Answer:
function f(x) = x + 3 has a zero at x = 3 since f(3) = 0.
Step-by-step explanation:
She gonna need to buy 32 boxes because 315 divided by 10 is 31 r 5 and also you can't buy 31 boxes because 5 kids aren't gonna have pencils so she needs to buy 32 boxes of pencils
5% = 5/100 = 1/20;
12% = 12/100 = 3/25;
15% = 15/100 = 3/20;

The fraction of the books that are reference books is 5/14 i think. hope that helps !!
Since our line is perpendicular to this line, the slope of
our line is the negative reciprocal of 1/4, which is -4/1.
Remember, negative reciprocal is just a fancy way
of saying flip the fraction and change the sign.
So the slope of our line is -4/1 and we use this slope along
with our given point to write the equation of our line.
Start with the point-slope formula.
Y - y1 = m(x - x1).
~Substitute
Y - -2 = -4/1(x - 5).
Minus a negative is plus a positive.
Y + 2 = -4/1x + 20.
Subtract 2 from both sides.
Y = -4/1x + 18
So, our answer is C.
