What is the rate of change between (-8,- 8) and (0,8)

iren [92.7K]

${ \qquad\qquad\huge\underline{{\sf Answer}}}$

We need to find thr rate of change (slope) of the line joining these two points ~

$\qquad \sf \dashrightarrow \: m = \dfrac{rise}{run}$

$\qquad \sf \dashrightarrow \: m = \cfrac{8 - ( - 8)}{0 - ( - 8)}$

$\qquad \sf \dashrightarrow \: m = \cfrac{8 + 8}{0 + 8}$

$\qquad \sf \dashrightarrow \: m = \cfrac{16}{8}$

$\qquad \sf \dashrightarrow \: m = 2$

Slope of the line (m) joining the two points is 2 ~

A 14-ounce box of cereal sells for $2.10. What is the unit rate?

Ahat [919]

Answer:

The unit rate is equal to $0.15\frac{\$}{ounce}$

Step-by-step explanation:

we know that

The unit rate is the ratio of two measurements in which the second term is equal to one

In this problem to find the unit rate, divide the total cost of cereal by the total weight of cereal

$\frac{2.10}{14}\frac{\$}{ounces} =0.15\frac{\$}{ounce}$

therefore

The unit rate is equal to $0.15\frac{\$}{ounce}$

mylen [45]

Answer:

x = 35 degrees.

Step-by-step explanation:

(x\°) + (20+x) \°=90\°

want to solve for solve for x

2x = 90 - 20

2x = 70

x = 70 / 2

x = 35 degree
