Which of the following equations shows the linear relationship between the x and y variables shown in the table of ordered pairs?
A. y = x - 5
B. y = x + 5
C. y = 5 - x
D. y = 5x
Answer:
x+5
Step-by-step explanation:
Hope this helps
Hi! I hope you're enjoying your day!
The linear relationship between x and y is
y=x+5
So we take a number x, add 5 to it, and that is equal to y.
Let's try and see if it works.
Let's take 2.
Add 5:
y=5+2
That should be equal to 7.
y=7
Yeah! It worked :)
Let's try another one.
Let's take 3.
y=3+5
y=8
Woo-hoo! It worked again :)
Hence, the answer is
[tex]\boxed{\boxed{\bold{Option~B~-y=x+5}}}[/tex]
Hope everything is clear.
If you have any questions, please comment.

The derivation for the equation of a parabola with a vertex at the origin is started below. = startroot (x minus 0) squared (y minus p) squared endroot = startroot (x minus x) squared (y minus (negative p)) squared endroot (x)2 (y – p)2 = (0)2 (y p)2 x2 y2 – 2py p2 = y2 2py p2 if the equation is further simplified, which equation for a parabola does it become? x2 = 4py x2 = 2y2 2p2 y2 = 4px y2 = 4py
The equation of parabola it becomes will be x²= 4py.The y-axis passes through (0, -a), and the directrix of the parabola x² = 4ay has the equation y + a = 0
What is a parabola?A parabola is a curve in which all points are at the same distance from two fixed points: the focus and a fixed straight line (the directrix ).
The given expression in the problem is;
[tex]x^2 +y^2-2py +p^2= y^2+2py+p^2[/tex]
On simplifying the gIven expression we get;
[tex]x^2- 2py = 2py \\\\ x^2= 2py+2py \\\\x^2=4py[/tex]
The y-axis passes through (0, -a), and the directrix of the parabola x²= 4ay has the equation y + a = 0. The y-axis passes through (0, a), and the center of the parabola x2 = -4ay has the equation y - a = 0.
Hence the equation of parabola it becomes will be x²= 4py

If you put 90ml of concentrate in a glass, how much water should be added?
Question wasn't clear, but I hope this helps!
→⭐Question:Lemon Squash If you put 90ml of concentrate in a glass, how
2 parts concentrate water should be added?
to 5 parts water x ml.
→⭐Answer:
Ratio: 2:5 or 2/5
Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:
2/5 = 90/x ( x = the unit (ml)/ how many ml of water)
Cross multiplication of the above equation will give us:
2x = 90 x 5 = 450
Dividing both sides by 2 we will get:
x = 450/2 = 225
Therefore, if we put 90ml of concentrate in a glass, the amont of water to be added is 225ml.
I hope this answer helps!

A cast iron pipe used as a water main for a home has an outer diameter of 8 in. If the pipe has a thickness of 0.6 in, what volume of iron does 29 in of pipe contain? Answer in cubic inches. Round your answer to the nearest hundredth if necessary. (Note: diagram is not drawn to scale.)
The volume of cast iron pipe is 1053.19 in³.
Volume of CylinderThe volume of a cylinder can be calculated by: [tex]\pi *r^2*h[/tex], where:
r = radius
h= height
In this question, the cylinder is represented for a pipe, where:
r = inner diameter= [tex]inner\;diameter=outer\;diameter-2*thickness[/tex]
h= length of pipe
From this, you should apply the volume of the pipe. See the steps:
Step 1 - Find the inner diameterinner diameter=outer diameter-2*thickness
inner diameter=8-2*0.6
inner diameter=8-1.2=6.8 in
Step 2 - Find the volume of the pipe[tex]V_{pipe}=\pi *r_{internal}^2*h\\ \\ V_{pipe}=\pi *(\frac{6.8}{2} )^2*29\\ \\ V_{pipe}=\pi *(3.4)^2*29=1053.19\;in^3[/tex]

A clothing store is having a sale: buy one shirt at
regular price, and get a second shirt of equal or lesser
value for 35% off. Jason buys two shirts at the sale.
The regular price of the first shirt is $32.00, and the
regular price of the second shirt is $20.00. Including
sales tax, Jason pays $48.60 for the two shirts.
Using proportions, it is found that the sales tax is of 8%.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, he buys a shirt for $32.00, then the second at 35% off, hence the price of the second shirt is:
P = (1 - 0.35) x 200 = 0.65 x 20 = $13.
The total price of the shirts is:
T = $32.00 + $13.00 = $45.00.
Hence, he pays $3.60 in taxes, and the sales tax is given by:
Tax = (3.6/45) x 100% = 8%.

The percentage of actual yield is 60.66%.
What is the percentage?The percentage of a number is the hundredth part of that number.
Given that the total yield is 872.7 grams and the actual yield is 529.4 grams.
The percentage is calculated by the formula given below.
[tex]Percentage\; of\; Yield = \dfrac {Actual \;Yield }{ Total\; Yield}\times 100[/tex]
Substituting the values, we get the percentage,
[tex]Yield \;\% = \dfrac {529.4}{872.7}\times 100[/tex]
[tex]Yeils\;\%=60.66\;\%[/tex]
Hence we can conclude that the percentage of actual yield is 60.66%.
