C. [tex] x = -2 [/tex]
Step-by-step explanation:
A rectangle has two lines of symmetry. That is, the line that divides the rectangle into two equal halves.
Taking a look at the rectangle that is placed on the coordinate grid. At what points do you think the two lines of symmetry can be located at that will give us two possible equal halves?
One will be horizontal, the other will be vertical.
For the horizontal line, the line of symmetry can be located at y = 5. If an horizontal line cuts through the rectangle at y = 5, we would have two equal halves.
Thus, an equation for a horizontal line is often represented as [tex] y = k [/tex]. Where k is a constant, because every coordinate point on the horizontal line would have the same value of k, which is where the line cuts across the y-axis. The slope of am horizontal line remains zero also.
Therefore, the equation of the line of symmetry of the rectangle shown in the coordinate grid would be:
✅[tex] y = 5 [/tex]
The second line of symmetry which is vertical, would cut across the rectangle at x = -2.
Thus, the slope of a vertical line is undefined.
The equation of a vertical line is represented as x = h.
Where h is a constant, since all coordinates along the vertical line would surely have a x-coordinate value of -2, regardless of what y-coordinate value they have.
Therefore, h, in this case is -2.
Thus, the equation that represents the second line of symmetry of the rectangle above would be:
✅[tex] x = -2 [/tex].
The two equations that represent the two lines of symmetry of the rectangle, respectively, are:
[tex] y = 5 [/tex]
[tex] x = -2 [/tex]
From the options given, the only correct option provided is:
[tex] x = -2 [/tex].

Answer:
Sale price of a sweat shirt is $15.30 and a soccer ball is $21.08.
Step-by-step explanation:
A). Usual price of a sweat shirt is = $18
Sale price of the sweat-shirt is 85% of the usual price.
Therefore, Sale price = 85% of $18
=
= $15.30
B). Usual price of a soccer ball is = $24.80
Sale price of the soccer ball is 85% of its usual price.
Therefore, Sale price = 85% of $24.80
=
= $21.08
Therefore, sale price of a sweat shirt is $15.30 and a soccer ball is $21.08.

Shannon is making identical balloon arrangements for a party. She has 32 maroon balloons, 24 white balloons, and 16 orange balloons. She wants each arrangement to have the same number of each color. What is the greatest number of arrangements that she can make if every balloon is used?
Answers
Answer:
8
Step-by-step explanation:
Given that:
Number of white balloon = 24
Number of maroon Ballon = 32
Number of orange Ballon = 16
To obtain the greatest number of arrangements ;
Find the greatest common factor of 24, 16 and 32
Factors of ;
24 = 1, 2, 4, 6, 8, 12, 24
16 = 1, 2, 4, 8, 16
32 = 1, 2, 4, 8, 16, 32
Hence, the greatest factor common to all three is : 8
Hence greatest number of arrangement that can be achieved is 8

At a concession stand, seven hot dogs and two hamburgers cost 14.50, two hot dogs and seven hamburgers cost 17.00. Find the cost of one hot dog and the cost of one hamburger
Answers
Given:
Seven hot dogs and two hamburgers cost 14.50
Two hot dogs and seven hamburgers cost 17.00.
To find:
The cost of one hot dog and the cost of one hamburger.
Solution:
Let the cost of one hot dog be x and the cost of one hamburger be y.
According to the question,
[tex]7x+2y=14.50[/tex] ...(i)
[tex]2x+7y=17.00[/tex] ...(ii)
Multiply (i) by 7.
[tex]49x+14y=101.5[/tex] ...(iii)
Multiply (ii) by 2.
[tex]4x+14y=34.00[/tex] ...(iv)
Subtract (iv) from (iii).
[tex]49x-4x=101.5-34[/tex]
[tex]45x=67.5[/tex]
Divide both sides by 45.
[tex]x=1.5[/tex]
Put x=1.5 in (i).
[tex]7(1.5)+2y=14.50[/tex]
[tex]10.50+2y=14.50[/tex]
[tex]2y=14.50-10.50[/tex]
[tex]2y=4[/tex]
Divide both sides by 2.
[tex]y=2[/tex]
Therefore, the cost of one hot dog is 1.5 and the cost of one hamburger is 2.

Given f(x) = 5(x + 1) + 16 , what is the value of x when f(x) = 1 ?
Answers
Answer:
x = -4
Step-by-step explanation:
1=5(x+1)+16
1=(5)(x)+(5)(1)+16 (Distribute)
1=5x+5+16
1=(5x)+(5+16)(Combine Like Terms)
1=5x+21
5x+21=1
5x+21−21=1−21
5x=−20
5x/5=−20/5
x=−4
Answer:
value of x is -4
Step-by-step explanation:
All you need to do is replace f(x) for 1.
1 = 5(x+1) + 16
backwards solve;
1 = 5x+5 +16
1=5x+21
1-21=5x
-20=5x
x=-4
That's all.
If it asks you if x=1, then just plug in 1 where ever x is. f(x) is symbolic of y.

What is a system of linear equations?A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
It is given that in a coordinate grid with 2 lines. The first line labelled f(x) passes through (-3, 3), (0,2), and (3, 1). The second line labelled g(x) passes through the points at (-3, 0) and (0, 2).
Plotting the two lines by using the points on the graph. After plotting the points there will be two lines that will intersect at the point ( 0, 2 ). Then the solution of the equation is ( 0,2).
Therefore, the solution to the system of linear equations is (0,2). The correct option is C.

If the trapezoid is isosceles, and KL = 2.8 units in length, what is the length of NM? Explain how you determined the length of NM.
Answers
Answer:
MN = 2.8 units
Step-by-step explanation:
By the property of isosceles trapezoid,
1). Bases are parallel.
2). Base angles of an isosceles trapezoid are congruent.
2). Opposite sides of the congruent angles are congruent.
By third property,
Measure of side KL = Measure of side MN
2.8 = Measure of side MN
Another way to find the length of MN is,
Distance between M and N = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
MN = [tex]\sqrt{(3-1)^2+(0+2)^2}[/tex] = [tex]\sqrt{8}[/tex]
MN = 2.8 units
Therefore, MN = 2.8 will be the answer.

Bob’s soup uses 18 drops of chili oil for every 4 cups of chicken broth. Yvonne wants her soup to have a weaker chili flavor than Bob’s soup. Which mixture should Yvonne use? A 18 drops of chili oil for every 2 cups of chicken broth
B 18 drops of chili oil for every 5 cups of chicken broth
C 20 drops of chili oil for every 4 cups of chicken broth
D 22 drops of chili oil for every 4 cups of chicken broth
Answers
Answer:
Yvonne should pick mixture B which has a lesser concentration of chili oil.
Step-by-step explanation:
Bob's soup concentration = 18 drops / 4 cups = 9 drops / 2 cups = 4.5 drops/cup
A. 18 / 2 = 9 drops/cup which is a greater concentration
B. 18 / 5 = 3.6 drops/cup which is a lesser concentration
C. 20/ 4 = 5 drops/cup which is a greater concentration
D. 22/ 4 = 5.5 drops/cup which is a greater concentration

You have $90 and your brother has $120. You are saving $18 per week

you and your brother to have the same amount of money saved? *

1 week

12 weeks
Answers
Answer:
10 weeks
Step-by-step explanation:
Let's set an equation for you and your brother.
You have $90 plus $18 for every week you save (x).
90+18x
And your brother has $120 plus $15 dollars per week that he saves (x)
120+15x
You want to have the sum of the money equal so combine the two concluded statements
90+18x=120+15x
Arrange them so that you have like terms on each side
90+18x-15x=12+15x-15x
90+3x=120
90-90+3x=120-90
3x=30
x=10
"x" is our number of weeks you and your brother save so the answer is 10 weeks
Just to be sure you can use our equation and plug 10 for every time you see x to make sure our answer is right.
