If f(x) = -9x +9 and g(x)+squroot x+1, what is (f degree sign g) 24
Leno4ka [110]
(f ° g) (x) means the composition of the two functions in this order f (g (x) )

So, given f(x) = - 9x + 9 and g(x) = √(x + 1),  you must do this:

f(g(x)) = - 9 [ g(x) ] + 9 = - 9 [√(x+1) ] + 9 => f(g(24) = - 9 √(24 + 1) + 9 = - 9√25 + 9 =

= -9(5) + 9 = -45 + 9 = - 36

Answer: - 36

I don’t know how to graph two equations that 2w+2l=228 and l=w+42 and calculate the w and l.
Reika [66]

Solve for w and l by using the system of equations.

2l=-2w+228

l=w+42

Substitute w+42 for l in the first equation.

2(w+42)=-2w+228

2w+84=-2w+228

4w=144

w=36

Now substitute 36 for w in any equation to get l=78.

To graph the equations, first make them equal l.

l=-w+114 and l=w+42 are your equations. You ca plug in values for w to plot points on the graph.

On a coordinate plane, point A is 3 and one-half units to the left and 2 and one-half units up.
goldfiish [28.3K]

<u>Answer:</u>

  • A: (Negative 3 and one-half, 2 and one-half)

<u>Solution:</u>

On a graph, left would be a negative and up would be a positive. Hence the answer is A as none of the others are using the correct numbers.

Hope this helped!
