Answer 2

@Mehek14

Answer 3

for the first one C
-7x + 7x = 0

Answer 4

thanks so much ahhh <3

Answer 5

2nd one
(-6,-4)

Answer 6

3rd one
Line y = –2x + 8 intersects the line y = –x + 5.

Answer 7

4th one
no solution because the lines are parallel and never intersect

Answer 8

that's it ?

Answer 9

omggg ilysmmm hahahaaa

Answer 10

:)

Answer 11

i promise last one for today.. im sorry

Answer 12

Rachel is 11 years older than Scott. Rachel's age is 7 years less than two times Scott's age. The system below models the relationship between Rachel's age (r) and Scott's age (s):

r = s + 11
r = 2s – 7

Which is the correct method to find Rachel's and Scott's ages?

Solve r + 11 = 2r – 7 to find the value of s.
Solve s + 11 = 2s – 7 to find the value of s.
Write the points where the graphs of the equations intersect the x-axis.
Write the points where the graphs of the equations intersect the y-axis.

Answer 13

Solve s + 11 = 2s – 7 to find the value of s.

Answer 14
