Look in the table at the column that has 1 minute and 4.25 pages. Printer A prints 4.25 pages in 1 minute which is a rate of 4.25 pages per minute. The rate of printing is the slope in the equation. A rate of 4.25 pages per minute is represented by the equation y = 4.25x, where 4.25 ids the slope of the equation.
We are told that Printer A prints faster than Printer B, so Printer B must have a lower rate of printing than Printer A. The equation for Printer B must have a slope less than 4.25.
There are two choices which have a slope less than than 4.25.
Answer: y = 4.2x; y = 4x
The total of Pizzas is 16.
16×1/4 =4 So by halftime they ate 4 pizzas.
This statement will be
false. -7+9=2
-9+7=-2
, therefore, this statement is false.
F(x) = 15 <=> 4|x-5| + 3 = 15
<=> 4|x-5| = 12
<=> |x-5| = 3
<=> x-5 = 3 (1) <=> x-5 = -3 (2)
<=> x = 8 (1) <=> x = 2 (2)
x = 8; x = 2
