Find f +g, f – 9, fg and. Determine the domain
for each function.
f(x) = 3x – 4, g(x) = x + 2
Answers
Step-by-step explanation:
f(x) = 3x - 4
g(x) = x + 2
(f + g) = f(x) + g(x)
= 3x - 4 + x + 2
= 4x - 2
Domain: All real numbers
(f - g) = f(x) - g(x)
= 3x - 4 - (x + 2)
= 3x -4 -x -2
= 2x -6
Domain: All real numbers
(fg) = f(x) * g(x)
= (3x - 4)(x + 2)
= 3x^2 + 6x -4x -8
= 3x^ 2 + 2x - 8
Domain: All real numbers

Ella takes hours to complete a painting. Holly takes of the time that Ella takes. How long will Holly take to complete 5 paintings
Answers
Answer:
6 hours
Step-by-step explanation:
Ella takes 1 3/5 hours to complete a painting. Holly takes 3/4 of the time that Ella takes. How long will Holly take to complete 5 paintings?
Ella =1 3/5 hours = 8/5 hours
Holly = 3/4 of 8/5 hours
= 3/4 × 8/5
= (3*8)/(4*5)
= 24/20
= 6/5 hours
Number of hours : number of painting = 6/5 hours : 1 painting
How long will Holly take to complete 5 paintings
Let x = number of hours
Number of hours : number of painting = x hours : 5 painting
6/5 hours : 1 painting = x hours : 5 painting
6/5 ÷ 1 = x ÷ 5
6/5 × 1/1 = x / 5
6/5 = x / 5
Cross product
6 * 5 = 5 * x
30 = 5x
x = 30/5
x = 6 hours
It will take Holly 6 hours to complete 5 paintings

Answer:
D = 31
Step-by-step explanation:
Consider the equation showing the distributive property.
84 +93 = 3 (28+ D)
The unknown value we are asked to find is D
Hence:
84 + 93 = 84 + 3D
Collect like terms
84 - 84 + 93 = 3D
93 = 3D
D = 93/3
D = 31
Therefore, the unknown value that would make the equation true is 31

Over the last three evenings, Ivanna received a total of 116 phone calls at the call center. The third evening, she received 4 times as many calls as the first
evening. The second evening, she received 10 fewer calls than the first evening. How many phone calls did she receive each evening?
Answers
Answer:
first evening = 21 phone calls
second evening = 11 phone calls
third evening = 84 phone calls
Step-by-step explanation:
Total phone calls = 116
Let
Number of calls in the first evening = x
The second evening = x - 10
The third evening = 4x
Total phone calls = first evening + second evening + third evening
116 = x + (x - 10) + 4x
116 = x + x - 10 + 4x
116 + 10 = 6x
126 = 6x
x = 126 / 6
x = 21 phone calls
Number of calls in the first evening = x
= 21 phone calls
The second evening = x - 10
= 21 - 10
= 11 phone calls
The third evening = 4x
= 4(21)
= 84 phone calls

Sarah has built a scale model of a bridge. The real bridge is 56 ft across and 21 ft wide. Sarah's model is 8 in. across and
2.5 in. wide. Is Sarah's model a true model of the bridge? Explain.
Answers
Answer:
Well, there are 12 inches ina foot so let's multiply 56 by 12. Now, divide 672 by 8: 672/8 = 84 So, we have 84 which means that if we multiply 84 by 2.5 it should equal however many inches there are in 21, if it is to be a true scale model. It is not equal, so no, it is not a true scale model.
Step-by-step explanation:
HOPE THIS HELPS!!!
BRAINLIEST PLZ???
Answer:
It is not equal, so no, it is not a true scale model.
Step-by-step explanation:
Well, we need to find the ratio of it and see if both measurements of the 'scale' model are the same. But before we do, take in mind we can't divide 56/8 because 56 needs to be converted into inches.
56 • 12 = 672
divide 672 by 8:
672/8 = 84
So, we have 84 which means that if we multiply 84 by 2.5 it should equal however many inches there are in 21, if it is to be a true scale model
21 • 12 = 252
2.5 • 84 = 210
It is not equal, so no, it is not a true scale model.

A person earns $17,300 one year and gets a 5% raise in salary. Calculate the new yearly salary using a percent greater than 100.
Answers
Answer: $18,375
Step-by-step explanation:
The person was earning $17,300 and got a 5% raise.
The $17,300 represents 100% of itself. If it were to increase by 5% therefore, the new salary would be: 100 + 5 = 105%
The new salary would be 105% of $17,300.
= 17,300 * 105%
= 17,500 * 105/100
= $18,375

In a sale normall prices are reduced by 10% Natalie brought a pair of shoes from the sale and they cost £54 what was the original price
Answers
Answer: £60
Step-by-step explanation:
Natalie bought a pair of shoes for £54 which had been reduced by 10%.
To find the original cost, assume the original cost is x.
The discount would be: 10% * x
The expression would therefore be:
x - (10% * x) = 54
x - 0.1x = 54
0.9x = 54
x = 54 / 0.9
x = £60
Choose the correct algebraic equation to represent: the amount decreased by $9 is $42.
Giving brainlist please help!
9 - m
9 – m = 42
m - 9
m – 9 = 42
Answers
m - 9 = 42
42 is our final answer so that should be by itself.
If something is being decreased by 9, that means that we are taking away 9 from something so it should be m - 9.
Answer:
m-9=42
Step-by-step explanation:
I'm pretty sure that m-9=42 is the correct answer because m or the amount is being decreased by 9 as 9 is being subtracted from it.

A. 2
B.3
C
[tex] \sqrt{4} [/tex]
D
[tex] \sqrt{8} [/tex]
Answers
Answer:
D
Step-by-step explanation:
We want to find the distance between (-6, 4) and (-8, 6).
We can use the distance formula given by:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Let (-6, 4) be (x₁, y₁) and let (-8, 6) be (x₂, y₂).
Substitute:
[tex]d=\sqrt{(-8-(-6))^2+(6-4)^2[/tex]
Evaluate:
[tex]d=\sqrt{(-2)^2+(2)^2[/tex]
Evaluate:
[tex]d=\sqrt{4+4}=\sqrt{8}[/tex]
Hence, our answer is D.
