I NEED THIS ASAP :3 When Alexis bought groceries, she received a discount of 25%. Write an expression to represent the sale price of the groceries.

x-y

Step-by-step explanation:

Lets say the normal price without the sale is y then you divide y by 4 then the price you got from dividing y by 4 is x. Now to get your answer you do this x-y. I hope this makes sence and helps

a natural event such as a flood, earthquake, or hurricane that causes great damage or loss of life.

step-by-step explanation:

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
