Answer:
(-5,1)
Step-by-step explanation:
To eliminate x, multiply the first equation by 3 and add 2 times the second equation.
3(-2x +7y) +2(3x -4y) = 3(17) +2(-19)
-6x +21y +6x -8y = 51 -38
13y = 13
y = 1 . . . . . matches the third answer choice
(x, y) = (-5, 1)
A=s^2
A=6.3^2
(A=6.3x6.3)
And your answer would be:
A=39.69cm^2
Answer: 8 is the slope
Step-by-step explanation:
Y-7=8(x-14)
Y-7= 8x-112
Y= 8x -105
