Answer:1 is exponential. 2 is linear. 3 is neither. 4 is linear. 5 is linear. 6 is exponential. 7a is exponential. I think 7b could be 10x + y = 10 but I'm not too sure. 7c is (8,4).
Step-by-step explanation:1. the coordinates are moving in an exponential way or something im not sure the correct wording but that is what exponential graphs look like. 2 is a straight line so it is linear. 3 is neither because the graph isn't exponential or linear. 4 is linear because the coordinates are subtracting at the same number. 5 is linear for the same reason at 4. 6 is exponential because the coordinates are multiplied by 2 each time. 7a is exponential because the coordinates are divided by 2 each time. 7b I'm not sure on. 7c is 8/4 because August is the 8th month and the month before (7) is 8 so 8 divided by 2 equals 4. So the 8th month would have to be 4. I hope that helps!
Carlita has a swimming pool in her backyard that is rectangular with a length of 26 feet and a width of 14 feet. She wants to install a concrete walkway of width c around the pool. Surrounding the walkway, she wants to have a wood deck that extends w feet on all sides. Find an expression for the perimeter of the wood deck.
Lets solve the question,
Given dimensions are:
Length = 26 feet
Width = 14 feet
concrete walkway with width = c
After installing the concrete walkway dimensions of the walkway will be,
Length = 26 + 2c
Width = 14 + 2c
She wants to build a wooden deck around the pool with a concrete walkway of width = w
Thus the dimensions of the wooden deck around the pool will be,
Length = [tex]26 + 2c + 2w[/tex]
Width = [tex]14 + 2c + 2w[/tex]
Now the perimeter of the wooden deck will be,
Perimeter = 2(length + width)
[tex]= 2[(26 +2c + 2w) + 2(14 + 2c + 2w)] = 2(40 + 4c + 4w) = (80 + 8c + 8w)[/tex]
Therefore, perimeter of the wooden deck would be: 80 + 8c + 8w
Perimeter = (80 + 8c + 8w)

Applying the the properties of Congruence.
Quadrilateral GHJK = Quadrilateral LMNP.
Find the given side length or angle measure.
PLEASE HELP NO Scams pleaseeeee !!
Answer:
[tex]LM = 35cm[/tex] and [tex]m \angle H = 98^o[/tex]
Step-by-step explanation:
For this problem, it is critical to understand what the opening statement means.
[tex]Quadrilateral GHJK \cong quadrilateral LMNP[/tex] means that each pair of corresponding sides between shapes are congruent (they have equal length), and each pair of corresponding angles between shapes are congruent (they have equal measure -- or same number of degrees when measured with a protractor).
So, it's important to be able to determine which pairs are the corresponding parts. When the congruence is given like [tex]Quadrilateral GHJK \cong quadrilateral LMNP[/tex] the letters are in a particular order. That order explains the order in which the shape is drawn out, and they put them in the same order for both shapes to mean that those are the letters that correspond with each other.
So, the first letter of each are a corresponding pair, the second letter of each are a corresponding pair, ... etc
In other words, point G and L correspond, point H and K correspond, etc.
Part 1 -- Find LMTo find the corresponding sides, the sides for these shapes are defined by a two adjacent letters (two letters next to each other in the name, or ... as it wraps around the end of the name... the first and last letter).
[tex]\overline{GH} \cong \overline{LM}\\ \overline{HJ} \cong \overline{MN} \\\overline{JK} \cong \overline{NP}\\\overline{KG} \cong \overline{PL}[/tex]
While all of that is true, we only have a few sides with any information in them. Notice that side GH in the first shape, and sides PL & LM in the second shape are the only sides with anything written. So, we just need to determine which sides correspond (and thus, are congruent), so that we know how to move forward. Looking at the list of congruent sides above, we see that [tex]\overline{GH} \cong \overline{LM}[/tex]
Since the sides (line segments) are congruent, their lengths are equal
[tex]GH = LM[/tex]
...so we can substitute the expressions for each angle into the equation and solve for the unknown value "x"
[tex]GH = LM\\(4x+3)=(6x-13)[/tex]
[tex](4x+3)+13=(6x-13)+13\\4x+16=6x[/tex]
[tex](4x+16)-4x=(6x)-4x\\16=2x[/tex]
divide both sides by 2
[tex]\frac{16}{2}=\frac{2x}{2}\\8=x[/tex]
So, to find the length, LM, we just need to look back at the expression for LM:
[tex]LM = 6x-13\\LM = 6(8)-13\\LM = 48-13\\LM = 35[/tex]
remembering that the lengths are measured in centimeters (as indicated on the diagram): [tex]LM = 35cm[/tex]
Part 2 -- Find m∠HTo find the corresponding angles, the angles for these shapes are defined by a single letter, so since the points correspond in order, the names of the shapes tell which angles are congruent.
[tex]\angle G \cong \angle L\\\angle H \cong \angle M\\\angle J \cong \angle N\\\angle K \cong \angle P[/tex]
While all of that is true, we only have a few angles with any information in them. Notice that ∠H in the first shape, and ∠L & ∠M in the second shape are the only angles with anything written. So, we just need to determine which angles correspond (and thus, are congruent), so that we know how to move forward. Looking at the list of congruent angles above, we see that
[tex]\angle H \cong \angle M[/tex]
Since the angles are congruent, their measures are equal
[tex]m\angle H = m\angle M[/tex]
...so we can substitute the expressions for each angle into the equation and solve for the unknown value "y"
[tex]m\angle H = m\angle M\\(9y+17)=(11y-1)[/tex]
subtract 1 from both sides
[tex](9y+17)+1=(11y-1)+1\\9y+18=11y[/tex]
subtract 9y from both sides
[tex]\\(9y+18)-9y=(11y)-9y\\18=2y[/tex]
divide both sides by 2
[tex]\frac{18}{2}=\frac{2y}{2}\\9=y[/tex]
So, to find angle H, we just need to look back at the expression for the measure of angle H:
[tex]m\angle H = 9y+17\\m\angle H = 9(9)+17\\m\angle H = 81+17\\m\angle H = 98[/tex]
remembering that the angle is measured in degrees (as indicated on the diagram): [tex]m \angle H = 98^o[/tex]

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference. The table that represents an arithmetic sequence is the third table.
What is arithmetic sequence?An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.
The explicit formula for any arithmetic series is given by the formula,
aₓ = a₁ + (x-1)d
where d is the difference and a₁ is the first term of the sequence.
For the table to be in an arithmetic sequence, the difference between any two consecutive terms must be equal.
For the first table, the difference between the first two terms is -6, while for the next two terms it is -12. Thus, it is not an arithmetic sequence.In the second table, the difference between the first two terms is 2 while the difference between the next two terms is 4. Thus, it is not an arithmetic sequence.In the third table, the difference between the first two terms is 1.4, the difference between the next two terms is 1.4.

The equation formed by the given condition is 960.5 + 35.75p ≤ 1818.50 and the number of players they can bring is a maximum of 24.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that,

Rent of bus = $960.50
Cost per player = $35.75/player
So,
Cost of bus + Cost per player × number of players ≤ The total amount that can be spent
960.50 + 35.75p ≤ 1818.50
35.75p ≤ 858
