Determine any data values that are missing from the table, assuming that the data represent a linear function.
a. Missing x:13 Missing y:20
b. Missing x:13 Missing y:19
c. Missing x:11 Missing y:20
d. Missing x:11 Missing y:19
Answer:
d. Missing x:11 Missing y:19Step-by-step explanation:
It can be determined that the function is:
y = 0.5x + 12.5So missing x is:
18 = 0.5x + 12.5 ⇒ 0.5x = 5.5 ⇒ x = 11Missing y is:
y = 13*0.5 + 12.5 = 19Missing numbers are:
x= 11 and y = 19Correct choice is d.
FIRST METHOD
Answer:
Missing x = 11Missing y = 19Step-by-step explanation:
Given the table
x y
7 16
9 17
Missing x 18
13 Missing y
From the table, it is clear that y-values are incremented by 1 unit and the x-values are incremented by 2 units.
i.e.
y = 17-16 = 1
y = 18-17 = 1
as 19-18 = 1
Thus,
Thus, the value of Missing y = 19
also the x-values increment by 2.
i.e.
x = 9-7 = 2
as x = 11 - 9 = 2
Thus, Missing x = 11
Therefore,
Missing x = 11Missing y = 192ND METHOD
Given that the table represents a linear function, so the function is a straight line.
Taking two points
(7, 16)(9, 17)Finding the slope between (7, 16) and (9, 17)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(7,\:16\right),\:\left(x_2,\:y_2\right)=\left(9,\:17\right)[/tex]
[tex]m=\frac{17-16}{9-7}[/tex]
[tex]m=\frac{1}{2}[/tex]
Using the point-slope form to determine the linear equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 1/2 and the point (7, 16)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-16=\frac{1}{2}\left(x-7\right)[/tex]
Add 16 to both sides
[tex]y-16+16=\frac{1}{2}\left(x-7\right)+16[/tex]
[tex]y=\frac{1}{2}x+\frac{25}{2}[/tex]
Thus, the equation of the linear equation is:
[tex]y=\frac{1}{2}x+\frac{25}{2}[/tex]
Now substituting y = 18 in the equation
[tex]18=\frac{1}{2}x+\frac{25}{2}[/tex]
Switch sides
[tex]\frac{1}{2}x+\frac{25}{2}=18[/tex]
subtract 25/2 from both sides
[tex]\frac{1}{2}x+\frac{25}{2}-\frac{25}{2}=18-\frac{25}{2}[/tex]
[tex]\frac{1}{2}x=\frac{11}{2}[/tex]
[tex]x=11[/tex]
Thus, the value of missing x = 11 when y = 18
Now substituting x = 13 in the equation
[tex]y=\frac{1}{2}\left(13\right)+\frac{25}{2}[/tex]
[tex]y=\frac{13}{2}+\frac{25}{2}[/tex]
[tex]y=\frac{13+25}{2}[/tex]
[tex]y=\frac{38}{2}[/tex]
[tex]y = 19[/tex]
Thus, the value of missing y = 19 when x = 13
Hence, we conclude that:
The value of missing x = 11The value of missing y = 19Hence, option D is true.

Step-by-step explanation:
Are the lines x− 2y= 4 and y= 2x − 2 parallel, perpendicular, or neither? Explain your answer. [ Select ] ; their [ Select ] [ Select ] the same and [ Select ] receiprocals.
Answer:
Neither.
Step-by-step explanation:
First we alter the first equation to match the second.
x - 2y = 4
2y = x - 4
y = x/2 - 2.
Next we compare the slopes
2x = 2
x/2 = 1/2
Their slopes are reciprocals, but they aren't opposites. Therefore they are neither parallel nor perpendicular.

d. One holding pen uses 500 feet of fence
wire and 100 feet of tie wire. A farmer
uses a combined length of 1,000 yards of
wire. What length of tie wire was used?
Help me
9514 1404 393
Answer:
500 ft or 166 2/3 yards
Step-by-step explanation:
The tie wire is (100)/(100 +500) = 1/6 of the total length of wire used. If 1000 yards of wire is used, 1/6 of that amount can be expected to be tie wire. That is ...
(1000 yd)/6 = 166 2/3 yd = 500 ft

Step-by-step explanation:
Triangle ABC contains side lengths b=3 inches and c= 5 inches in two or more sentences describe whether or not it is possible for mangle B =45 degrees
Answer:
Since sine of all angles are always less than one, this shows there is no possible way to have an angle C. Thus it is impossible to have a triangle ABC with the given properties of side lengths b=3 inches and c= 5 inches to have angle B =45 degrees.
Step-by-step explanation:
In the attached drawing, each of the tic-marks are equal and
represent 1 inch each. The angle B has measure 45. We can
see by the arc that the line AC, which equals 3 inches, is
not long enough to reach the slanted side of the 45 angle.
Therefore triangle ABC is not possible. We can also show
by the law of sines that no triangle ABC with the given
properties in possible.

Sara bought a pen at 25$ and sold it for $30. She then bought the same pen back at $35 and sold it again for $40. Did she make or lose money from these two deals in the end.
Answer:
honestly if u ask me ima have to say she lost some money cause
Step-by-step explanation:
she got it for 25 right then she got an exstra 5 dollars cause she sold it
for 30 then she got the same pen for 35 when she got it for 25 the first time so 25-35 = 10 meaning she lost 10 dollars and got 10 dollars back because if u add the 5 dollars from the 30 then from the 40 u get ten meaning
she just got her money right back
Which of these figures has rotational symmetry?
Rotational symmetry, also known as radial symmetry, is the quality that a form exhibits when it looks the same after a partial turn rotation. The correct option is D.
What is Rotational Symmetry?
Rotational symmetry, also known as radial symmetry, is the quality that a form exhibits when it looks the same after a partial turn rotation. The degree of rotational symmetry of an item is the number of possible orientations in which it appears precisely the same for each revolution.
Since for the rotational symmetry, the figure should look the same even if the figure is rotated. Thus, the figure that has a rotational symmetry is a rhombus. Hence, the correct option is D.

On holidays three friends decided to buy a Christmas tree for $96. They made a cash contribution of 3: 5: 8. The two friends who invested less decided to return the third friend's money so that their cash contributions became the same. What is the ratio of the money returned by the first person to the money returned by the second person
Answer: 7:1
Step-by-step explanation:
First off, we see that the contribution was divided into 16 parts (8+5+3). If the tree was $96, 96/16 = $6, so each individual part was $6.
First Person: 3(6) = $18
Second Person: 5(6) = $30
Third Person: 8(6) = $48
We know that after the two friends return the money, the $96 will have been split evenly between all three of them.
96/3 = 32 - each person pays $32 total
Because each person has to pay $32 total, the first person must return $14 and the second person must return $2. This means that the ratio is 14:2 which can be reduced to 7:1.
Person 1: 32-18 = 14
Person 2: 32-30 = 2
Person 3: 48-14-2 = 32. - check to see if we were correct, which we are because after two friends pay 3rd back, their total is also 32 dollars.
Mr. Richards garden is shaped like a rectangle. The length of garden is 10 meters more than twice the width. What expression represents the length in meters of a fence needed to fully surround garden
Answer:
The expression for length of fence in meters is: 6w+20 meters
Step-by-step explanation:
Let l be the length and w be the width of the given garden
Then according to given statements
[tex]l = 2w+10[/tex] Eqn 1
As we have to find the length of fence to fully surround garden that means the perimeter has to be found.
The formula for perimeter is given by:

Today's cafeteria specials at a high school in Ashland are a deluxe turkey sandwich and a chef salad. During early lunch, the cafeteria sold 14 turkey sandwiches and 61 chef salads, for a total of $150. During the late lunch, 14 turkey sandwiches and 25 chef salads were sold, for a total of $78. How much does each item cost? A turkey sandwich costs $ , and a chef salad costs $ .
Answer:
Equation 1: 14t + 61s = 150
Equation 2: 14t + 25s = 78
Use Elimination (x)
(-1) (14t + 25s) = (78) (-1)
-14t - 25s = -78
14t + 61s = 150
+ -14t - 25s = -78
--------------------------
36s = 72
s = 2
Salad costs $2
Then find t
14t + 61(2) = 150
14t + 122 = 150
14t = 28

Answer:
Width = 66 inches
Step-by-step explanation:
Zelda has 300 inch roll of binding for a quilt.
The length must be 84 inches
We need to find its width. Let it is b.
Let us assume that the quilt is in the shape of rectangle. The perimeter of the rectangle is given by :
P = 2(l+b)
300 = 2(84+b)
150 = 84+b
b = 150-84
b = 66 inches
So, the required width is 66 inches.
