plug in -4 in for x. then solve.
h(-4)=1/2(-4)-1
h(-4)= -3
Answer:
x= 56
Step-by-step explanation:
86+94= 180 which if supplementary angles have to equal 180°
I don't know if you can tell but what's in red means distribute
then I added 26 on both sides with like terms
on the left side 86+26=112 and right side is left with 2x
then divide both sides by 2 to leave x by itself
112/2= 56 and 2x/2=x
so 56=x
Answer:
Step-by-step explanation:
tan(30°) =
cot(30°) =
sin(60°) =
6 + 12 = 18
18/9 = 2
The answer is 2
Hope this helps
Answer:
Infinitely many solutions. Each real number is a solution of this equation.
Step-by-step explanation:
-5 + (-5r) + 10 = -5r + 5
5 - 5r = -5r + 5 <em>add 5r to both sides</em>
5 = 5 TRUE
