If f(x)=8-10x and g(x)=5x+4 what is the value of (fg)(-2)?

1 answer:

6 0

First, calculate f(g(x))==> you plug (5x+4) in the value of x in f(x)

==>f(g(x))= 8-[10(5x+4)===>8-50x-40===>f(g(x))= -50x + 32

& f(g(-2))= -100+32 =68.

There is a mistake in your answers, it should be 68 & not 78

What are the x- and y-intercepts of the graph of 5x-4y= -20

lakkis [162]

To find the intercepts, we can set the opposite variable equal to 0 and solve.

Let's find the x intercept first.

5x - 4(0) = -20

5x = -20

Divide both sides by 5.

x = -4

<h3>The x intercept is -4.</h3>

Now let's find the y intercept.

5(0) - 4y = -20

-4y = -20

Divide both sides by -4.

y = 5

<h3>The y intercept is 5.</h3>

Use the function below to find F(3). <br><br> F(x) = 4(1/3)^x

aalyn [17]

Answer:

4/27

Step-by-step explanation:

F(x) = 4(1/3)^x

Let x =3

F(3) = 4(1/3)^3

Exponents first

F(3) = 4 * 1/27

Then multiply

f(3) = 4/27
