F(x) = x^2-5 g(x) = 4x - 4 Find (f-g) (5)

Tresset [83]

Answer:

The correct answer option is: 4.

Step-by-step explanation:

We are given the following two functions and we are to find the value of $( f - g ) ( 5 )$ :

$f(x) = x^2 - 5$

$g(x) = 4x - 4$

Finding $( f - g ) ( x )$ :

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

$( f - g ) ( x ) = x^2-4x-1$

So, $( f - g ) ( 5 ) = (5)^2-4(5)-1 = 4$

Help a b c or d with one

prisoha [69]

Hello!

We know that angle AOC = 79 degrees, AOB = 4x - 15, and BOC = 2x+10. If you observe the picture, you can notice that the two other angles make up AOC.

Therefore, the measure of AOC = the measure of AOB + the measure of BOC. Now, we can create our equation with this info.

79 = (4x - 15) + (2x + 10)

Now, simplify.

79 = 4x - 15 + 2x + 10

79 = 6x - 5

84 = 6x

x = 14

Now, to find the individual degree measurements, substitute in 14 for x and solve.

AOB: 4x - 15 = 4(14) - 15 = 56 - 15 = 41 degrees

BOC: 2x + 10 = 2(14) + 10 = 28 + 10 = 38 degrees

Therefore, your answer is B, BOC = 38 degrees and AOB = 41 degrees.

Hope this helps!
