HELP PLEASE! What’s the domain and range?

Answers

Answer 1

Answer:

Domain → (-∞, -1)∪(-1, ∞)

Range → (-∞, ∞)

Step-by-step explanation:

Given function is,

[tex]\frac{f(x)}{g(x)}=\frac{x^2+2x-5}{2x+2}[/tex]

This function is not defined when the denominator is zero.

2x + 2 = 0

2x = -2

x = -1

Therefore, x = -1 is not in the domain of this function.

And the domain will be,

(-∞, -1)∪(-1, ∞)

For all values of x (except x = -1) we get some output values (value of [tex]\frac{f(x)}{g(x)}[/tex]).

Therefore, range of the function will be (-∞, ∞).

find the value of x.

Answers

Answer: x = 20

Steps:
5x = 100°
x = 100/5
x = 20

So these are vertical angles (share a vertex) which means they are the same measure. Set them equal to each other to find x

[tex](5x) = 100[/tex]

[tex]\frac{5x}{5} = \frac{100}{5}[/tex]

[tex]x = \frac{100}{5}[/tex]

Answer:

[tex]x = 20[/tex]

People use water to cook, clean, and drink every day. An estimate of 33.9% of the water used each day is for cooking. If a family uses 67.8 gallons of water a day for cooking, how many gallons do they use every day?

Answers

Answer:

23 gallons of water

Step-by-step explanation:

This is calculated as:

33.9 % × 67.8 gallons of water

= 0.339 × 67.8 gallons of water

= 22.9842 gallons of water

Approximately = 23 gallons of water

Therefore, 23 gallons of water are used everyday for cooking
