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!
(Need help ASAP) In a research experiment, the population of a colony of bacteria doubles every hour. The population, f(x), of the colony after x hours can be modeled by the function f(x)=25 ⋅ 2x. What values for the domain are reasonable in the given context?
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
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.
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

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