<h3>Answer:    -49k - 10</h3>

==================================================

Work Shown:

7(-2-7k) + 4

7(-2) + 7(-7k) + 4

-14 - 49k + 4

-49k + (-14+4)

-49k - 10

In the second step, I distributed the outer 7 to each term inside. From there, I grouped and combined like terms, which were the -14 and 4.

Hey there! I'm happy to help!

We start out with 3.

3

Our mom gives us 10.

3+10=13

Our dad gives us 30.

13+30=43

Our aunt and uncle give us 100.

43+100=143

And we have another 7.

143+7=150

Therefore, we have $150 now.

Have a wonderful day! :D

Use the definition of the logarithmic function to find x. log4 0.25=x x=?
GREYUIT [131]
The answer is -1.

log_4(0.25)  =log_4( \frac{1}{4})= log_4(4^{-1} ) \\  \\ &#10;log(x^{a} ) = a*log(x) \\  \\ &#10;log_4(4^{-1} )= -1 *log_4(4) \\  \\ &#10;log_y(x) =  \frac{log(x)}{log(y)}  \\  \\ &#10;-1 *log_4(4) = -1* \frac{log(4)}{log(4)} = -1

If P is the midpoint of XY, XP = 8x - 2 and PY = 12x - 30, find the<br> value of x.
Arlecino [84]

Answer:

x=7

Step-by-step explanation:

<u>If P is the midpoint of XY, then XP = PY:</u>

  • 8x - 2 = 12x - 30
  • 12x -8x = 30 -2
  • 4x = 28
  • x= 28/4
  • x= 7

A truck is said to get 18 miles per gallon on a highway, but this value can fluctuate,
Ratling [72]

Answer: 14 miles ≤ D ≤ 22 miles.

Step-by-step explanation:

The mean distance traveled per gallon, is 18 miles.

But this can fluctuate, at most, by 4 miles.

Because we have here the "at most", we know that we should use the ≤, ≥ symbols.

Then, if the mean is 18mi, the range of possible distances traveled per gallon is:

(18 miles - 4 miles) ≤ D ≤ (18 miles + 4 miles)

Where D is the distance.

14 miles ≤ D ≤ 22 miles.

So the truck can get between 14 miles and 22 miles per gallon on the highway.
