Answer:
x=27
Step-by-step explanation:
The two angles are vertical angles, which means they are equal
4x+7 = 5(x-4)
Distribute the 5
4x+7 = 5x-20
Subtract 4x from each side
4x+7 -4x = 5x-4x -20
7 = x-20
Add 20 to each side
7+20 =x-20+20
27 = x
Y = ²/₃x + 7
y = ²/₃(5) + 7
y = 3¹/₃ + 7
y = 10¹/₃
(x, y) = (5, 10¹/₃)
Answer:
yes
Step-by-step explanation:
2(2(3)+1) + 3= 8(3)+2-3(3)
14+3=24+2-9
17=17
The answer for the first one would be: y=3-2x
The answer for the second one would be: y=9-x
