Sara wants to buy diapers online. She is considering two different diaper delivery services. The first store charges $45 per case and the delivery charge is $25.
The second store gives the total price (P in dollars) as a function of the number of cases (c ) as
P = 35 + 30c.
Which of the following statements are true about the two stores? Select all that apply.
The first store charges more per case than the second store.

The rate of change for the first store is greater than the rate of change at the second store.

If I need to buy 10 cases of diapers, I will get them cheaper from the second store.

Initially, the first store will be cheaper but over time, the second store becomes cheaper.

The y-intercept of the second store is greater than the y-intercept of the first store.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

it would open into a square depending on the type of envelope i’m not sure about the second part

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
