Let's solve your system by substitution.

−3x+y=−2;y=4x

Rewrite equations:

y=4x;−3x+y=−2

Step: Solvey=4xfor y:

y=4x

Step: Substitute4xforyin−3x+y=−2:

−3x+y=−2

−3x+4x=−2

x=−2(Simplify both sides of the equation)

Step: Substitute−2forxiny=4x:

y=4x

y=(4)(−2)

y=−8(Simplify both sides of the equation)

Answer:

x=−2 and y=−8

Greta takes out a loan of $35,000 the rate of compound interest is 2% per month after 6 months she wants to pay off the loan and
zimovet [89]
To solve this problem, we must use the Time Value of Money equation.

Future Value = Present Value * (1 + interest rate per month)^number of months

F = 35,000 * (1.02)^6 = 39,415.68

A. She will have to pay $39,415.68 altogether.

To find payment in interest, we must subtract the initial loan of $35,000 from $39,415.68

39,415.68 - 35,000 = 4,415.68

B. She will have to pay $4,415.68 in interest.

Please help, my teacher is going mad!
Leni [432]

Answer:

It is a rectangle.

LENGTH = 5 X+2   IF X = 5        L = 5×5+2 =25+2=27

L=27

BREADTH = X+8 IF X=5     B =5+8= 13

B= 13

Area of the rectangle = L× B

                                       =27×13

                                    = 351

Perimeter of the rectangle=2(l+b)

                                        =2(27+13)

                                     =2×40

                                    =80
