Answer: See explanation

Step-by-step explanation:

7.) 2 (x - 1) = 45

2x - 2 = 45

Add 2 to both sides

2x = 47

x = 23.5

8.) 5x - 2 = 2 (4)

5x - 2 = 8

Add 2 to both sides

5x = 10

Divide both sides by 5

x = 2

9.) x = 2 (30)

x = 60

10.) 3x - 6 = 2 (x)

3x - 6 = 2x

Add 6 to both sides

3x = 2x + 6

Subtract 2x from both sides

3x - 2x = 6

x = 6

2x + 1

Substitute x for 6

2 (6) + 1

12 + 1 = 13

2y = 13

Divide both sides by 2

y = 6.5

Hope that helped!

What is 2c+2=8 ? Thanks for your help if you put the answer lol

Juliette [100K]

C= 3 because you subtract 2 on both sides, which is 2c= 6 then you divide 2 on both sides to get c= 3 haha

- 8 / 20 = y / - 4

y = - 4 × - 8 / 20

y = 4 × 8 / 4 × 5

y = 8 / 5

What is the equation in slope-intercept form of the line that passes through the points (0, −4) and (2, 0)?

Nastasia [14]

Answer:

$y = 2x -4$

Step-by-step explanation:

Slope intercept form is $y = mx + b$ where m is the slope and b is the y-intercept.

Slope is $\frac{rise}{run}$ or $\frac{y_2 - y_1}{x_2-x_1}$ in this case = $\frac{0 - (-4)}{2 - 0} = \frac{4}{2} = 2$

Substitute one of the coordinates for x and y. I am going to use (0, -4) so:

$-4 = 2(0) + b\\-4 = 0 + b\\-4 = b$

since m = 2 and b = -4, we can conclude that the equation would be

$y = 2x -4$
