Both the first choice and the fourth choice are correct because the sum of supplementary angles is 180°
Answer:
-9x²
Step-by-step explanation:
-(3x)²
In PEMDAS, we solve the exponent first then multiply.
-(3x)²
-(9x²)
-9x²
Best of Luck!
Answer:No
Step-by-step explanation:
first values is 3x+x = 4x
second value is x(2+1) = x(3) = 3x
since 3x!=4x . answer is no.
Slope is change in y over change in x. From 0 to 10 we change by 10 so 10/x=2. The change in x=5 but you’re not looking for the change in x. You’re looking for a value that would give you change in x being 5 which would be 0. 0 to 5 gives us a change in x of 5. 10/5 is 2 which is the slope.
