Answer:
a. y = 3x + 4.5 & y = 7x + 2
b. x = 0.625 (year)
c. 6.375 feet
Explanation:
Type A starts at 4.5 and Type B starts at 2 ,each year can be marked as x
type A grow 3 inches per year = 3x
type B grows 7 inches per year = 7x
y = the total height
Since they both equal to y, you can set them equal to each other
3x + 4.5 = 7x +2
After solve you get answer for b
Work: 3x + 4.5 = 7x + 2
4.5 = 4x + 2
2.5 = 4x
0.625 = x
Substitute the value of x you got from part b into each equation then you will get 6.375 as your y value which is also your height
Answer:
c. $467.29
Step-by-step explanation:
The total of balances is $9360. The payment can be computed using the amortization formula:
A = P(r/12)/(1 -(1 +r/12)^-n)
where A is the monthly payment, P is the principal (total balance), r is the annual rate, and n is the number of months.
Filling in your numbers, we have ...
A = $9360(0.18/12)/(1 -(1 +0.18/12)^-24) ≈ $467.29
Frank's monthly credit card payment will be $467.29.
Answer:
slope of the line is 0
Step-by-step explanation:
given points are:
(-3 , 2)=(x1 , y1)
(4 , 2)=(x2 , y2)
slope =y2 - y1/x2 - x1
=2-2/4-(-3)
=0/4+3
=0/7
=0
