Just combine like terms: all of the x^2 together, all of the x's together and all of the numbers:
3x2+5x2+5x-2-1
8x2+5x-3 simplified, so letter A
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
Move the decimal to the right 4 places to get 4 x 10^-4 which reads four times ten to the negative fourth power
True true and the last one is false
