Answer:
B.
Step-by-step explanation:
because y is a rotation that rotates up and down like a ramp!
Answer:
-2.25
Step-by-step explanation:
9(1-x) = 27Y
9-9x =27y
-9x -27y = -9 multiply all terms by -1
9x +27y =9 equation (1)
x-y= -11/2 equation (2)
by solving 2 equations
x= -3.875
y= 1.625
∴ x+ y = 1.625 +(-3.875) = -2.25
19-3=16
16/8=2
2x8+3=19
The answer is 2.
I think the expression that you need is, 4-(2x). Hope it helps!
