Answer:
choice D
a function is loosely defined as having one output for each input. in real people words, the x value can't repeat
7-x=15
7-(-8)=15
what we have to do in order to solve this is change the 2 subtraction signs into a addition sign because a negative plus a negative makes a positive.
Answer:
C is correct I think.
Step-by-step explanation:
Tell me if I am right.
Have a nice day!
plug a=2 and b=4 in the expression
5(2)+7(4)
simplify
10+28
solve
=38
Answer:
b = 12
Step-by-step explanation:
Complementary angles add to 90 degrees
a+b = 90
78+b = 90
Subtract 78 from each side
78-78+b = 90-78
b = 12
