Answer:
y=5x-10
Step-by-step explanation:
5x - y = 10
-y = -5x + 10
y = 5x -10

<h3>
Answer: 19</h3>
==============================================================
Explanation:
T is the midpoint of PQ, which means T splits PQ into two equal parts. Those parts being PT and TQ.
Set them equal to each other and solve for x.
PT = TQ
3x+7 = 7x-9
3x-7x = -9-7
-4x = -16
x = -16/(-4)
x = 4
So,
PT = 3x+7 = 3*4+7 = 19
TQ = 7x-9 = 7*4-9 = 19
Both PT and TQ are 19 units long to help confirm the answer.
Answer:
8 vertices
Step-by-step explanation:
Use Euler's Theorem: V-E+F=2
F=12
E=18
Thus, we have:
V-18+12=2
V-18=-10
V=8
So there are 8 vertices
