In Exercises 17-20, find the value of x so that the function has the given value. 17. f(x) = 8x - 7; f(x) = 17
Nastasia [14]

Answer:

17.) x = 3

18.) x = -5

I couldn't do 19.) and 20.) for you because there are weird symbols that I believe you mistakenly input. But I'm sure you now get the gist of how to solve such problems. Peace <3

Step-by-step explanation:

All you really have to do for all of the problems is substitute your value of "x" for the function.

17.) f(x) = 8x - 7; f(x) =17

    17 = 8x -7  ---- substitute 17 for f(x), add 7 on both sides

    24 = 8x ------ divide 8 on both sides

    x = 3

18.)    g(x) = -4x + 7; g(x) = 27

           27  = -4x + 7  substitute 27 for g(x), subtract 7 on both sides

           20 = -4x

            x = -5

F(x) = -3x+17 and g(x) = x^2 -6 find g(5)-f(5)
aniked [119]

Answer:

For the given functions, the value of   g(5)-f(5)  = 17

Step-by-step explanation:

Here, the given functions are:

f(x) =  -3x + 17

g(x) = x ^2 - 6

So, f(5)  = -3(5) + 17

= -15 + 17  = 2

And g(5) = (5)^2  - 6  = 25 - 6  = 19

So, f(5) = 2 and g(5) = 19

⇒g(5) - f(5) =  19 - 2  = 17

Hence, for the given functions, the value of   g(5)-f(5)  = 17

Find the area of a circle with a radius of 3.
TiliK225 [7]

Answer:

A =28.26

Step-by-step explanation:

Using the area formula

A = pi r^2

We use pi = 3.14 and the radius is 3

A = 3.14 * (3)^2

A = 3.14 *9

A =28.26
