If f(x)= 5x+4 and g(x)= -2+1...... 1) f(6) + g(-8) = ? 2) g(4)= ? 3) f(-2)= ? PLZ PLZ PLZ HELP ME I AM SOOOOO CONFUSED!!!!!!!!!!

Answer:

See below.

Step-by-step explanation:

So we have the two functions:

$f(x)=5x+4\text{ and } g(x)=-2x+1$

First, find the values of each function:

$f(x)=5x+4\\f(6)=5(6)+4\\f(6)=30+4=34$

$g(x)=-2x+1\\g(-8)=-2(-8)+1\\g(-8)=16+1=17$

Therefore:

$f(6)+g(-8)\\=(34)+(17)=51$

Plug in the number into the function:

$g(x)=-2x+1\\g(4)=-2(4)+1=-8+1=-7$

Like the last one:

$f(x)=5x+4\\f(-2)=5(-2)+4=-10+4=-6$

What is the radius of f?

Mazyrski [523]

This is a simple right triangle problem.
a^2 + b^2 = c^2

the hypotenuse (or c) is 9 +x
and a is x
And b is 15

So so we sub in the values
x^2 + (15)^2 = (9+x)^2

x^2 + 225 = x^2 + 18x + 81
144 = 18x
8 = x
