3(6-4x)-27x=10x-31

18-12x-27x=10x-31

18-39x=10x-31

-49x=-49

Therefore, x=1.


s/6-s/2+1=45/2.

s-3s+6=135

-2s=129

Therefore, s=-\frac{129}{2}.


2(b+5)=3(4-b)

2b+10=12-3b

5b=2

b=\frac{2}{5}

F(x)=2(3-x),find f(-7)
Sauron [17]

Answer:

f(-7) = 20

Step-by-step explanation:

Given:

f(x) = 2(3 -x)

Solving for f(-7):

f(-7) = 2(3 -(-7)) \\ f(-7) = 2(3 +7) \\ f(-7) = 2(10) \\ f(-7) = 20

If f(x)=2x-6 and g(x)=x^3 what is (g f)(0)
marin [14]

ANSWER

(g \circ \: f)(0) = - 216

EXPLANATION

The functions are:

f(x) = 2x - 6

g(x) =  {x}^{3}

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

(g \circ \: f)(x) =g(2x - 6)

We substitute f(x) into g(x) to obtain:

(g \circ \: f)(x) =(2x - 6)^{3}

We now substitute x=0 to obtain;

(g \circ \: f)(0) =(2(0) - 6)^{3}

(g \circ \: f)(0) =(- 6)^{3}

This simplifies to:

(g \circ \: f)(0) = - 216
