Answer:
(h,k)
Step-by-step explanation:
f(x) = a|x-h| +k
This is written in vertex form where (h,k) is the vertex
Answer:
A
Step-by-step explanation:
complementary angles are 90 degrees so if we add both angles together we get 90 degrees. the equation is x-3+x+5=90. then we do algebra and so it goes to x-3+x=85 then to x+x=88 then to 2x = 88 then to x = 44. now we just do 44+5=49 44-3=41
We want to get b alone so I would start by multiplying 2 to get it on the other side of the = sign. So then I have 2L=a-b. I would subtract a on both sides and then I would have 2L-a= -b. We don't want a -b so I would multiply everything by -1 so then the answer would then be a positive b= -2L+a
C because if you do 10^5 you get 100,000. Then you multiply it with 7.5 and get 750,000. Then 750,000x16,000 is 12,000,000,000 which is 1.2 x 10^9
