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.
Answer:
-The answer is 
.
Step-by-step explanation:
When you divide numbers/variables with exponents, the exponents will subtract each other:
(-2x + 3) - (7x -10)
= (-2x + 3 - 7x +10)
<h2><u>= 13 - 9x</u></h2>
Hope this will help...
