What is the equation for the following graph?
a. y=-4
b. y=4
c. x=4
d. x=-4
Answer:
x=4
Step-by-step explanation:
Consider the coordinate pair (4,y)
We observe that,
y can take any real values to lie on the graph of the equation.
As y really isn't a constant, we exclude it and take the equation as x=4

Step-by-step explanation:
The elves at Santa’s Workshop are trying to wrap the biggest box they can with the last bit of wrapping paper they have. All of the boxes they have are rectangular prisms with a base whose length is three times the width. Assume that they can make the box have any height they wish. There is 240 square inches of wrapping paper left.
What dimensions will maximize the volume of the box given the amount of wrapping paper the elves have? Make sure to show all your work and write a sentence at the end to interpret your results.
Answer:
The length of the box is 2×√30 inches long, the width of the box is 2×√(10/3) inches long, while the height of the box is √30 inches long
Step-by-step explanation:
The given parameters are;
The length of the last rectangular prism box = 3 × The width of the box
The area of the available wrapping paper = 240 in.²
Let L represent the length of the rectangular prism box, let W represent the width of the rectangular prism box and let h, represent the height of the rectangular box
Therefore, we have;
L = 3 × W
The surface area of the box, A = 2 × L × W + 2 × L × h + 2 × W × h
Whereby, L = 3 × W, we have;
A = 2 × 3 × W × W + 2 × 3 × W × h + 2 × W × h = 8·h·W + 6·W²
A = 8·h·W + 6·W² = 240
8·h·W + 6·W² = 240
8·h·W = 240 - 6·W²
h = (240 - 6·W²)/(8·W)
The volume, V = L × W × h
∴ V = 3 × W × W × h = 3 × W² × h
V = 3 × W² × h
∴ V = 3 × W² × (240 - 6·W²)/(8·W) = 3/8 × W × (240 - 6·W²) = 90·W - 9/4·W³
dV/dW = d(90·W - 9/4·W³)/dW = 90 - 27/4·W²
At the maximum point, dV/dW = 0, which gives;
dV/dW = 90 - 27/4·W² = 0 at maximum point
27/4·W² = 90
W² = 4/27 × 90 = 40/3
W = ±√(40/3) = ±2×√(10/3)
Differentiating again and substituting gives;
d²V/dW² = d(90 - 27/4·W²)/dW = - 27/4·W
Given that when W = 2×√(10/3), d²V/dW² is negative, and when W = -2×√(10/3), d²V/dW² is positive, W = 2×√(10/3) is the local maximum point
Therefor, the dimensions of the box are;
W = 2×√(10/3)
L = 3 × W = 3 × 2×√(10/3)
L = 3 × 2×√(10/3) = 2×√30
L = 2×√30
L = 6 ×√(10/3)
h = (240 - 6·(2×√(10/3))²)/(8·(2×√(10/3))) = √30
h = √30
Therefore, the length of the box is 2×√30 inches long, the width of the box is 2×√(10/3) inches long, while the height of the box is √30 inches long.

does the ordered pair (8,48) satisfy the direct equation y=6x? explain why or why not
Answer:
i think yes the order pair of (8,48) satisfy the direct equation y=6x
Step-by-step explanation:
Find the slope of the line passing through the points (-8,-8) and (6,-8)
Answer:
Slope = 0
So, the line is parallel to x-axis
Step-by-step explanation:
(x₁ , y₁) = (-8, -8) & (x₂ ,y₂) = (6 , -8)
[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\=\frac{-8-[-8]}{6-[-8]}\\\\=\frac{-8+8}{6+8}\\\\= 0[/tex]

What is an equation of the line that passes through the points (4,−1) and (8, 5)? Put your answer in fully reduced form.
HELP PLS
Answer:
y=2/3x-7
Step-by-step explanation:
The slope intercept formula is
y=mx+b
(m) is the slope (rate of change)
(b) is the y intercept (where the line crosses the y axis [vertical])
We need to find the slope and the y intercept. First we will find the slope.
The formula for slope is y1-y2/x1-x2
In and ordered pair the first value is the (x) and the second is the (y).
(x, y)
We take the (y) of one of the given points and subtract the (y) of the second given point, then divide it by the (x) of one of the given points and the (x) of the other given point.
5-(-1)/8-4
Simplify.
5-(-1) =5+1= 6
8-4=4
6/4 Simplify
3/2 is our slope.
Now we apply out new slope into our y=mx+b
y=3/2x+b
Now we need to find the (b) which is the y intercept.
To do this we need to use one of our given points, you can choose either but for this I'll use (4, -1).
In this ordered pair 4 is the (x) and -1 is the (y)
So replace (y) with -1 and (x) with 4
-1=3/2(4)+b
Now solve as usual.
-1=6+b
subtract 6 from each side
-7=b
b=-7
Put our (m) and (b) into our formula.
y=2/3x-7 is our equation.

PLEASE HELP ILL MAKE BRAINLIEST!!!!!
Answer:
The first one because every x value can only have one y value
Step-by-step explanation:
The set of ordered pairs that represents y as a function of x are; {(0, 0), (1, 1), (2, 3), (3, 3)}
We must be aware that, dependent variable, y can only be a function of x if;
For every value of x, there must only be one value of y.
In essence,
For case 1:
y is a function of x, because for every value of x, there's only one value of y.For Case 2:
y is not a function of x, because there's two values of y for a value of x.For Case 3:
y is not a function of x, because there's two values of y for a value of x.For Case 4:
y is not a function of x, because there's two values of y for a value of x.Read more:
