At 0 minutes, Raul paid $4.00 meaning it is the fixed fee paid up front (y-intercept).

Every 2 minutes the amount paid goes up by $0.12 or 0.06 per minute.

y = 0.06x+ 4

100 POINTS

Answer:

Part A) $m=3$

Part B) $m=1$

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

Part A) Determine the slope for the line that passes through the points (3,5) and (−1,−7)

substitute the values in the formula

$m=\frac{-7-5}{-1-3}$

$m=\frac{-12}{-4}$

$m=3$

Part B) Determine the slope for the line that passes through the points given by the table of values

Looking at the given table, take two points

(0,-5) and (2,-3)

substitute the values in the formula

$m=\frac{-3+5}{2-0}$

$m=\frac{2}{2}$

$m=1$

a rectangle bookcase 60 inched long and 30 inches wide. how long is the diagonal? round to the nearest inch

yuradex [85]

It will be roughly 67.08 inches.

We can solve this using the Pythagorean Theorem, which is listed below.

$a^{2} + b^{2} = c^{2}$

In this equation, we use a and b as legs of a triangle and c is the hypotenuse. We can treat the length and height of the bookcase as legs and use this equation to solve for the diagonal (also known as the hypotenuse)

$30^{2} + 60^{2} = c^{2}$
