What is the equation of the line through (-2,-2) and (4,-5)?
svp [43]

Answer:

y=-3.5x+9

Step-by-step explanation:

the slope is determined by the y1-y2/x2-x1 which is equaled to -5-2/4-2 which is equaled to -7/2 which is -3 1/2 which is your m value in y=mx+b and you graph to get your b value (y-intercept) which is 9

a boat costs $16600 and decreased in value by 14% per year. How much will the boat be worth after 11 years?
mr_godi [17]

The worth of boat after 11 years is $ 3159.3013

<em><u>Solution:</u></em>

Given that,

Boat costs $16600 and decreased in value by 14% per year

To find: Worth of boat after 11 years

<em><u>The formula for decreasing function is given as:</u></em>

y = a(1-r)^t

Where,

y is the value after "t" years

t is the number of years

a is the initial value

r is decreasing rate in decimal

<em><u>From given,</u></em>

a = 16600

t = 11

r = 14 \% = \frac{14}{100} = 0.14

<em><u>Substituting the values we get,</u></em>

y = 16600(1-0.14)^{11}\\\\y = 16600(0.86)^{11}\\\\y = 16600 \times 0.1903\\\\y = 3159.3013

Thus the worth of boat after 11 years is $ 3159.3013

Isolate for r, d = 2r
e-lub [12.9K]

Answer:

D/2=r

Step-by-step explanation:

Since we want r to be by itself what we can do is divide 2 on both sides so 2 can cancel out on 2r and when you divide on both sides your left with d/2=r
