Answer:

Step-by-step explanation:

I believe the answer to this is one. A numerical coefficient is a constant multiplier of the variables in a term. Since the term is only an x, you always put a one before an x. Therefore, the numerical coefficient is 1.

Answer this question

Answer: OPTION B.

Step-by-step explanation:

We have the following functions f(x) and g(x):

$f(x)=x^2-2x-8\\\\g(x)=\frac{1}{4}x-1$

In order to find for which values of "x" $f(x)=g(x)$ , we can check each option given:

OPTION A

Substitute $x=-1.75$ into the function f(x) and evaluate:

$f(-1.75)=(-1.75)^2-2(-1.75)-8=-1.4375$

Substitute $x=-1.75$ into the function g(x) and evaluate:

$g(-1.75)=\frac{1}{4}(-1.75)-1=-1.4375$

Substitute $x=-1.438$ into the function f(x) and evaluate:

$f(-1.438)=(-1.438)^2-2(-1.438)-8=-3.0561$

Substitute $x=-1.438$ into the function g(x) and evaluate:

$g(-1.438)=\frac{1}{4}(-1.438)-1=-1.3595$

This is not the correct option.

OPTION B

We already know that:

$f(-1.75)=-1.4375$

$g(-1.75)=-1.4375$

Substitute $x=4$ into the function f(x) and evaluate:

$f(4)=(4)^2-2(4)-8=0$

Substitute $x=4$ into the function g(x) and evaluate:

$g(4)=\frac{1}{4}(4)-1=0$

This is the correct option.

OPTION C

We already know that:

$f(-1.438)=-3.0561$

$g(-1.438)=-1.3595$

Therefore, this is not the correct option.

OPTION D

We already know that:

$f(4)=0$

$g(4)=0$

Substitute $x=0$ into the function f(x) and evaluate:

$f(0)=(0)^2-2(0)-8=-8$

Substitute $x=0$ into the function g(x) and evaluate:

$g(0)=\frac{1}{4}(0)-1=-1$

This is not the correct option.

5/9 - 1/3•1/6 Show work

gavmur [86]

- First multiply 1/3 times 1/6 across giving you 1/18

-then get the LCD of 5/9 and 1/18 which is 18
multiply 5/9 times 2/2 to get 10/18.

-Now you can subtract
10/18- 1/18 = 9/18

-further simplify by diving the top and bottom of 9/18 by 9
the answer would be =1/2

*Note: you do not need to get the LCD of a fraction when multiplying or dividing. You DO need the LCD when adding or subtracting a fraction.
