Given f(x)=7x-9 and g(x) =x^2, choose the expression for (f*g)(x)

Travka [436]

ANSWER

$(f\circ g)(x)=7 {x}^{2} - 9$

EXPLANATION

It was given that;

$f(x) = 7x - 9$

and

$g(x) = {x}^{2}$

We want to find an expression for the composition function;

$(f\circ g)(x)=f(g(x))$

$(f\circ g)(x)=f( {x}^{2} )$

We substitute x² into f(x)=7x-9

This will give us:

$(f\circ g)(x)=7 {x}^{2} - 9$

HELPPP....PLEASE...........

Answer:

9 1/3, 12 1/2, 14 3/4

Step-by-step explanation:

I assume the formula you’re working with is A=b*h since nothing says otherwise...

((Patio 1))

So you have your area (147) and your base (15 3/4), now you need to plug them in, which should look like this:

147= 15 3/4*h

You need to isolate your h in order to get the missing number, so you should divide both sides by 15 3/4 OR 63/4 ((15*3—>60+3=63))

Dividing by a fraction is the equivalent of multiplying by its reciprocal... so

147 * 4/63 = 588/63 which can be simplified to 84/9 once both the numerator and denominator are divided by 7

In mixed number for it is 9 3/9 which simplified becomes 9 1/3

You solve the other similarly

2x + 49 = -8 (-x-5)<br> Show your work please :D

melomori [17]

Answer:

2x + 49 = -8 (-x-5)

x=-57/2

x=-28.5

because if you substitute x for 28.5, it makes it equal
