Answer:
4x² + 18
Step-by-step explanation:
note that (c ○ d )(x) = c(d(x))
To evaluate substitute x = d(x) into c(x), that is
c(d(x))
= c(x² + 5)
= 4(x² + 5) - 2
= 4x² + 20 - 2
= 4x² + 18
Answer:
x^2 + 14x + 49 = 0
Step-by-step explanation:
Simplify the expression and you get: 8.6
Hope this helps!
4x - 5y = 40
4x = 40 + 5y
x = 10 + 5/4y
The x intercept is 10.
30 is 50% of 60 because 50% is a half
