20 points margaret earns $15.25 an hour working at a record store and is paid every week. she takes $50 from each paycheck and puts it in her savings account. she spends the remainder of her paycheck.

part a: identity the variables y, m, x, and b in the given situation. explain each variable.

part b: write the linear equation that represents the given situation z

part c: explain how the equation from part b can be used in relation to the given situation.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

answer: x=3 and y=4

step-by-step explanation:

answer: 60%

explanation:

÷

= 60%

answer: i believe it is c

step-by-step explanation:

because 5+4=9 so it would be 3^9
