Question

y = 25x + 32
y = 5x² + 25x - 13
how do i find the two pairs of coordinates

Answer 1

Answer:

(-3,-43) and (3,107)

Step-by-step explanation:

input 25x+32 for y

25x+32=5x²+25x-13

32=5x²-13

-5x²=-45

x²=9

x=+-3

which means you separate the solution

x= -3

x= 3

then input the answers you got for x, in both equations. Then you'll get your y.

y=25(-3)+32

-43

Then check your answer.

Then input the other answer you got for x.

I may be wrong, but I tried and checked my answers.
