F(g(x)) means you take the g function and put it into x in the f function. He took the function and put it into the g, which was the incorrect order. He should have had this:
Answer:
Step-by-step explanation:
F(x) =5x + 1 , find f(-4)
Putting value of x = 4
F(4) = 5(4) + 1
= 20 + 1 = 21
Answer:
x>17/9
Step-by-step explanation:
-3(x-2) < 1/3
-3x+6 < 1/3
-3x < 1/3-6
-3x < -17/3
x > 17/9
The quadratic formula is
.
From the problem, a is 1, b is -1, and c is 12. Plugging in these values gives:

Because there is a square root of a negative number, there is no solution.
Answer:
it is D
Step-by-step explanation:
the ratio is 1.5 so multiply 15 by 1.5
