Answer: 15
Step-by-step explanation:
Each side of the smaller triangle is scaled up by 2.5.
4x2.5=10
8x2.5=20
6x2.5=15
Answer:
m=22.5
Step-by-step explanation:
m is proportional to n means there is some constant k such that:
m=kn
If m=5 when n=4 then we have the following equation to solve for our constant k:
5=k(4)
5=4k
Divide both sides by 4:
5/4 =k
So k=5/4 no matter what (m,n) pair they give you where the equation is m=kn.
m=(5/4)n
What is m when n=18?
m=(5/4)(18)
m=(5/2)(9)
m=45/2
m=22.5
right 3 units down 5 units

right 3 units = (3,0)
down 5 units = (0,-5)
vertex = (h,k) therefore.

Then convert the vertex form into standard form for the equation in the choice.

Thus, the answer is B.
The decimal of 2.1 is greater than 2.0 but less than 2.42
