Answer:
See below:
Step-by-step explanation:
No, it appears to be incorrect if its based off the image you have provided.
I can help you make it correct though.
I'll take you through 2 steps to solve the problem, one being Equations and another being Graphing.
Equations
So, to find the slope, we need to get an equation. Most slope's are in the [tex]y=mx+b[/tex] form which have a few components that we need to know to figure it out.
[tex]m[/tex] is the slope of the line.[tex]b[/tex] is the y intercept: (0,b)Now that we know this, we can start breaking i down and soon begin graphing.
The y intercept is one point that we can use to start the line, as the question says to graph the line, we need to start by using the y intercept as one point on the line which would be (0,6) so that would be one point.
Graphing
To graph the line, we need to find the y intercept and another point. For example, we found the y intercept in the previous section, and it was (0,6). We can find another point by just looking at the slope. The slope of the line is 3 so we would go up 3 right 1 from our point to get our second point.
So, our points would be:

Find the perimeter. Simplify your answer.
Answer:
[tex]18x+32[/tex]
Step-by-step explanation:
Perimeter is the total distance around a shape and can be found by calculating the sum of a shape's sides.
In this case, we are given a parallelogram, a quadrilateral with two pairs of parallel sides. Thus, the formula for a parallelogram's perimeter is as follows:
[tex]P=2(a+b)[/tex]
Substitute the variables in the formula for the expressions on the parallel lines:
[tex]a=3x+6[/tex]
[tex]b=6x+10[/tex]
[tex]P=2(3x+6+6x+10)[/tex]
Distribute the 2 into each term:
[tex]P=6x+12+12x+20[/tex]
[tex]P=18x+32[/tex]
Answer:
18x + 32Step-by-step explanation:
Perimeter = 3x + 6 + 6x + 10 + 6x + 10 + 3x + 6
= 18x + 32...ans

Solve for bb.
42=42+9b
Answer:
0
Step-by-step explanation:
42=42+9b
We move all terms to the left:
42-(42+9b)=0
We add all the numbers together, and all the variables
-(9b+42)+42=0
We get rid of parentheses
-9b-42+42=0
We add all the numbers together, and all the variables
-9b=0
b=0/-9
b=0
Find the values of x and y
Answer:
X=20
Y=70
Step-by-step explanation:
All angles within a triangle add up to 180
180 - 40 = 140
140 is the top angle of the big triangle
140 + x + x = 180
x = 20
Now use x to find y by subtracting from the right angle (90 degrees)
90 - 20 = 70
70 + 40 + y = 180
Y = 70
(5x-3=3x+29 )what is the value of X?
Answer: x=16
Step-by-step explanation:
Move the variable to the left-hand side and change its sign
5 x - 3- 3 x =29
Move the constant to the right-hand side and change its sign
5 x - 3 x = 29 + 3
Collect like terms
2 x = 29+ 3
Add the numbers
2x= 32
Divide both sides by 2
and you get x=16
Step-by-step explanation:
5x - 3 = 3x + 29
5x - 3x = 29 + 3
2x = 32
x = 32/2 = 16
x = 16 ans
therefore, value of x is 16.

what does it mean to use quotient powers?
When we use the concept of power and a denominator in it, we will describe the root in another form.
What is the definition of potency?Potency is that which has power, strength, vigor and importance. In mathematics, power is the result of a number multiplied by itself one or more times. .
The base equation of the power is:
[tex]a^b = c[/tex]
Where:
a = base; b = exponent; c = power.So from the definition of power we have that when a division in the power occurs we will have to be the same thing as writing a root.

Express the area of the entire rectangle. Your answer should be a polynomial in standard form
First,
Length of Rectangle = (x + 9) units
Breadth of Rectangle = (x + 3) units
so,
Area = (x + 9) * (x + 3)
= x² + 9x + 3x + 27
= (x² + 12x + 27) units

14. The population of Booneville was 8745 in 2009, but dropped to 7913 in 2011. Find the
percent of decrease in population.
Answer:
The U.S. population 65 and older is now the largest in terms of size and percent of the population, compared with any previous census, according to a new 2010 Census brief [PDF] released today from the U.S. Census Bureau on the nation's older population. The group grew at a faster rate than the total population between 2000 and 2010.
According to the 2010 Census, there were 40.3 million people 65 and older on April 1, 2010, increasing by 5.3 million since the 2000 Census when this population numbered 35.0 million. The percentage of the population 65 and older also increased during the previous decade. In 2010, the older population represented 13.0 percent of the total population, an increase from 12.4 percent in 2000.
65 and Older Population Grew Faster than Total Population
Between 2000 and 2010, the population 65 and older grew 15.1 percent, while the total U.S. population grew 9.7 percent. The opposite happened between 1990 and 2000 when the growth of the older population was slower than the growth of the total population, with growth rates of 12.0 percent and 13.2 percent, respectively.
Population Size and Growth Varied Among the Older Age Groups
Examining the growth of 10-year age groups within the older population shows that 85- to 94-year-olds experienced the fastest growth between 2000 and 2010. This group grew by 29.9 percent, increasing from 3.9 million to 5.1 million.
Among five-year age groups in the older population, 65- to 69-year-olds grew the fastest. This age group grew by 30.4 percent, rising from 9.5 million to 12.4 million. The 65- to 69-year-old group is expected to grow more rapidly over the next decade as the first baby boomers start turning 65 in 2011.
The only older population age group to decline between 2000 and 2010 was the 75- to 79-year-old age group. This group decreased by 1.3 percent from 7.4 million to 7.3 million. The changes in this group mainly reflect the relatively low number of births during the early 1930s as fewer numbers of people entered these ages between 2000 and 2010.
