Answer:
A
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
y = 8x - 4 → (2)
Substitute y = 8x - 4 into (1)
8x - 4 = x + 3 ( subtract x from both sides )
7x - 4 = 3 ( add 4 to both sides )
7x = 7 ( divide both sides by 7 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting into (1)
y = 1 + 3 = 4
solution is (1, 4 ) → A
use the pythagorean theorem:
I think it is C
If I'm wrong try B
