S+(2+1/2)s+20=48

2/2s+5/2s=48-20

7/2s=28

7s=28*2=2(20+8)=40+16

7s=56

s=56/7

s=8

use the slope formula to calculate the slope of the line that contains the two points (-4,0) and (5,2)​
Solnce55 [7]

Answer:

\frac{2}{9} x

Step-by-step explanation:

To find slope using two points you need to find the difference in x and y. You use \frac{y_{2}-y_{1}}{x_{2}-x_{1} }

So, 2-0=2 and 5-(-4)=9. Therefore the slope is 2/9x

The table represents a linear function.<br> What is the slope of the function?
TEA [102]

Answer:

-4

Step-by-step explanation:

The function is linear; therefore, the slope of the line joining any two points is the same.

We take any two points from the table and compute the slope or  rise/ run between them— let is take points (-4, -2) and (-2, -10).

The slope m of the line joining the points is

m=\dfrac{\Delta y }{\Delta x } =\dfrac{-2-(-10)}{-4-(-2)} \\\\\boxed{m=-4}

The slope of the function is -4.

y = 25x + 263 this equation represents how much money she will have, including her saving.

What is the linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

We have,

The saved amount of $263 by Jenna,

and also she earns $25 per day

if x represents the number of days she works,

and let's take y as the total amount she will have.

Then the equation becomes:
y = 25x + 263

Hence, y = 25x + 263 this equation represents how much money she will have, including her saving.
