Answer:
x = -6
Step-by-step explanation:
-1.5x = 9 Divide the -1.5 on both sides
x = -6
Plug in the answer to make sure it works.
-1.5(6) = 9
9 = 9
Answer:
Option B
Step-by-step explanation:
Given that the regression equation using least squares for test scores and student teacher ratio is
Test Score = 557.8 + 36.42 In (Income).
Say if 1% income is increased.
Let income be 100
New income = 101
Then we have
Test score original =

Test score new income
= 
Increase = 0.362~0.36
Option B is right.
Leave the slope alone in the y=mx+b equation but solve for b by plugging in your point
y=3/4x-12
Answer: x=32
Exclamation:
-3x\4+25=1/8x-3
-3/4x+25=x/8-3
-6x+200=x-24
200=x-24+6x
200=7x-24
200+24=7x
224=7x
224/7=32
