Answer:
Expressions for y:
1. A - 3B
3. A/3 - B
3. (27/13, -60/13)
Step-by-step explanation:
Expressions for y:
A - 3B
A/3 - B
Find combinations to eliminate x
A) 8x + y = 12
B) 2x - 3y = 18
Expressions for y:
A - 3B
A/3 - B
y = 12 - 8x
2x - 3(12 - 8x) = 18
2x + 24x - 36 = 18
26x = 54
x = 54/26 = 27/13
y = 12 - 8(27/13) = -60/13

Yes, SSS
PR are already a given side. PS and PQ are also given sides. Lastly, RS and RQ are given sides.
The only that has the shape of the one below.
y = -4(x^3 + 7x^2+8x - 16)
Let x = 1
y = - 4(1 + 7 + 8 - 16)
y = 0
y = -4(x -1)(x^2 + 8x + 16)
y = -4(x - 1)(x + 4)^2
