What is the x-value of the solution to this system of equations?
3x + 2y = 7
y = –3x + 11
a. 6
b. 3
c. -4
d. 5
Step-by-step explanation:
3x+2y = 7
3x +2(-3x+11) = 7
3x-6x +11 = 7
-3x+11 =7
-3x = 7-11
-3x =-4
x =-4/-3
x = 4/3.

Your answer: 3^3 + 3(4 + 1/3) = 40
Answer: 130
Step-by-step explanation: I first did 4+1/3 which is 4 1/3 and then I did 3^3 which is 27 then I added 3 to 27 and I multiplied 27 and 4 1/3 and got 130.
What generalization can you make about the equations?Use the drop-down menus to complete the explanation
Answer:
They have the same end results
Step-by-step explanation:
Given
The missing equations are:
[tex]7 / \frac{1}{4} =[/tex]
[tex]7 * 4 =[/tex]
Required
Make a generalization about the equations
First, we solve both equations.
(1)
[tex]7 / \frac{1}{4} =[/tex]
[tex]7 / \frac{1}{4} = 7 * 4[/tex]
[tex]7 / \frac{1}{4} = 28[/tex]
(2)
[tex]7 * 4 =[/tex]
[tex]7 * 4 = 28[/tex]
From the solutions to the above equations, we can see that both equations have the same end result;
i.e.
[tex]7 / \frac{1}{4} = 7 * 4 = 28[/tex]
Hence;
A generalization can be: "they have the same end results"

Help pls! (4c+4)(2c-3)
Answer:
8c2 - 4c - 12
Step-by-step explanation:
Answer:
8c^2-4c-12
Step-by-step explanation
So you have to multiply 4c into 2c and -3 first and then 4 into 2c and -3.
(4c+4)(2c-3)
4c X 2c is 8c^2
(4c+4)(2c-3)
4c X -3 is -12c
So for the 4c multiplying in you would get 8c^2 and -12c, but we still have to multiply in the 4
4 X 2c is 8c
(4c+4)(2c-3)
4 X -3 is -12
So then we would get 8c^2-12c+8c-12, however we can still combine the -12c and the 8c. Combining those would get -4c. So the final answer is 8c^2-4c-12
A circular flower bed in Kay's backyard has a diameter of 8 feet. what is the area of the flower bed? round your answer to the nearest tenth.
Answer:
16pi or 50.2
Step-by-step explanation:
formula for area of a circle is pi * radius squared. Since the diameter is 8 you divide that by 2 to get 4 and you square it so it becomes 16. Then you multiply it by pi or 3.14 to get 50.24 and then you round.

Sam charges a $5 travel free and then 3.25 per hour for labor. How many hours will he need to work yo make $18.
The number of hours he need to work is 4.
Given that,
Sam charges a $5 travel free and then 3.25 per hour for labor. The earnings is $18.Here we assume the no of hours be x.
Based on the above information, the calculation is as follows:
5 + 3.25x = 18
3.25x = 18 - 5
3.25x = 13
x = 4

Question 10 options:
A marine biologist is researching the population density of dolphins. The marine biologist counts 175 dolphins within a radius of 2.5 miles of a half-circle off of Clearwater Beach.
What is the population density of the dolphins?
Use 3.14 for pi, and round to the nearest whole number.
Answer:
Density = 9 dolphins / mi^2 This is the result.
Step-by-step explanation:
Number of dolphins = 175
Radius = 2.5 mi
1. - Calculate the area
Area = pi* r^2
Area = 3.14*2.5^2
Area = 3.14*6.25
Area = 19.625 mi^2
2. - Calculate the density
density = dolphins/mi^2
- Substitution
density = 175 / 19.625
Result
density = 8.9 dolphins/mi^2
Rounding to the nearest whole number
Density = 9 dolphins / mi^2
Answer:
Area of half circle = 1/2 x π x r^2
= 1/2 x 3.14 x 2.5^2
= 9.8125 miles²
For the density divide the number of dolphins by the area:
Density =population/area= 175/9.8125 = 17.83 dolphins/mile²
the population density of the dolphins is 18dolphin/miles²
If g(x) is the inverse of f(x) and f(x) = 4x+12, what is g(x)?
