2,8 -4,-4 what is the slope

emmasim [6.3K]

Answer:

For (2, 8) the slope is 2

For (-4, -4) the slope is -4

Step-by-step explanation:

The slope is the x axis which goes first

and the y intercept would be the y axis which goes second

Slope goes before the y intercept

for example: (8, 4) the slope is 8 the y intercept is 4

A gardener wants to create a rectangular vegetable garden in a backyard. She wants it to have a total area of 120 square feet, a

erastova [34]

Comment
This is an area problem. The key words are 120 square feet and 12 feet longer.
And of course width is a key word when you are reading this.

Formula
Area = L * W

Givens
W = W
L = W + 12

Substitute and Solve
Area = L* W
120 = W*(W + 12)
W^2 + 12W = 120 square feet
w^2 + 12w - 120 = 0

This does not factor easily. I would have thought that a graph might help but not if the dimension has to be to the nearest 1/100 of a foot. The only thing we can do is use the quadratic formula.

a = 1
b = 12
c = - 120

w = [ -b +/- sqrt(b^2 - 4ac) ]/(2a)
w = [-12 +/- sqrt(12^2 - 4*(1)(-120)] / 2*1
w = [-12 +/- sqrt(144 - (-480)]/2
w = [-12 +/- sqrt(624)] / 2
w = [- 12 +/- 24.979992] / 2 The minus root has no meaning whatever.
w = (12.979992) / 2
w = 6.489995 I'll round all this when I get done

L = w + 12
L = 6.489995 + 12
L = 18.489995

check
Area = L * W
Area = 6.489995*18.489995
Area = 119.999935 The difference is a rounding error

Answer
L = 18.489995 = 18.49 feet
W = 6.489995 = 6.49 feet

Note: in the check if you round first to the answer, LW = 120.0001 when you find the area for the check. Kind of strange how that nearest 1/100th makes a difference.

The repayment schedule is for a $1,300 loan at 7.5% for 6 months. What is the amount for interest at payment 5?

max2010maxim [7]

Answer: The answer is $2.77.

Step-by-step explanation: Given that we have to pay the loan of $1300 at interest rate of 7.5% in 6 months. According to the table,

Amount for interest in payment 1 = $8.13,

Amount of interest in payment 2 = $6.79

and

Amount of interest in payment 3 = $5.45.

We can see here that the difference in the amounts to be paid in consecutive months will be same, i.e., the payments will form an arithmetic progression (A.P.).

The common difference = 8.13-6.79=6.79-5.45=1.34.

Therefore, amount of interest in payment 4 = $(5.45-1.34) = $4.11

and amount of interest in payment 5 = $(4.11-1.34) = $2.77.

Please see the attached modified table.

Thus, the answer is $2.77.
