Write out the algebraic expression given in each written expression. 7 plus the product of 9 and a is 7
A a(7+9)=7
B 7(9+a)=7
C (7+a) 9 = 7
D 7 + 9a = 7

D

Step-by-step explanation:

1) rewrite 7 plus as

7 +

2) rewrite “the product of 9 and a“ as

9a remembering that a product can be written without a sign that indicates the operation

3) match the two informations

7 + 9a

4) rewrite “is 7” as:

= 7

5) write the final expression

7 + 9a = 7

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

because that’s us why
