A business purchases a computer system for $5,300. The value of the system decreases at a rate of 12% per year. In how many year

N76 [4]

Answer:

7

Step-by-step explanation:

If a system decreases by 12% it's the same as multiplying it by .12-1 or .88

This means we can create the following equation

computer value=5300(.88)^n

where n is the number of years

We can then plug in the value of the computer and solve for n

2200=5300(.88)^n

Divide by 5300 and get

.415=.88^n

Then put this into log form and get

$\frac{log(.415)}{log.88}$

Evaluate this into your calculator and get n=6.69 which I would probably just round to 7

If the gradient of a line joining the points (-2, 6) and (5, b) is 14.<br> Find the value of b.

babunello [35]

Answer:

b = 104

Step-by-step explanation:

Slope is expressed as;

m = y2-y1/x2-x1

14 = b - 6/5-(-2)

14 = b - 6/5+2

14 = b-6/7

Cross multiply

b-6 = 14 * 7

b - 6 = 98

b = 98 + 6

b = 104
