Answer:
Following on from step 3
0 = (x + 1)(x + 3)
equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x + 3 = 0 ⇒ x = - 3
Substitute these values into either of the 2 equations for the corresponding value of y
using y = 2x + 11
x = - 1 : y = - 2 + 11 = 9 ⇒ (- 1, 9 )
x = - 3 : y = - 6 + 11 = 5 ⇒ (- 3, 5 )
solutions are (- 3, 5 ) and (- 1, 9 ) <<<<<<< CORRECT
Step-by-step explanation:
The solutions that represents the system of the equation are (- 3, 5 ) and (- 1, 9 )
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
0 = (x + 1)(x + 3)
By equating each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x + 3 = 0 ⇒ x = - 3
Substitute these values in 2 equations for the corresponding value of y
using y = 2x + 11
x = - 1
y = - 2 + 11 = 9 ⇒ (- 1, 9 )
x = - 3
y = - 6 + 11 = 5 ⇒ (- 3, 5 )
Therefore, the solutions are (- 3, 5 ) and (- 1, 9 )

Quinn has 6 bottles of water that each weigh \large \frac{3}{5} pound. What is the total weight of the water bottles?_
Quinn has 6 bottles of water that each weigh \large \frac{3}{5} pound. What is the total weight of the water bottles?
Answer:
3.6 pounds
Step-by-step explanation:
If 1 bottle weighs 3/5 pounds
the 6 bottles will weigh 6 x 3/5
= 18/5
ratio method :
1:3/5
6:x
since the ratios are direct we can cross multiply
18/5 = 1x
so the 6 bottles weigh 18/5 pounds or 3.6 pounds

Solve for n.
–2(n + 2) + 6 = 8
n =
Answer:
n = -3Step-by-step explanation:
Answer:
n = -3
Step-by-step explanation:
We have the equation –2(n + 2) + 6 = 8. First, we simplify it:
–2(n + 2) + 6 = 8
–2(n + 2) = -2n + (-4) = -2n - 4
So now we have:
-2n - 4 + 6 = 8
We can subtract 6 from both sides of the equation to get:
-2n - 4 = 2
We can also add 4 to both sides to get:
-2n = 6
Divide both sides by 2 to get:
-n = 3
Multiply both sides by -1 to get:
n = -3

B. 7 in., 17 in., 11 in.
C. 9 m, 12 m, 14 m
D. 11 ft, 60 ft, 61 ft
Answer:
D. 11 ft, 60 ft, 61 ft
Step-by-step explanation:
By using the Pythagorean Theorem, a^2 + b^2 = c^2, we figure out theat 11^2 + 60^2 = 61^2. 11^2 + 60^2 = 61^2, 121 + 3600 = 3721, 3721 = 3721, so option D

The middle value of the ordered data set is 7.
The value that occurs most often in the set is 7.
The difference between the smallest value and the largest value is 7.
The sum of all the data values divided by the number of data values is 7.
Answer:
The sum of all the data values divided by the number of data values is 7.
Explaination:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
Answer:
The last one
Step-by-step explanation:
We know that the mean is 7, what we are trying to identify is which situation correctly describes how to find the mean.
Define
Mean = Sum of values divided by number of data values
Reasoning
For "The middle value of the ordered data set is 7."
The middle value is known as the median not mean therefore this answer is not correct.
For "The value that occurs most often in the set is 7."
The number that occurs the most is known as the mode not the mean therefore this is not the correct answer
For " The difference between the smallest value and the largest value is 7.
"
The difference between the smallest and largest number is known as the range therefore this answer is not correct.
We're left with "The sum of all the data values divided by the number of data values is 7." which does indeed correctly describe how to find the mean.
