^2+7x-3=0

6x^2+9x-2x-3=0

3x x (2x+3)-(2x+3)=0

(2x+3)x(3x-1)=0

2x+3=0

3x-1=0

x1=- 3/2

x2= 1/3

Answer:

21 dollars

Step-by-step explanation:

Answer:

$21

Step-by-step explanation:

Make the original statement into a ratio.

$28/4

Simplify the fraction above.

$28/4 = 7

So, you earn $7 per car you wash.

As a result, you multiply $7 by the number of cars the question is asking you for. In this case it is 3 cars.

So, you multiply 7 x 3

7 x 3 = 21

Therefore, you will earn $21 for washing 3 cars.

Step-by-step explanation:

Given:

Consider the rule of translation of a triangle is [tex]T_{(-3,5)}(x,y)[/tex].

To find:

The another way to write this rule.

Solution:

We have, the rule of translation [tex]T_{(-3,5)}(x,y)[/tex].

We know that [tex]T_{(a,b)}(x,y)[/tex] is defined as

[tex](x,y)\to (x+a,y+b)[/tex]

So, [tex]T_{(-3,5)}(x,y)[/tex] can be defined as

[tex](x,y)\to (x+(-3),y+(5))[/tex]

[tex](x,y)\to (x-3,y+5)[/tex]

It means, the triangle is translated 3 units left and 5 units up.

Therefore, the correct option is A.

Answer:

A

Step-by-step explanation:

Answer:

4x + y = -12

Step-by-step explanation:

Standard form is Ax + By = C

First, distribute the -4:

у + 4 = -4(х + 2)

y + 4 = -4x - 8

Subtract 4 from both sides:

y = -4x - 12

Add 4x to both sides:

4x + y = -12

So, the standard form equation is 4x + y = -12

Answer:

X=15

Explanation: You have no like terms to combine and are at the last step of the algebraic equation. So, you would divide 7 on both sides. 7 by 7 cancels it out and 105 divided by 7 equals 15. Hope this helps ^-^.

The solution to the equation 7x = 105 is x = 15.

We have the equation: 7x= 105

To solve for x in the equation 7x = 105, we need to isolate x on one side of the equation.

Divide both sides of the equation by 7:

(7x)/7 = 105/7

Simplifying:

x = 15

Therefore, the solution to the equation 7x = 105 is x = 15.

Answer:

Unitary cost per card= $0.21

Step-by-step explanation:

Giving the following information:

Number of cards per packecge= 25

Total cost per package= $5.25

To calculate the unitary cost of each card, we need to use the following formula:

Unitary cost per card= total cost / number of cards per package

Unitary cost per card= 5.25 / 25

Answer:

f=gx−3/x−5

Step-by-step explanation:

Step 1: Flip the equation.

fx−5f+3=gx

Step 2: Add -3 to both sides.

fx−5f+3+−3=gx+−3

fx−5f=gx−3

Step 3: Factor out variable f.

f(x−5)=gx−3

Step 4: Divide both sides by x-5.

f(x−5)/x−5=gx−3/x−5

Formula to find slope is (y2-y1) / (x2-x1)

Here we have 4 points to choose from, but we only need 2. I will use the first 2 points.

The y2 is 7, the y1 is 14, the x2 is 3, the x1 is 2.

Substitute these numbers into the formula.

(7-14) / (3-2)

Answer:

Step-by-step explanation:

For number 1.

If x = -2.

                    y = 4x + 3 = 4(-2) + 3 = -8 + 3 = -5

If x = 3

                    y = 4x + 3 = 4(3) + 3 = 12 + 3 = 15

If x = -4

                   y = 4x + 3 = 4(-4) + 3 = -16 + 3 = -13

If x = -5

                  y = 4x + 3 = 4(-5) + 3 = -20 + 3 = -17

If x = 5

                  y = 4(x) + 3 = 4(5) + 3 = 20 + 3 = 23

For number 2.

If x = -2

                 [tex]y = x^{2} + 4 + 2x = (-2)^{2} + 4 + 2(-2) = 4 + 4 - 4 = 4[/tex]

If x = 3

                [tex]y = x^{2} + 4 + 2x = (3)^{2} + 4 + 2(3) = 9 + 4 + 6 = 19[/tex]

If x = -3

                [tex]y = x^{2} + 4 + 2x = (-3)^{2} + 4 + 2(-3) = 9 + 4 - 6 = 7[/tex]

If x = 4

               [tex]y = x^{2} + 4 + 2x = (4)^{2} + 4 + 2(4) = 16 + 4 + 8 = 28[/tex]

If x = -4

               [tex]y = x^{2} + 4 + 2x = (-4)^{2} + 4 + 2(-4) = 16 + 4 -8 = 12[/tex]
