The system of equations:2 y = - x - 12 y = x + 5---------------------- x - 1 = x + 5- 2 x = 5 + 1- 2 x = 6x = - 6 : 2x = - 32 y = - 3 + 52 y = 2y = 1The solution is ( - 3 , 1 ).Answer: The x-coordinate of the solution to the system is: x = - 3.

Answer:
3/2
Step-by-step explanation:
slope=rise/run=30/20=3/2
Y = abˣ
(a ≠ 0, b ≠ 0)
(1, 7.5)
x = 1
y = 7.5
↓
7.5 = ab
(3, 16.875)
x = 3
y = 16.875
↓
16.875 = ab³
7.5 = ab
b b
7.5/b = a
16.875 = ab³
b³ b³
16.875/b³ = a
7.5/b = 16.875/b³
7.5/b(b³) = 16.875/b³(b³)
7.5b² = 16.875
7.5 7.5
b² = 2.25
√(b²) = √(2.25)
b = 1.5
a = 7.5/b
a = 7.5/1.5
a = 5
y = 5(1.5)ˣ
I would say b makes the most sense.
Hopes this helps!!Good luck!!
