graph the line that passes through the points (-8,9) and (4,-3) what are the x and y intercepts for this line someone help pleas

VashaNatasha [74]

Answer:

(0,1)- y intercept (1,0) x intercept

Step-by-step explanation:

first lets write this equation in slope intercept form: y=mx+b

m=slope

b=y intercept

so

slope formula:

(y2-y1)/(x2-x1)

y2=-3

y1=9

x2=4

x1=-8

so

(-3-9)/(4--8)=-12/12=-1

slope=-1

hence

y=-1x+b

substitute "x" as 4 and "y" as -3

so

-3=-1(4)+b

-3=-4+b

1=b

so

y=-x+1

1=y intercept

and

0=-x+1

-1=-x

1=x

1=x intercept

Jason bought a car for $12500. According to the insurance company, the value of the car depreciates by 7% each year. What will t

Orlov [11]

Answer:

8696.10

Step-by-step explanation:

If a car depreciates by 7% each year, this means that 7% of its value that year is subtracted from its previous value. In other words, you can multiply its value by (1-0.07)=0.93.

$12500\cdot 0.93^5\approx 8696.10$ . Hope this helps!

A population of rabbits in a lab, p(x), can be modeled by the function p(x) = 20(1.014)x , where x represents the number of days

Nitella [24]

Answer:

20 = initial population of the rabbits

1.014 = growth rate of the rabbits

the average rate of change from day 50 to day 100 is 0.8

Step-by-step explanation:

A population of rabbits in a lab, p(x), can be modeled by the function

p(x) = 20(1.014)^x

This model is exponential. Where 20 = initial population of the rabbits

1.014 = growth rate of the rabbits with 1.4% increase rate of the rabbits

To find the average rate of change from day 50 to day 100,

find the population p(50) and p(100). Subtract them and divide by 100 - 50 = 50.

p(50) = 20(1.014)50 = 40.08...

p(100) = 20(1.014)100 = 80.32...

(80.32 - 40.08) / (100 - 50) = 40.24/50 = 0.8048. which is approximately 0.8 to the nearest tenth.

The rate of change is 0.8.
