Answer:
Step-by-step explanation:
- - 9x - 5y = -18
- 4x + 5y = 33
<u>Add up the two equations:</u>
- -9x - 5y + 4x + 5y = -18 + 33
- -5x = 15
- x = -3
<u>Finding y:</u>
- -9*(-3) - 5y = -18
- 27 - 5y = -18
- 5y = 27+18
- 5y = 45
- y = 9
Answer is: (-3, 9)
Answer:
<h2>C: 3 inches by 6 inches</h2>
Step-by-step explanation:
Notice that point A is a mid point. If we cut the prism though that point, perpendicular to the shaded face, it means the side of 4 inches will be divide in two equal parts, and the 3-6 inches face won't be cut.
Therefore, the dimensions of the cross section is 3 inches by 6 inches, which are the dimensions of the face that won't be cut, because they don't intersect with point A.
