Answer: -5 and 2
Because it equals 3 when added.
And -10 when multiplied.
Answer:
The answer would be d(c(x)) = .60x - 5
Step-by-step explanation:
In order to write an equation for d(c(x)), start with the d(y) equation.
d(y) = .80y - 5
Now input the c(x) equation in for y and then solve.
d(c(x)) = .80(.75x) - 5
d(c(x)) = .60x - 5
Check the picture below.
let's notice that the base of the pyramid is triangle with a base of 5 and an altitude of 4, so it has an area of (1/2)(5)(4).

Answer:A
Step-by-step explanation:
You use the equation:
m= (y2-y1) ÷ ( x2-x1)
m= (12-9) ÷ (2-1)
m= 3÷1
m= 3
Slope (y2-y1)/(x2-x1)
Pick any random points
(1,0) and (0,3)
(3-0)/(0-1) = 3/-1 = -3
The slope is -3
It is already graphed?
