Answer:

See below for answers and explanations

Step-by-step explanation:

<u>Part A</u>

10x - 12x - 3 does not equal -5x. Looks like what she did wrong was treating -3 as -3x and got her incorrect result that way

<u>Part B</u>

10x - 12x - 3 = (10-12)x - 3 = -2x - 3

Solve the system using substitution x=3y-11 4x-3y=-26
iragen [17]

Answer:

x=3y-11

then now putting the value of x in second equation

4(3y-11)-3y =26

12y - 44-3y=26

9y=44+26

9y=70

y=70/9

now putting the value of  y in 1st equation then

x=3*70/9-11

x=37/3

now checking this is correct or not in 2nd eqn

4*37/3-3*70/9=26

148-70/3=26

26=26

Suppose you borrow 13,000 for four years at 7% toward the purchase of a car.
dangina [55]
Amount borrowed, P = 13000
Interest, i = 0.07/12 per month
number of periods (months),  n = 4*12 = 48

Monthly payment, 
A=\frac{P(i*(1+i)^n)}{(1+i)^n-1}
=\frac{13000(.07/12*(1+.07/12)^{48}}{(1+.07/12)^{48}-1}
=311.30   (to the nearest cent)
