evaluate 7y-3y for y=2

Answers

Answer 1

Answer:

8

Step-by-step explanation:

So. Let's plug in 2 for y. 7(2)-3(2). Before we subtract, let's multiply first. 7 times 2 is 14 and 3 times 2 is 6. So now the equation looks like this: 14-6. From here, you do regular subtraction to get 8. Hope this helps!

If ∠ G is supplementary to ∠ H and the measure of ∠ G is 65 ° what is the measure of ∠ H ?
Please help

Answers

Supplementary angles add up to = 180 degrees...so G + H = 180. To find H, subtract G from 180.
180 - 65 = 115
So angle H = 115 degrees

Measure of ∠H = 115°

What are supplementary angles?

Two angles are called supplementary when sum of their measures is 180 degrees.

Given,

∠G is supplementary to ∠H

∠G is 65 °

∠G + ∠H = 180°

65° + ∠H = 180°

∠H = 180° - 65°

∠H = 115°

Hence, 115° is measure of ∠H .

1. all real numbers



2. all real numbers greater than 0



3. all real numbers greater than or equal to 0



4. all real numbers greater than or equal to 25

Answers

Answer:

Step-by-step explanation:

The answer is 3

The reasonable domain is all real numbers greater than or equal to 0.

What is domain?

The collection of all conceivable independent values that a function or relation may take is known as its domain.

Given:

In a research experiment,

the population of a colony of bacteria doubles every hour.

Here, we can use exponential growth function.

The population, f(x), of the colony after x hours can be modeled by the function f(x)=25 ⋅ 2ˣ.

The value of x can not be negative because it represents time.

The domain of the function is all achievable values.

So, the domain is  all real numbers greater than or equal to 0

Therefore, the domain is all real numbers greater than or equal to 0.

Can someone please tell me the degree measure of angles 1,2 3 and 4?
It’ll help even more if you explain.

Answers

Answer:

angle 1 is 42

angle 2 is 138

angle 3 is also 42

Step-by-step explanation:

for angle 1, I don't remember what the exact rule was but basically since they are opposite of each other they are equal

for angle 2 all you have to do is subtract 42 from 180 because line n is at an angle of 180 and line m simply splits it into two pieces

for angle 3, I dont remember what the exact rule is or hot to explain it well but it is also 42
