So the first graph is Radical/Irrational Graph and the second is Parabola/Quadratic Graph.
You can find the domain by looking at the x-axis and for the range, look at the y-axis. That means all of x-axis is the domain and all of y-axis is the range.
From the first graph, the domain is from -2 to +infinite. But because there's a colored dot, it's either ≥ or ≤.
But because -2 is less than + infinite, we use ≤ instead. Thus, x ≥ -2
Remember that x-values can't be equal to infinite. So we use < instead since there's no x-values that are equal to ∞.
Or we can write in interval notation as [-2,+∞) for symbol "[ or ]" is equal to ≤ or ≥ and ") or (" is equal to > or <
Again, the domain for the first graph is x ≥ -2 or x ∈ [-2, +∞)
And the range, look at the y-axis. Because we can substitute x from -2 to less than ∞, that means the range is from -1 because when x = -2 then x = -1 to + infinite.
Therefore, the range is y ≥ -1 or y ∈ [-1, +∞)
Now for the second graph. Look at the x-axis to find the domain. We notice that the colored dot is at x = -3 and the one with white dot is at x =2. The one without the color or white dot is > or < while the colored one is ≥ or ≤.
So the domain is -3 ≤ x < 2 or x ∈ [-3, 2)
For range, look at the y-axis. Notice that the colored dot is at y = -5 and the maximum point is at y =4. The y =4 is still in the domain so the range still applies to the maximum point.
Therefore the range is -5 ≤ y ≤ 4 or y ∈ [-5, 4]

The Department of Streets of a city has a budget of $1,962,800 for resurfacing roads and hiring additional workers this year.
The cost of resurfacing a mile of 2-lane road is estimated at $84,000. The average starting salary of a worker in the department is $36,000
a year.
Write an equation that represents the relationship between the miles of 2-lane roads the department could resurface, m, and the number
of new workers it could hire, p, if it spends the entire budget.
Answers
Answer:
84,000 m + 36,000 p = 1,962,800
Step-by-step explanation:
Let m denotes number of miles of 2-lane roads the department could resurface and p denotes number of workers hired by the department of Streets of a city.
The cost of resurfacing a mile of 2-lane road is estimated at $84,000.
So,
Cost of resurfacing m miles of 2-lane road = $84,000 m
The average starting salary of a worker in the department is $36,000 a year
So,
Total salary paid to p workers = $36,000 p
Now, total amount is equal to $1,962,800.
84,000 m + 36,000 p = 1,962,800
An equation that represents the relationship between the miles of 2-lane roads the department could resurface, m, and the number of new workers it could hire, p, if it spends the entire budget is given as follows
[tex]84000\times m + 3600 \times p = 1,962,800.......(1)[/tex]
Equation (1) is the model equation for the given situation.
According to the question
Numbers of miles of 2 lane road = m
Number of workers that could be hired = p
The cost of resurfacing a mile of 2-lane road is estimated at $84,000. /mile
here m and p are our variables
The average starting salary of a worker in the department is $36,000 /year
The Department of Streets of a city has a budget of $1,962,80.
So the Equation for the budget can be written as
[tex]84000\times m + 3600 \times p = 1,962,800.......(1)[/tex]
Equation (1) represents One linear equation with two variables.

From the exponent's formula, the simplified form of the given question [tex]3^{2} \times 3^{4} \div 3^{2}[/tex] is 243.
What is the exponent's formula?Exponents formulas help solve exponents represented by [tex]\rm x^{n}[/tex] multiplying by itself n times. here, x is called the base and n is the exponent or power. [tex]\rm x^{n}[/tex] is read as x raised to the power of n.
The formula required
[tex]\rm a^{x} \times a^{y} = a^{x+y}[/tex]

Step-by-step explanation:
Since 7x-8= the angle above 11x-28, which lays on a 180 degree angle. You get the equation 7x-8+11x-28=180. You combine like terms on the left side and get 18x-36=180 add 36 to both sides and then divide both sides by 18 to get x=12.

Answers
Answer:
a. 16
Step-by-step explanation:
Triangles = 180 degrees
180 - 80 = 100
100 = (4x - 4) + (0.5x + 32)
4x - 4 + 0.5x + 32 =100
(4x + 0.5x) +(-4 + 32) = 100
4.5x + 28 = 100
4.5x + 28 -28 = 100 - 28
4.5x = 72
4.5x/4.5 = 72/4.5

Kyle plays softball. His goal is to have a batting average of .400 or greater by the end of the season. The ratio that relates the number of hits to the number of chances, called at-bats, is used to determine batting average in baseball and softball.Batting averagenumber of hits number of at bats So far this season, Kyle has 25 hits. He has been at bat 65 times. He expects to have 10 more at-bats this season
Answers
Answer:
The number of hits is [tex]T \ge 30 \ hits[/tex]
Step-by-step explanation:
From the question we are told that
The ratio of the number of hits to the number of chances is equivalent to the batting average
The number of chances is j = 65 + 10 = 75
The number of hit so far is n = 25
Generally the batting average can be represented mathematically as
[tex]A = \frac{n + k}{ j}[/tex]
Here k is the number of additional hits Kyle need to get in order to obtain the batting average of 0.40 or more
So
[tex]\frac{25 + k}{ 75} \ge 0.40[/tex]
=> [tex]k \ge 5 \ hits[/tex]
Hence the number of hits for Kyle to get a batting average of 0.400 or greater by the end of the season is
[tex]T \ge k + n[/tex]
=> [tex]T \ge 5 + 30[/tex]
=> [tex]T \ge 30 \ hits[/tex]

Suppose M is the midpoint of FG. Find the missing measure.
FM=12x−4, MG=5x+10
Answers
Answer:
[tex]\overline{FM}=20[/tex]
[tex]\overline{MG}=20[/tex]
Therefore,
[tex]\overline{FG}=40[/tex]
Step-by-step explanation:
Once M is the midpoint of FG, we conclude that
FM is half of FG and MG is half of FC and hence, FM = MG.
Given:
[tex]\overline{FM}=12x-4[/tex]
[tex]\overline{MG}=5x+10[/tex]
[tex]\overline{FM} = \overline{MG} \implies 12x-4 = 5x+10 \implies 7x=14 \implies \boxed{x = 2}[/tex]
So,
[tex]\overline{FM}=12x-4 = 12(2)-4=24-4=20[/tex]
[tex]\overline{MG}=5x+10 = 5(2)+10 = 10+10 =20[/tex]
a rectangles width is 13 more than its length if the perimeter is 82 feet what is the length and width ?
Answers
Answer:
Length = 27 feet and Width = 14 feet

W = Width (w+13)
P = 2L + 2W
82 = 2 (W+13) + 2W
82= 4W
56=4
W = 14 feet
Length = w + 13
13 + 14 = 27 feet
Length = 27 feet
