Answer:
144
Step-by-step explanation:
exponents first: 
then division: 100/5 = 20
now we have: 20 x 4 + 64
then multiply: 20 x 4 = 80
then add: 80 + 64 = 144
Answer:
Z is 
Step-by-step explanation:
We can rewrite the equation as P+Prz = B
Next, we can subtract the equation from both sides to get Prz = B - P
Finally, we divide both sides by Pr to get our final answer.
Looks as tho' you'll need to derive a function whose input and output values are represented by the given table. First, let's assume that the function is a linear one and that its general form is y=mx+b, where m=slope and b=y-intercept.
Take any two pairs of input-output and find the slope of the line segment that connects these two points. Call the slope "m."
Now use the point-slope form of the equation of a straight line to determine the equation of the line in point-slope form: y-k=m(x-h). You already know the value of m here, and you can pick any set of x- and y-values from the table to replace (h,k).
Good idea to double-check that your equation really does represent every pair of x- and y-coordinates in the table.
Assuming that it does, solve your equation (above) for x. Substitute 16 for y in this equation for x. Calculate the x-value that corresponds to y=16.
