discount is 15%.
Answer:
A.Y=3/2x-12
Step-by-step explanation:
Option A would be the correct answer.
Answer:
1)-9
2)16
3)-2
Step-by-step explanation:
1)
-3x + 4 = 31
-3x = 31 - 4
-3x = 27
-x = 27/3
-x = 9
x = -9
2)
2x + -10 = 22
2x = 22 + 10
2x = 32
x = 32/2
x = 16
3)
40 = 32 – 4r
-4r = 40 - 32
-4r = 8
-r = 8/4
-r = 2
r = -2
Answer:
320,000/10=32000
Step-by-step explanation:
Answer:
(17+11)/(-9-5)= 28/-14= -2 the slope
y + 11 = -2(x - 5)
y + 11= -2x + 10
y = -2x - 1 the equation
