Find how much 1 box costs by dividing.
9 ÷ 5 = 1.80
Now, multiply 1.80 by 20.
1.80 × 20 = 36
<h2>Answer:</h2>
<u>20 boxes of cookies costs </u><u>$36</u><u>.</u>
Answer
No. The amounts of change are the same, but the original amounts are different. The ratio for the percent increase from 50 to 70 is 20/50, or 40%. The ratio for the percent decrease from 70 to 50 is 20/70, or about 29%.
Polynomials are algebraic expressions that contain more than two terms. AN example would be: f(x) = x^3 + x^2 + x +1. This equation contains three terms, with the 3rd degree as its highest term. It also means that the graph passed three x-intercepts. This depends in the highest degree. So, the first thing you do is plot the intercepts because for sure, the graph will pass there.
(3,2). 3^2 + 2^2 = 13 2(3)-2= 4 Works for both, hence this is the intersecting point of the two lines.
