PLEASE HELP the formula m=12,000+12,000rt/12t gives keri's monthly loan payment where t is the annual interest rate and t is the
tatiyna

Answer:

The answer is below

Step-by-step explanation:

The formula m = (12,000 + 12,000rt)/12t gives Keri's monthly loan payment, where r is the annual interest rate and t is the length of the loan, in years. Keri decides that she can afford, at most, a $275 monthly car payment. Give an example of an interest rate greater than 0% and a loan length that would result in a car payment Keri could afford. Provide support for your answer.

Answer: Let us assume an annual interest rate (r) = 10% = 0.1. The maximum monthly payment (m) Keri can afford is $275. i.e. m ≤ $275. Using the monthly loan payment formula, we can calculate a loan length that would result in a car payment Keri could afford.

m=\frac{12000+12000rt}{12t}\\ but\ m\leq275, \ and \ r=10\%=0.1\\275= \frac{12000+12000(0.1)t}{12t}\\275= \frac{12000}{12t} +\frac{12000(0.1)}{12t}\\275= \frac{1000}{t} + 100\\275-100= \frac{1000}{t} \\175= \frac{1000}{t} \\175t = 1000\\t= \frac{1000}{175}\\ t=5.72\ years

The loan must be at least for 5.72 years for an annual interest rate (r) of 10%

Can someone Explain the whole matrices chapter? Like only the basic, addition, subtraction, multiplication and division, of matr
Free_Kalibri [48]

Step-by-step explanation:

The important rule to know is that when adding and subtracting matrices, first make sure the matrices have the same dimensions. In order words, you can add or subtract a 2x3 with a 2x3 or a 3x3 with a 3x3. However, you cannot add a 3x2 with a 2x3 or a 2x2 with a 3x3.

What is the solution to y=5x-7 -3x-2y=-12
likoan [24]
y=5x-7 \\
-3x-2y=-12 \\ \\
\hbox{substitute 5x-7 for y in the 2nd equation:} \\
-3x-2(5x-7)=-12 \\
-3x-10x+14=-12 \\
-13x+14=-12 \ \ \ |-14 \\
-13x=-26 \ \ \ |\div (-13) \\
x=2 \\ \\
y=5x-7=5 \times 2-7=10-7=3 \\ \\
\boxed{(x,y)=(2,3)}
