Answer:
No
Step-by-step explanation:
-18:8 can be simplified to 9:4
-20:14 can be simplified to 10:7
-9:4 does not equal 10:7

Answer:
No. Steven is not correct.
Step-by-step explanation:
The area of shape A is 15 (either multiply 5 x 3 or just count squares). The area of shape B is 9.
15 is not double 9.
k=-6/7 solved by cross multiplying.
Answer:
x=0, y=-2
Step-by-step explanation:
Because 9y appears twice in both equations, you can subtract the equations to eliminate the y variable so you can solve for x:
-7x + 9y = -18
-(4x + 9y = -18)
__________
-11x = 0
x = 0
Since we know x=0, then we plug it back into one of the equations to get the value of y:
-7x + 9y = -18
-7(0) + 9y = -18
0 + 9y = -18
9y = -18
y = -2
Therefore, x=0, and y=-2
