Answer:
The value of k is -5.
Step-by-step explanation:
To find the value of k, start by using the known information we have in the equation for slope. The equation is below.
m(slope) = (y2 - y1)/(x2 - x1)
In this equation, the first ordered pair would be (x1, y1) and the second would be (x2 , y2). So we put the values in for these variables and we get.
-1/5 = (-7 - k)/(6 + 4)
-1/5 = (-7 - k)/10
Now we can use cross multiplication to solve for k.
-1/5 = (-7 - k)/10
-1*10 = 5(-7 - k)
-10 = -35 - 5k
25 = -5k
-5 = k

Answer:
Part 1. He would need to sell 8 Cars
Part 2. He would need to sell at least 15 cars
Part 3. 64,800 Would be your minimum value
Step-by-step explanation:
Part 1:
Start with x = the number of cars that he sells. So 250x +2400 =4400
250(8)+2400=4400
Part 2.
Same equation but you are looking for 6000 dollars or right over.
250(14)+2400=5900
So you would need it to be 15 cars, 250(15)+2400=6150
Part 3.
You we need to get the value for 12 cars, so
250(12)+2400=5400 then multiply that by 12 for a year
5400*12=64,800 Would be your minimum value
Equation: f(x)=(1/5)x^2 or f(x)=(0.2)x^2
Check:
f(0)=(1/5)(0)^2
f(0)=(1/5)(0)
f(0)=0✓
f(5)=(1/5)(5)^2
f(5)=(1/5)(25)
f(5)=5✓
Four to the fifth power is...
4•4•4•4•4=1,024
