This room has scratch marks on the floor. Tyler wants to slide the rug over to cover the scratch marks. What kind of translation should he perform that will conceal the scratches?
A.) Reflection
B.) Rotation
C.) Translation
D.) Dilation
Answer:
Option C
Step-by-step explanation:
To cover the scratch mark Tyler will move the rug so that it covers the mark.
Area of the rug = Length × Width
= (2 units) × (3 units)
= 6 square units
Area of the block in which the scratch mark is given
= 2 × 3
= 6 square units
Option A).
Reflection
If we reflect the rug across x or y axis image will be in other quadrants.
Therefore, Reflection is not the answer.
Option B).
Rotation
Rotation of the rug will move it to other quadrants or the size of the image will not cover the scratch mark.
Therefore, Rotation is not the answer.
Option C).
Translation
By shifting the rug to the required place we can cover the scratch mark.
Therefore, Translation will be the answer.
Option D).
Dilation
Dilation of the rug will differ the size.
Therefore, Dilation will not be the answer.
Option C will be the answer.

Tammy bought 6 CDs that were each the same price. Including sales tax, she paid a total of $94.80. Each CD had a tax of $0.05. What was the price of each CD before tax?
Answer:
$15.75
Step-by-step explanation:
first, figure out the value of the tax. that would be 0.30 because there are 6 cds, and each has a tax of 0.05. next, subtract the tax from the total. that would be 94.50. this gives us the price of the cds alone. lastly, divide the toal by 6. 94.50/6=15.75.
The speech and science clubs at a high school are both trying to get more involved in their community this year. Currently, they are planning fundraisers for a local nonprofit organization.
The speech club is selling calendars for $12 each. It originally had to pay $150 in printing fees, and the members plan to sell 10 calendars each day.
The science club is offering individual tutoring sessions for $15 per session. The club has no start-up costs, and plans to provide 6 sessions per day.
If x represents the number of days from the start of the fundraiser, what equations can the clubs use to find the total estimated amount each club will raise, y?
Answer:

Which of the statement(s) about the graph shown are true? Select all that apply.
a. An equation for the graph is y=2x^2-9x+7
b. the function has two roots
c. The solutions of the related quadratic equation are -1.5 and -3
d. The related quadratic equation has two solutions
Step-by-step explanation:
The solutions of the related quadratic equation are -1.5 and -3
To summarize, the true statements are:
(b) The function has two roots.
(d) The related quadratic equation has two solutions.
What is a Quadratic equation?ax²+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
To determine which statements about the quadratic function that passes through (1,0) and (3.5,0) are true, we need to use the fact that the roots (or x-intercepts) of a quadratic function can be found by solving the related quadratic equation, which is obtained by setting the function equal to zero.
Let's start with a statement (a). Plugging in the two points given into the equation y = 2x^2 - 9x + 7, we get:
At x = 1, y = 2(1)^2 - 9(1) + 7 = 0
At x = 3.5, y = 2(3.5)^2 - 9(3.5) + 7 = 0
This confirms that points (1,0) and (3.5,0) are indeed on the graph of the function, but it doesn't tell us whether this is the only function that passes through those points. So statement (a) alone is not sufficient to determine the true statements.
Next, let's consider statement (b). Since the graph passes through (1,0) and (3.5,0), we know that it must cross the x-axis at those two points. Therefore, the function has two roots or x-intercepts. Statement (b) is true.
Moving on to statement (c), we need to find the solutions of the related quadratic equation. Setting y = 2x² - 9x + 7 equal to zero, we get:
2x² - 9x + 7 = 0
Using the quadratic formula, we find that the solutions are:
x = (9 ± √(9² - 4(2)(7))) / (2(2)) ≈ 2.5 and ≈ 1.75
Therefore, statement (c) is false.
Finally, statement (d) asks whether the related quadratic equation has two solutions. We just found that it has two solutions, so statements (b) and (d) are true.
