The function y = 45x + 300 can be used to model the cost of buying new furniture and making monthly payments over a period of x months. Which of the following best describes the y-intercept of the graph? Group of answer choices-

the monthly payment amount

the amount of the down payment

the number of pieces of furniture bought

the number of months to pay off the balance

The Answer is B

Step-by-step explanation:

If we are looking at money we are looking at the total amount u need to pay and if u are paying 45 a month times whatever x is. 300 would stand for the amount already paid or the down payment made.  

hi there!

the answer will be d: 2

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
