Can somebody help me with 6 and 7 and show the work for it? thank you

Answer:

Answer For Number 6 is $30

Step-by-step explanation:

We can find how much molly would save by first finding out how much 20% of $275 is. We can do that by multiplying 275 by 0.20 since 0.20 is 20% in decimal form

275*0.20 = 55

Now that we know 20% of 275, we can find the price of the microwave at store B by subtracting 55 from the original price.

275 - 55=220

Now we can find how much Molly would save by subtracting our discounted price from the price of the microwave from store A

250-220=30

Hence, the amount she would save is $30

Which of the following are point slope equations of the line going through (-3, -5) and (2, 4). Help is appreciated!​
ki77a [65]

Answer:

A and F

Step-by-step explanation:

first figure out the slope.

4-(-5)/2-(-3)= 9/5

slope: 9/5

y-y1=m(x-x1)

you substitute either coordinate for the second variables. we automatically take out any slopes that have a negative because the slope is positive.

C, D, E all have negative slopes so it is wrong.

B does not work because a negative times a negative is a positive. the equation shows it to be negative so it is wrong.

A & F fit the solution.
