Step-by-step explanation:

To find your answer you first have to multiply the numbers that aren’t in parentheses and you multiply 2 and 7 and you get 14 then you  don’t have to worry about the x because it is a variable so now add  -4 +2. but first we have to turn negative into positive so you add -4 + 8

Vanyuwa [196]

Answer:

  6.9%

Step-by-step explanation:

Interest rate is the one variable in an amortization formula that cannot be determined explicitly. An iterative solution is required, which means the computation must be done by a calculator, spreadsheet, or web site.

My TI-84 TVM Solver tells me that for the given loan amount and payment schedule, the APR is about 6.9%.

The length of a rectangular book is 2 times its width. The perimeter of the book is 42 inches. Write a system of
wel

Answer:

Mark me as brainlist

Step-by-step explanation:

P = Perimeter            

L = Length          

W = Width

Perimeter of rectangle = L + L + W + W        

or P = 2L + 2W

You know:

P = 36 inches

L = 2W          [length is(=) 2 times it's width]

W = ?

P = 2L + 2W    

Substitute/plug in what you know, plug in 2W for L since L = 2W

36 = 2(2W) + 2W         Simplify

36 = 4W + 2W

36 = 6W        Divide 6 on both sides

6 = W              Now that you know the width, you can find the length:

L = 2W

L = 2(6)

L = 12

L = 12 in

W = 6 in

PROOF

P = 2(12) + 2(6)

P = 24 + 12

P = 36

Which represents the domain of the relation {(–1, 4), (2, –3), (0, –2), (1, –3)}?
Fantom [35]
Domain means the “input” which is like when u input a number in a vending machine and then the output is you getting the chips or whatever u got from imputing the number. So the answer would be C because is is asking for the front numbers in the relation or plots of points.
