Nurbanu uses a copy machine to enlarge her rectangular design that is 6 inches wide and has an area of 48 square inches. If the enlarged design has a width of 15 inches, what is the area of the enlarged design?

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
