neonofarm [45]

Answer:

Step-by-step explanation:

The leftmost line segment has a slope of -2 and (-1,-1)  is a point on the line.

Equation: y = -2x-3

middle line segment has a slope of 0 and  y-intercept of -2.

Equation:  y = -2

The rightmost line segment has a slope of 1.5. (5,0) is a point on the line.

y = 1.5(x-5) = 1.5x-7.5

Solve the equation. Check the solution.<br> 9-17x-5-4x=7
Shalnov [3]

Answer:

x = -1/7

Step-by-step explanation:

Solve for x

9-17x-5-4x=7

Combine like terms

-21x +4 = 7

Subtract 4 from each side

-21x-4+4 = 7-4

-21x = 3

Divide each side by -21

-21x/-21 = 3/-21

x = -1/7

Check

9 - 17(-1/7) -5 -4(-1/7) =7

9 + 17/7 -5 + 4/7 =7

4 +21/7 = 7

4+3 = 7

7=7
