Answer:
4
Step-by-step explanation:
It's easy because 4-4=0 and anything divided by zero is zero.
Answer:

Step-by-step explanation:
So you have (16, 1)
When two linear functions are parallel, they have the same slope.
So function q also has a slope of 1/3x. You have a set of points so you can plug them in a slope intercept equation to find b.
y= mx+b
m= slope
y= y-intercept
1= 1/3(16) +b
1 - (16/3) = b
b= -13/3
so then, 
Multiply eqn 1 by 3 and eqn 2 by 7 then adding them will cancel Y. and X can be found.
Answer
The anwser is C - Round 33 percent to 30 percent and 87 to 90. Think of 30 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 30 percent of 90 is 9 + 9 + 9, which is 27.
Step-by-step explanation:
I got the anwser correct first try on the quiz.
Hope this helps!
Answer:
Move the center of circle A to (1,7), then multiply its radius by 3.
Step-by-step explanation:
Moving the circles to the same center would make them concentric. Then, by multiplying the radius of Circle A by 3, the circle is dilated to the exact size of circle B, since its radius is 9. This shows that Circle B is proportional to Circle A, thus they are similar.
