Answer:

f(x)=14

Step-by-step explanation:

First, you simply plug in x=2 into f(x)=7x

Therefore you are left with f(x)=7(2)

Then you must notice that parenthesis mean multiplication...

And.. 7 x 2 =14

Hence your answer of f(x)=14

Kesia knows that 1/4=0.25. Explain how she could use this fact to determine the decimal equivalent of 5/8
STatiana [176]
She knows that
0.25 =  \frac{1}{4}  =  \frac{2}{8}
\frac{5}{8}  =  \frac{2}{8}  +  \frac{2}{8}  +  \frac{1}{8}  = \\ 0.25 + 0.25 +  \frac{0.25}{2} =   \\ 0.25 + 0.25 + 0.125 = 0.625

Convert the following equation to slope-intercept form to graph. 7x – y = –3
jekas [21]
Slope-intercept form:
y = m x + b
7 x - y = - 3
- y = - 7 x - 3  /  * ( - 1 )( we have to multiply both sides of the equation by - 1 )
Answer:
y = 7 x + 3

Help please i dont get it
ale4655 [162]

Answer:

  (c)  x = 2 and x = -8

Step-by-step explanation:

The rules of logarithms let you rewrite this as a quadratic equation. That equation will have two (2) potential solutions. We know from the domain of the log function that any negative value of x will be an extraneous solution.

__

The rules of logarithms that apply are ...

  \log(a)+\log(b)=\log(ab)\qquad\text{all logarithms to the same base}\\\\\log_b(a)=c\ \Longleftrightarrow\ b^c=a\\\\

__

<h3>take antilogs</h3>

We can rewrite the equation so that only one logarithm is involved. Then we can take antilogs.

  \log_4(x)+\log_4(x+6)=2\\\\\log_4(x(x+6))=2\qquad\text{using the first rule}\\\\4^2=x(x+6)\qquad\text{using the second rule}

__

<h3>solve the quadratic</h3>

Adding (6/2)² = 9 to both sides will "complete the square."

  16 +9 = x² +6x +9 . . . . . . . add 9

  25 = (x +3)²

  ±√25 = x +3 = ±5 . . . . . take the square root(s)

  x = -3 ±5 = {-8, +2}

The two potential solutions are x = 2 and x = -8.
