Answer:
the answer you picked in the pictures is the correct one
Answer:
x = -5 y = -9
Step-by-step explanation:
y = x -4
5x + y = - 34
substitute x-4 in for y to solve for x
5x + x - 4 = 34
solve for x . . . add 5x + x = 6x
so you now have 6x-4 = -34
add 4 to both sides of the equation
6x-4 + 4 = -34+ 4
6x = -30
divide both sides by 6
6x/6 = -30/6
x= -5
then you plug -5 for x in the first equation
y = x - 4
y= -5 -4
y =-9
x= -5 y= -9
A is the correct answer because it is the only one that shows the angles that add up to 180 degrees on a line since a supplementary angle is on the line and will add up to 180. D would be correct if angles 6,4,and7 were placed together as those angles together wake a line but no, this means A is the correct answer
F(x) = 1/4x-1
i hope this helps!
