If a term doesn't have a coefficient , it is considered that the coefficient is 1
1x+6x
Collect like terms by adding their coefficients
(1+6)x
Add the numbers
7x
1+6=7
To add the numbers using a number line, start from zero.
Since 1 is positive, move the point 1 unit to the right.
Since 6 is positive, move the point 6 units to the right
The result is 7

The population of pine bluff is 6791 and is decreasing at a rate of 7 per year.Write the linear equation that models this situation.
Answer:
y=15x+10
Step-by-step explanation:
The linear equation that models the situation is y = 6791 - 7x.
What is the slope-intercept form of a line?The slope-intercept form of a line is y = mx +c where m is the slope of the line and c is the y-intercept
Given that, the population of pine bluff is 6791 and decreasing at a rate of 7 per year.
The population after x year is:
6791 - 7x
Now, if the population after x year is represented by y, then the equation is:
y = 6791- 7x
Hence, the linear equation that models the situation is y = 6791 - 7x.

A.there is no correlation
B.there is a correlation between amount of time spent playing video games and memorization ability.there is probably also causation.this is because there is an increase in memorization ability with a decrease in the amount of time spent playing video games.
C.there is a correlation between amount of time spent playing video games and memorization ability.there may or may not be causation.further studies would have to be done to determine this
Answer:
There is a correlation between amount of time spent playing video games and memorization ability. There may or may not be causation. Further studies would have to be done to determine this.
Step-by-step explanation:
A piano instructor examined student progress. She noticed that when students spend less time playing video games, their memorization ability tends to increase. What can she conclude?
There is a correlation between amount of time spent playing video games and memorization ability. There may or may not be causation. Further studies would have to be done to determine this.
The piano instructor observes changes in the number of video games
played and its effects on the memorization ability.
What she can conclude is; A. There is no correlationReasons:
The aim of the experiment is to check if there is a correlation between the
time students spend playing video games and their memorization ability.
The observation made following a reduction in the time the student spend
playing video games and their memorization ability is that there is no
change in the memorization ability of student following a change in the
time spent playing video games.
The conclusion that can be made is that there is no relationship between
the time the student spends playing video games and their memorization
ability.
The time spent playing video game and memorization are not correlated.
Therefore, the correct option is; A. there is no correlationLearn more about correlation here:

Find the GCF of 29 and 18
Answer:
1
Step-by-step explanation:
The greatest common factor of two numbers is the largest number that both can divide into.
29 is a prime number. This means that it is only divisible by 1 and itself.
18 has the factors 1,2,3,6,9,18.
Only the number 1 is a shared factor between the two numbers, therefore 1 is the greatest common factor of 29 and 18.
Hope this helped!
Answer:
1
Step-by-step explanation:
29 is a prime number. Hence, the GCM of a number x and 29 is 1 if x isn't divisible by 29. Because 18 isn't divisble by 29, the GCM of 18 and 29 is 1.

Benito drew a graph representing the number of miles he ran and the number
calories he burned. What is the unit rate in calories per mile? 3 4 250 1,000
Answer:
250
Step-by-step explanation:
1000 divided by 4, is 250
The unit rate would be 250 calories per mile which is the slope of the given linear function.
What is the unit rate?The unit rate of a linear function is defined as the slope of the linear function.
The slope is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
The given graph represents the number of miles he ran and the number of calories burned.
Taking two points as per the given graph :(2, 500), (6, 1500)
Let
x₁ = 2, y₁ = 500
x₂ = 6, y₂ = 1500
Substitute values in the formula to get
unit rate = (1500 - 500)/(6 - 2)
unit rate = (1000)/(4)
Apply the division operation,
unit rate = 250
Therefore, the unit rate would be 250 calories per mile

Mike hosted a fundraiser to benefit the children's hospital and the cancer society twenty people came and each paid 30 to enter the event an additional 800 was raised before the event
A) write a number expression to represent the total amount of money raised. Find the value of your expression.
B) mike split the money equally between the two organizations. How much did each organization receive?
PLEASE HELPPP
Answer:
Step-by-step explanation:
We know 20 people attended and each paid $30. There was already $800 before the event.
A)
T = total amount raised
p = number of people that attended
T = 30p + 800 $30 multiplied by the number of people who attended
T = 30(20) + 800 gives the amount raised at the fundraiser. We add 800
T = 600 + 800 because that was raised before the event.
T = $1400
B) If he split the money equaly between 2 organizations, we divide the total raised, T, by 2.
$1400/2 = $700 Each organization recieved $700

Pattie's Produce charges $2.29 for a package of strawberries. On average, Pattie's Produce sells 95 packages of strawberries daily. They estimate that for each 20-cent increase in the cost of a package of strawberries, 9 less packages will be sold each day. Let x represent the number of 20-cent increases in the cost of a package of strawberries.
Answer:
-1.8x² - 1.61x - 37.45 > 0
Step-by-step explanation:
Pattie's Produce charges $2.29 for a package of strawberries. On average, Pattie's Produce sells 95 packages of strawberries daily. They estimate that for each 20-cent increase in the cost of a package of strawberries, 9 less packages will be sold each day. Let x represent the number of 20-cent increases in the cost of a package of strawberries. Which inequality represents the values of x that would allow Pattie's Produce to have a daily revenue of at least $255 from selling the packages of strawberries?
Answer:
The cost of packaging 95 packages of strawberries is $2.29(95)=$217.55.
20-cent increase in the cost of a package of strawberries leads to 9 less packages to be sold. If x represent the number of 20-cent increases in the cost of a package of strawberries. the cost of packaging is:
Cost = (2.29 + 0.2x)(95 - 9x)
For a revenue of atleast $255:
(2.29 + 0.2x)(95 - 9x) > 255
217.55 - 20.61x + 19x - 1.8x² > 255
-1.8x² - 1.61x + 217.55 > 255
-1.8x² - 1.61x + 217.55 - 255 > 0
-1.8x² - 1.61x - 37.45 > 0
