Y is inversely proportional to x, when Y = 7, x = 4.
True or False: the constant of proportionality, k, is 20.
Answer:
The given statement Y = 7, x = 4 is False.
Step-by-step explanation:
We are given:
Y is inversely proportional to x, when Y = 7, x = 4.
We need to tell if the statement is True or False: the constant of proportionality, k, is 20.
Y is inversely proportional to x
We can write it as: [tex]y\:\alpha \:\frac{1}{x}\\y=\frac{k}{x}[/tex]
Now, we need to check when Y=7, x = 4 is true or false
We are given k = 20
Now, I can find value of y, by putting values of k and x in the equation:
[tex]y=\frac{k}{x}\\y=\frac{20}{4}\\y=5[/tex]
When we put x = 4, and k =20, we get Y=5 and not Y=7
So, The given statement Y = 7, x = 4 is False.

Which of the following is true about a parallelogram?
The diagonals are equal.
All sides are congruent.
The diagonals bisect each other.
The diagonals are perpendicular.
Answer:
The diagonals bisect each other.
Step-by-step explanation:
Not all diagonals of a parallelogram are equal.
The only quadrilaterals with all four sides being congruent are rhombus and squares so parallelogram is wrong.
The diagonals of a parallelogram bisect each other.
The diagonals of a parallelogram are only perpendicular when it is a square.

In exponential growth functions, the base of the exponent must be greater than 1. How would the function change if the base of the exponent were 1? How would the function change if the base of the exponent were between 0 and 1?
Sample Response: If the base of the exponent were 1, the function would remain constant. The graph would be a horizontal line. If the base of the exponent were less than 1, but greater than 0, the function would be decreasing.
What did you include in your response? Check all that apply.
If the base were 1, the function would be constant.
If the base were 1, the graph would be a horizontal line.
If the base were between 0 and 1, the function would be decreasing.

A home-decorating company is determining the amount of fabric required for a customer's window treatments. A single window requires 11 2/3 yards and a double window requires 15 5/6
yards of fabric. If there are two single windows and one double window, how much fabric is required?
Answer:
[tex]2S + D = 34\frac{1}{6}\ yd[/tex]
Step-by-step explanation:
Represent single windows with S and double with D.
So, we have:
[tex]S = 11\frac{2}{3}\ yd[/tex]
[tex]D = 15\frac{5}{6}\ yd[/tex]
Required
Determine the amount of fabric for 2 singles and 1 double
The above statement implies:
[tex]2S + D[/tex]
Substitute values for S and D
[tex]2S + D = 2 * 11\frac{2}{3}\ yd + 15\frac{5}{6}\ yd[/tex]
Convert fractions
[tex]2S + D = 2 * \frac{35}{3}\ yd + \frac{65}{6}\ yd[/tex]
[tex]2S + D = \frac{70}{3}\ yd + \frac{65}{6}\ yd[/tex]
Tale LCM
[tex]2S + D = \frac{140+65}{6}\ yd[/tex]
[tex]2S + D = \frac{205}{6}\ yd[/tex]
[tex]2S + D = 34\frac{1}{6}\ yd[/tex]
Hence, [tex]34\frac{1}{6}\ yd[/tex] is needed
