<u>Answer:</u>

The correct answer option is D. $-5^x+3x-2$

<u>Step-by-step-explanation:</u>

We are given the following two functions:

$f(x)=-5^x-4$

and

$g(x)= -3x-2$

We are to find $(f-g)(x)$ so we will subtract the function g from function f, arrange the like terms together and combine them like shown below to get:

$(f-g)(x) =(-5^x-4)-(-3x-2)$

$(f-g)(x)=-5^x-4+3x+2$

$(f-g)(x)=-5^x+3x-2$

Therefore, $(f-g)(x)$ is equal to $-5^x+3x-2$ so the correct answer option is D. $-5^x+3x-2$ .

Help me find the value of x

Sergeu [11.5K]

We know that the entire angle is equal to 90 degrees (look at image below). This means that the sum of 4x-10 and x is 90 degrees, so you can make a formula:

4x - 10 + x = 90

Now you can solve for x

5x - 10 = 90

5x = 100

x = 20

Hope this helped!
