HELP you purchase a car using a $22,000 loan with a 6% simple interest rate for 5 years
Hunter-Best [27]

Answer:  (a) $6,600

                (b) $28,600

<u>Step-by-step explanation:</u>

Interest (I) = Principal (P) x rate (r) x time (t)

I = 22,000(0.06)(5)

 = 6,600


Accrued (A) = Principal (P) + Interest (I)

A = 22,000 + 6,600

  = 28,600

Which of the following equations represents a line that is perpendicular to y=-4x+9 and passes through the point, (4,5)?
kap26 [50]

Answer:

y = \frac{1}{4}x + 4 \\or\\4y = x + 16

Step-by-step explanation:

Given equation of line is:

y = -4x+9

Comparing it with the standard form

y = mx+b

m = -4

As we know that the product of slopes of perpendicular lines is -1

Let m1 be the slope of perpendicular line

m * m1 = -1

-4 * m1 = -1

m1 = -1/-4

m1 = 1/4

In order to find the value of b, putting the point in standard form

5 = (1/4)*4 + b

5 = 1 + b

b = 5-1

b = 4

Putting the value of b and m1 in standard form

y = \frac{1}{4}x + 4 \\or\\4y = x + 16 ..
