Answer:
y = -2x + 3
Step-by-step explanation:
5 x -2 + 3 = -7
3 x -2 + 3 = -7
9 x -2 + 3 = 1
-3 x -2 + 3 = 9
You just have to test all of the options, everything, out and pick what fits.
Hope that helps!
Explanation:
You will have to try to substitute the numbers shown in the table with the 4 equations. And see which equation satisfies all the expressions in the table.
y = -2x + 3
Sub x = 5 and y = -7,
-7 = -2(5) + 3
-7 = -10 + 3
-7 = -7
(x=5 and y=-6 satisfies the equation y=-2x+3)
Sub x=3 and y=-3,
-3 = -2(3) + 3
-3 = -6 + 3
-3 = -3
(x=3 and y=-3 also satisfies the equation y=-2x+3)
Same goes for all the other numbers...
Hope it helps :)

Katherine has a fish tank shaped like a triangular prism in her living room. The triangle that forms the base of the tank has a base of 24 inches and a height of 20 inches. The entire tank is 36 inches tall. What volume of water is needed to fill the tank if the tank is only filled to 6 inches below the top?
Answers
Answer:
[tex]Volume = 7200in^3[/tex]
Step-by-step explanation:
Given
[tex]B = 24[/tex] --- base of the tank base
[tex]h = 20[/tex] --- height of the tank base
[tex]H = 36[/tex] --- height of the tank
Required:
Determine the volume of water needed for 6 inches below the top
First, calculate the area of the tank base.
[tex]Area = \frac{1}{2}Bh[/tex]
[tex]Area = \frac{1}{2}*24*20[/tex]
[tex]Area = 12*20[/tex]
[tex]Area = 240[/tex]
If the tank is filled 6 inches below the top, this means that the height of the water is H - 6.
So, the volume is:
[tex]Volume = Area * (H - 6)[/tex]
Substitute 240 for Area and 36 for H
[tex]Volume = 240 * (36 - 6)[/tex]
[tex]Volume = 240 * 30[/tex]
[tex]Volume = 7200in^3[/tex]

Consider left and right sides of the equations as linear functions.
Then:
1. The equation 1 has lines with the same slope (2) but different y-intercepts (7 and -7), therefore the lines are parallel and no solution.2. The lines have different slopes (3 and 2), therefore they intersect and there is one solution.3. After opening the parenthesis we get both sides same, meaning the lines are same and overlap. The equation has infinitely many solutions.When I...

What are the restrictions for y for the following equation? X=10/5+y
Answers
Answer:
y = -5
Step-by-step explanation:
The restriction for the value of y is the value of the variable that will make the function undefined
The function is undefined when the denominator is zero i.e when 5 + y is zero
5+y = 0
y = 0-5
y = -5
Hence the restrictions is at when y = -5

1 = $312.50
R = 25%
T = 0.25 years
Find P.
Please help :)) for 35 points !
Answers
Answer:
Step-by-step explanation:
I = PRT
PRT = I
P = I/RT
P = 312.50/(.25)(.25)
P = 312.5/.0625
P= $5000
Principal for the given interest, rate of interest and time period is $5000.
Given that, I = $312.50, R = 25% and T = 0.25 years.
What is the simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.
Now, SI=(P × R × T)/100
312.50= (P × 25 × 0.25)/100
⇒ P × 25 × 0.25 = 31250
⇒ P = 31250/6.25
⇒ P = $5000
Therefore, principal for the given interest, rate of interest and time period is $5000.

A woman is standing 12 feet from a sculpture. The angle of elevation from her eyes to the top of the sculpture is 35º. If the woman's eyes are 5 feet 6 inches off the ground, how tall is the sculpture? Round answer to the nearest thousandth of a foot.
Answers
Answer:
13.903 feet
Step-by-step explanation:
Let the height from the woman's eyes to the top of the sculpture be represented by x.
So that,
Tan 35 = [tex]\frac{x}{12}[/tex]
x = Tan 35 x 12
= 0.70021 x 12
= 8.4025
x = 8.403 feet
The height of the sculpture = The woman's eye level to the ground + x
= 5 feet 6 inches + 8.403 feet
= 5.50 feet + 8.403 feet
= 13.903 feet
Thus, the sculpture has a height of 13.903 feet.
