What is the domain of the function f(x)= √x+6-7

Tatiana [17]

Answer:

x≥1

Step-by-step explanation:

f(x) = √x+6-7

f(x) = √x-1

The value under a square root must be non-negative; therefore make the inequality x-1 ≥ 0 and solve it.

x ≥ 1

There's your domain! Hope this helps! :D

Two angles are complementary. One angle is labeled 2p+6°. The other angles is labeled 4p°. Find the value of p.

makkiz [27]

Answer:

Value of p is 14

Step-by-step explanation:

$given \: complementary \: angles \: add \: up \: to \: 90 \: degrees \\ then \\ 2p + 6 + 4p = 90 \\ 6p + 6 = 90 \\ 6(p + 1) = 90 \\ p + 1 = \frac{90}{6} \\ p + 1 = 15 \\ p = 15 - 1 \\ p = 14$

HAVE A NICE DAY!

Given that two sides of a triangle have sides 5 and 7, write the range of the lengths of the third side:

matrenka [14]

Answer:

Step-by-step explanation:

The two sides add up to 12. If the third "side" of the triangle is 12, then 5 and 7 will lie horizontally on 12.

So the maximum value must be less than 12. What's the smallest x could be?

well 5 + something must be > than 7. If they are not larger than 7, then 5 and something will lie on 7 just as it did before. So how big is something?

5 + y > 7

5 - 5 + y > 7 - 5

y > 2

So the range is 2 < x < 12

How else could you write this?

2 < x

x < 12 is one way.

On a piece of paper, graph y + 2 ≤ -2/3x +4. Then determine which answer choice matches the graph you drew.

koban [17]

Answer:

Step-by-step explanation:

You only need to look at the comparison symbol (≤) to determine the correct graph. It tells you the shading is below the boundary line, and the boundary line is included in the solution region (a solid line).

The shading is below the line because y-values are less than (or equal to) values on the line.

Choice B matches the attached graph.
