Answer:
x=25
Step-by-step explanation:
because of vertical angles theorem you set them equal to each other
4x+50=150
subtract 50 from both sides
4x=100
devide by 4 on both sides
x=25
The only solution is (-3/2, 4)

Answer:
The value of y in the given equation is B. 30.
Step-by-step explanation:
y = 2x² - 4x x = 5
y = 2(5)² - 4(5) Plug 5 in for x
y = 2(25) - 20 Square 5 and multiply 4 by 5
y = 50 - 20 Multiply 2 by 25
y = 30

Hello :
<span>4x-5y=13...(1)
x+5y=-3...(2)
(1)+(2) : 5x = 10
x=2
subsct in (2) : 2+5y = -3
5y =-5
y = -1
