Answer:
x=100º
Step-by-step explanation:
The two angles are vertical angles, so they are congruent.
Answer:
-70
Step-by-step explanation:
This is not an expression due to the =, because that makes it an equation. So I will assume the = is a +, to make it an expression.
1. Combine all negative numbers: -68 - 4 - 3 = -75
2. Add to 5, -75 + 5 = -70
9^6
The answer is nine the power of six
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.
