A student answered 76 problems on a test correctly and received a grade of 80%. How many problems were on the test, if all the problems were worth the same number of points?

The total numbers of problems is 95

Step-by-step explanation:

Let the total numbers of problems be x

So, Total no. of problems x is 100%

Correct no. of problems on test  = 76

We are given that he  received a grade of 80%.

So, Correct no. of problems is 80 i.e. 80%

So,

Hence the total numbers of problems is 95

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
