The rate of change is 1/35 because the number of months(x) is increasing by 1( the numerator) and the total savings(y) is increasing by 35( denominator).

Answer:

Total money: $348.26

Step-by-step explanation:

Paige: $49.75

Nevaeh: 2.5*$49.75

Naomi: 3.5*$49.75

2.5*49.75 = 124.38

3.5*49.75 = 174.13

(I rounded the cents up.)

124.38

What percent of 80 is 10

True [87]

I believe that the answer is 12.5%

Reason 100% of 80= 80,

So if 80=100%,

then that means 10=x%

Fore it means that, $x=(\frac{10}{80} )*100$ %=12.5%

A line passes through the points (6,-6) and (9,-5). What is it’s equation in point slope form?

BARSIC [14]

Answer:

$y=\frac{1}{3}x-8$

Step-by-step explanation:

Slope-intercept form of an equation is written as $y=mx+b$ , where $m$ is the slope and $b$ is the y-intercept.

The slope of a line that passes through the points $(x_1,\: y_1)$ and $(x_2, \: y_2)$ is $m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}$ . Using the coordinates $(6,-6)$ and $(9,-5)$ as given in the problem, we have slope of this line to be:

$m=\frac{-5-(-6)}{9-6}=\frac{1}{3}$ .

Now using this slope we've found and any point the line passes through, we can find the y-intercept of this equation:

$-6=\frac{1}{3}(6)+b, \\ b=-8$

Therefore, the equation of this line in slope-intercept form is $\fbox{$y=\frac{1}{3}x-8$}$ .
