Answer:
g(-2) = -1
Step-by-step explanation:
By looking at the graph, we can see that g(-2) where x = -2 is represented. Because x = -2, we can see that the y-value that correlates to this x-value is -1.
So g(-2) = -1.
Answer:
1.400 as a common fraction is 7/5
as a percentage 140%
Step-by-step explanation:
1.4 written as a fraction is;
simplifying we have;
Converting to percentage we simply multiply by 100.
1. The value of (cd)(x) is equal to the product of c(x) and d(x) which is equal to,
5(x + 3) / (x - 2)
The function can take all real numbers except 2 because that would make the denominator 0.
2. To answer, substitute first 5 to the given functions,
f(x) = 7 + 4x = 7 + 4(5) = 27
g(x) = 1/2x = 1 / (2)(5) = 1/10
Dividing 27 by 1/10 is 270.
-13 +3x +8 = 3x + (-5)
-9x + 15 - x -10 = -10 x + 5
The other two don't match
