The answer is 90 because you need to do 6x15 which =90
They are not equivalent because 2/5 is equal to .4.
Answer:
Step-by-step explanation:
Given
Required
Find p, when 
We have:
Express as equation
Make k the subject
When:
When , we have:
okay. the point has an x and y value. place them into the equation.
1=m(1)+b
m=slope, and theequation tells you that slope is 7.
1=7(1)+b
now you need to figure out what b is.
1=7(1)+b
^
1= 7 +b
-7 -7
---------------
-6=B
b is 6. now place it into the equation, replacing the x and y values back.
y=7x-6.
write 7 and 6 in the boxes (the negative for the six has already been provided)
It's equal to 39 since that number multiplied by itself three times equals 39. i hope it makes sense.
