Answer:
C. c = 64
Step-by-step explanation:
The question is incomplete. Here is the complete question.
What value of c makes the equation true? Assume x greater-than 0 and y greater-than 0
RootIndex 3 StartRoot StartFraction x cubed Over c y Superscript 4 Baseline EndFraction EndRoot = StartFraction x Over 4 y (RootIndex 3 StartRoot y EndRoot) EndFraction
c = 12
c = 16
c = 64
c = 81
Given the function;
[tex]\sqrt[3]{\dfrac{x^3}{cy^4} } = \dfrac{x}{4y\sqrt[3]{y} }[/tex]
We are to find the value of c from the expression.
Step 1: Take the cube of both sides;
[tex](\sqrt[3]{\dfrac{x^3}{cy^4} } )^3= (\dfrac{x}{4y\sqrt[3]{y} })^3\\\dfrac{x^3}{cy^4} = \dfrac{x^3}{(4y)^3(\sqrt[3]{y} )^3}\\\dfrac{x^3}{cy^4} = \dfrac{x^3}{(64y^3)(y)}\\\\\dfrac{x^3}{cy^4} = \dfrac{x^3}{64y^4}\\[/tex]
Step 2: compare the denominator of both sides of the equation;
[tex]\dfrac{x^3}{cy^4} = \dfrac{x^3}{64y^4}\\\\On \ comparing;\\\\cy^4 = 64y^4\\[/tex]
Step 3: Divide both sides by y₄
[tex]\dfrac{cy^4}{y^4} = \dfrac{64y^4}{y^4}\\c = 64\\[/tex]
Hence the value of c is 64. Option C is correct

find the length of side BD round your answer to the nearest hundred
Answer:
The length of side BD is 4.62 units to the nearest hundredth
Step-by-step explanation:
In Δ ABC
∵ m∠ABC = 90°
∵ BD ⊥ AC
∴ AB × BC = BD × AC
∵ AB = 12 units
∵ BC = 5 units
∵ AC = 13 units
→ Substitute them in the equation above
∴ 12 × 5 = BD × 13
∴ 60 = 13 BD
→ Divide both sides by 13 to find BD
∴ 4.615384615 = BD
→ Round it to the nearest hundredth
∴ BD = 4.62 units
∴ The length of side BD is 4.62 units to the nearest hundredth

Answer:
It says to Graph y = 1/2x - 4
So equation y = 1/2x - 4
this corresponds to slope intercept form which is y = mx + b
M = slope = rise / run
B = y - intercept
First, start at the origin, (0,0)
Then go down 4, you should now be on the coordinate (0,4)
Now we need to use the slope.
The slope is 1 / 2, this means rise 1, run 2 (in this case 2 to the right because it is positive)
So, start at (0 , 4) and go up 1 unit then 2 to the right, then place a dot, keep repeating until you meet the end of the paper.
Then do the opposite so that you can graph the other side.
Down 1 and 2 to the left.
Answer:
Graph Points (0.-4) and (8,0) and connect the dots into a line
Step-by-step explanation:
To graph y=1/2x-4 you will need to find the y and x-intercept. To find an intercept you have to substitute the x and y variables with 0 one at a time. I first substitute the x variable with an 0 and got the equation y=-4 so my y-intercept is (0.-4). Then I substituted the y variable with 0 and got 0=1/2x-4, I added 4 on each side to get rid of it and got 4=1/2x. I then multiplied both sides by 2 to get the x by itself and got 8=x so my x-intercept is (8,0). Whenever your graphing slope-intercept form equations just find the y and x-intercepts, graph them, connect the dots.
Hope this helps you

The sum of the digits of a certain two digit number is 8. By reversing the digits the number is increased by 18. What is the number?
How can you find the slope from a table?
Answer:
you find slope from a table by taking any two points. the left side is the input of the table, the x, and the right side is the output the y. whenever you're finding the points to do slope, they must be correlated.
__x__|__y__
___2_|__4___
__3__|___6__
so if you want to choose 2 for the x input then you must choose the 4 as the y output.
After choosing the two points, (2,4) and (3,6), you need to find the slope which is y-y/x-x. so in this case it's 6-4/3-2. after subtracting you get, 2/1 which if you simplify, it's 2. Or you divide which is also 2. I hope this helped.

Apples cost $1.47 per pound. Danielle buys an apple that weighs 0.62 pound. To the nearest cent, how much does Danielle’s apple cost?
Answer:
91 cents
Step-by-step explanation: Just a hunch
The amount that Danielle’s apple cost is $0.91.
Using this formula
Cost=Sales price per pound× Weight per pound
Where:
Sales price per pound=$1.47
Weight in pound=0.62 pound
Let plug in the formula
Cost=$1.47×0.62
Cost=$0.91
Inconclusion the amount that Danielle’s apple cost is $0.91.

Triangle LMN with vertices L(0, 3), M(3, 4), and N(1, 2): a) 180° rotation about the origin b) dilation with scale factor of 2 using the origin as the center
Answer:
[tex]L" = (-6,0)[/tex] [tex]M" = (-8,-6)[/tex] [tex]N" = (-4,-2)[/tex]
Step-by-step explanation:
Given
[tex]L = (0,3)[/tex]
[tex]M = (3,4)[/tex]
[tex]N = (1,2)[/tex]
Required
Determine the new coordinates of L, M and N
Applying (a): 180 degrees rotation about the origin
When [tex](x,y)[/tex] is rotated about 180 degrees, the new point becomes [tex](-y,-x)[/tex]
So:
[tex]L = (0,3)[/tex] ==> [tex]L' = (-3,0)[/tex]
[tex]M = (3,4)[/tex] ==> [tex]M' = (-4,-3)[/tex]
[tex]N = (1,2)[/tex] ==> [tex]N' = (-2,-1)[/tex]
Applying (b): Dilation of scale factor, 2
The formula to apply here is;
[tex]New = Old * Scale\ Factor[/tex]
So:
[tex]L' = (-3,0)[/tex] becomes:
[tex]L" = L' * 2[/tex]
[tex]L" = (-3,0) * 2[/tex]
[tex]L" = (-6,0)[/tex]
[tex]M' = (-4,-3)[/tex] becomes:
[tex]M" = M' * 2[/tex]
[tex]M" = (-4,-3) * 2[/tex]
[tex]M" = (-8,-6)[/tex]
[tex]N' = (-2,-1)[/tex]
[tex]N" = N' * 2[/tex]
[tex]N" = (-2,-1) * 2[/tex]
[tex]N" = (-4,-2)[/tex]
Hence;
The new coordinates are:
[tex]L" = (-6,0)[/tex]
[tex]M" = (-8,-6)[/tex]
[tex]N" = (-4,-2)[/tex]

Bart wants to rent a car. The fee is $25 plus $0.55 per mile. He has budgeted $212 for the car. Write an
inequality to show how much he can spend for the car.
Answer:
25 + 0.55x ≤ 212
Step-by-step explanation:
Bart can only spend 212, hence the less than or equal to symbol. The cost of using the car must be at most 212, so 25 and 0.55x are on the same side. 0.55x represents the cost of driving an unknown amount of miles.
Write the equation of the line that is parallel to the line y= 3x+ 6 and passes through the point (4, 7).
Answer:
Is this slope?
Step-by-step explanation:
Answer:
y = 3x - 5
Step-by-step explanation:
Let the equation be y = mx + c
Since the equation is parallel to y = 3x + 6, gradients of the two eqns are the same
therefore, m = 3
sub (4, 7):
7 = 3(4) + c
c = -5
therefore, equation of the line is y = 3x - 5
