5x - 3x + 4 = -4 +20
2x + 4 + 16
subtract 4 from each side
2x=12
divide each side by 2
x=6
Answer:
-25
Step-by-step explanation:
-81=7k+19=3k
7k-3k=-19-81
4k=-100
k=-25
Answer:
y = 0.25x - 9.5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 0.25 , then
y = 0.25x + c ← is the partial equation
To find c substitute (6, - 8) into the partial equation
- 8 = 1.5 + c ⇒ c = - 8 - 1.5 = - 9.5
y = 0.25x - 9.5 ← equation of line
