X=(-9y/8)-29/8
y=(-8x/9)-29/9
Answer:
<em>102°</em>
Step-by-step explanation:
(3x - 12)° + (2x + 2)° = 180°
5x - 10 = 180 ⇒ x = 38
m∠A = (3x - 12)°
<em>m∠A</em> = (3×38 - 12)° = <em>102°</em>
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.
