The answer is c
based on the graph is showing the parent function is +x^3
3x - 5 = 7
3 x 4 = 12
12 - 5 = 7
So x is 4
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
<span>x= -8 + y
-9x + 6y= 9
substitute </span>x= -8 + y into -9x + 6y= 9
-9x + 6y= 9
-9(-8 + y) + 6y= 9
72 - 9y + 6y = 9
-3y = -63
y = 21
<span>x= -8 + y
</span><span>x= -8 + 21
x = 13
solution (13, 21)</span>
