Answer:

a) 3x - 1

Step-by-step explanation:

f(x) + g(x)

(-2x + 6) + (5x - 7)

Drop the parentheses

-2x + 6 + 5x -7

5x and -2x can be combined as well as 6 and -7

So, 3x -1

write an absolute value equation to calculate the distance between the two points (4, -2) and (-9, -2)
meriva

9514 1404 393

Answer:

  d = |-9-4| = 13

Step-by-step explanation:

The y-values are the same for the two points, so the distance between them on that horizontal line is the difference of x-values.

  d = |(-9) -(4)|

  d = |-13| = 13

The distance between the points is 13 units.

Find the length of . Use that length to find the length of .
Verdich [7]

Answer:

Length of CD is 10.7 cm

Step-by-step explanation:

we are given to find length of CD

Calculation of CD:

Firstly, we will find AC

In triangle ABC, we can use trig

sin(30)=\frac{AC}{10}

AC=10sin(30)

AC=5

now, we can find CD

In triangle ACD , we can use trig

cot(25)=\frac{CD}{AC}

CD=ACcot(25)

now, we can plug AC=5

CD=5cot(25)

CD=10.7

Answer:

  • vertical shift: 7 (up)
  • horizontal shift: 2 (right)
  • vertical asymptote: x=2
  • domain: x > 2
  • range: all real numbers

Step-by-step explanation:

For any function f(x), the transformation f(x -h) +k represents a horizontal shift of h units to the right and k units upward.

Here, the parent function is log₂(x) and the transformation to log₂(x -2) +7 represents translation 2 units right and 7 units upward.

The parent function has a vertical asymptote at x=0, so the shifted function will have a vertical asymptote at x-2=0, or x = 2.

The parent function has a domain of x > 0, so the shifted function will have a domain of x-2 > 0, or x > 2.

The parent function has a range of "all real numbers." Shifting the function vertically does not change that range. The range of the shifted function is still "all real numbers."

The graph is shown below. The vertical asymptote is the dashed orange line.

_____

The "work" is in matching the pattern f(x -h) +k to the function log₂(x -2) +7.
