thae answer is something true
Answer:
x=-2, y=-3
Step-by-step explanation:
we can rearrange the questions to make it easier
y=3x+3
2y=-3x-12
if you add the two equations, you get
3y=0x-9
so y=-9/3 = -3
plug y into one of the equations
-3=3x+3
-6=3x
x=-2
and then check your work by plugging into the other equation:
2*-3=-3(-2)-12
-6=6-12
-6=-6
Answer:

Step-by-step explanation:
Given

Transformation: 180 degrees clockwise around the origin
Required
Determine the new coordinates Z'
<em>When a point (x,y) is rotated 180 degrees clockwise around the origin, the new point is: (-x,-y)</em>
<em></em>
So:

Then:

4 + 5 = 9
180 ÷ 9 = 20
Sand = 20×4 = 80
Cement = 20×5 = 100
