Answer:
FALSE
Step-by-step explanation:
If y varies inversely as x., this is expressed as;
y = k/x
k is the proportionality constant
when y = 3 and x = 4
3 = k/4
k = 3 * 4
k = 12
when x = 15;
y = k/x
y =12/15
y = 4/5
Hence y is not equal to 12 when x = 15.
The correct answer is FALSE

Step-by-step explanation:
10 cubic feets volume is equivalent to 25.85 inches.
Answer:
Option B
Step-by-step explanation:
Volume of a cube is:
[tex]A = s^3[/tex]
s - side length
All sides are the same length in a cube.
We are given the information that the total volume of the cube is 10 cubic feet.
[tex]10=s^3\\\\\sqrt[3]{10}=\sqrt[3]{s^3}\\\\\boxed{2.154435... = s}[/tex]
2.154435... ≈ 2.15
The approximate height of the cube is 2.15 inches.
Since the height of the shelf is 24 inches tall, the cube should be able to fit.
2.15 < 24
Option B should be the correct answer.
Hope this helps.

Alright,Alex let say we have factored a quadratic into two binomial, for example
[tex](5x + 3)(6x - 4)[/tex]
If we set both of those equal to zero
[tex](5x + 3)(6x + 4) = 0[/tex]
We can used the zero product property in this case to find the roots of the quadratic equation.
This means that
[tex]if \: ab = 0 \: then \: a = 0 \: and \: b = 0[/tex]
This means we set each binomal equal to zero to find it root.
[tex]5x + 3 = 0[/tex]
[tex]5x = - 3[/tex]
[tex]x = - \frac{3}{5} [/tex]
[tex]6x + 4 = 0[/tex]
[tex]6x = - 4[/tex]
[tex]x = - \frac{2}{3} [/tex]
So our roots are negative 3/5 and negative 2/3 using zero product property
If n = 6, what is the value of 9n−4?
Answer:
50 because,
Step-by-step explanation:
9n means 9 times 6. Which equals to 54, subtract 4 to get 50
Answer:
50
Step-by-step explanation:
If n = 6 the equation becomes 9(6)-4 or 9 x 6 - 4
9 x 6 = 54
54 - 4 = 50
Thus, the answer is 50

By using graph of a function, the graph of the equation y + 6 = x + 4 has been shown below
What is graph of a function?A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.
here, we have,
At first, it is important to know about function.
There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.
Graph of a function f(x) is the collection of points of the form (x, f(x))
The equation is y + 6 = x + 4
y = x + 4 - 6
y = x - 2

Allison has a loyalty card good for a discount at her local hardware store. The item she wants to buy is priced at $36, before discount and tax. After the discount, and before tax, the price is $30.96. Find the percent discount.
Answer:
14%
Step-by-step explanation:
Original price of item = $36
Price after discount = $30.96
Percentage discount = x
To get the percent discount
x = 36 - 30.96/36
x = 5.06/36
x = 0.14
Percentage discount = 0.14 % 100
Percentage discount = 14%

Triangle XYZ is shown on the coordinate plane below:
If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?
Answer:
Step-by-step explanation:
Triangle XYZ has been reflected across a line y = 1,
Therefore, line y = 1 will work like a mirror and all the distance of the points of the points from this line will be equal after the reflection about this line.
Distance of X from this line = 2 units
After reflection distance of X' from the line of reflection will be 2 units in opposite side.
Therefore, coordinates of X' will be (3, 3)
