Answer:
C: -14x - 7
Step-by-step explanation:
-14x - 7 is equivalent to (-8x+2) - (6x+9)
The expression evaluates to -14x - 7.
The correct option is 3.
What is Algebra?The area of mathematics known as algebra aids in the representation of circumstances or problems as mathematical expressions. To create a meaningful mathematical expression, it takes variables like x, y, and z together with mathematical operations like addition, subtraction, multiplication, and division.
As per the given data:
Expression:
(-8x + 2) - (6x + 9)
Simplifying to evaluate the expression:
(-8x + 2) - (6x + 9)
= -8x + 2 - 6x - 9
= -8x - 6x + 2 - 9
= -14x -7
Hence, the expression evaluates to -14x - 7
The correct option is 3

What are the steps to finding areas?
Trapezoid:
Rectangle:
Circle:
Triangle:
Answer:
Trapezoid: So basically to find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.
Rectangle: To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.
Circle: The area of a circle is pi times the radius squared (A = π r²).
Triangle: To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles.
A 12-pound bag weighs more than a 200-ounce bag. True or false?
Question 9 options:
True
False
Answer:
False. A 200-ounce bag would weigh more than a 12-pound bag.
Hope this helps!
The statement "A 12-pound bag weighs more than a 200-ounce bag." is True.
What is Unit Conversion?The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.
Given:
A 12-pound bag weighs more than a 200-ounce bag.
As, we know
1 pound = 16 ounce
So, the weight of bag in ounces
=12 pound
= 12 x 16
= 192 ounce
So, the statement is True.

The graph shows the prices of different numbers of bushels of corn at a store in the current year. The table shows the prices of different numbers of bushels of corn at the same store in the previous year.
A graph shows the Number of Bushels on the x-axis and the Price of Corn in dollars on the y-axis. The x-axis scale is shown from 0 to 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.

Part A: Describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value.
Part B: How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show your work.
Answer:Part A:8 Part B:$1
Step-by-step explanation:
Part A: 7 dollars
- The graph shows that 2 bushels is 14 dollars, because the graph has a straight line, the rate remains constant you must divide the sides by two to find the amount for one bushel which would be 7 dollars.
- And to double check you would divide 28 by 4, 42 by 6, 56 by 8, 70 by 10, 84 by 11, and 98 by 12. they all equals 7 dollars So, the equation would be y = 7x.
- 7 can be known as the slope and rate of change.
Part B:2 dollars
- The years before show 2 bushes was 10 dollars
-so you would divide 10 by two you would get five To double check you would do the same thing with 20 by 4, 30 by 6 and 40 by 8, and they all equal 5 dollars.
-if you use this answer be sure to reword it so you dont get copy write and integrity. have a great day or night.

A candy bar costs $0.79
Find the price of the candy bar if it is sold with a 65% mark up
A. $1.58
B. $1.44
C. $1.30
D. $1.17
Answer:
C. $1.30
Step-by-step explanation:
Multiply 0.79 and 0.65 (65%) which is about 0.51.
Add that to 0.79.
Answer:
$ 1.30
Step-by-step explanation:
Increased price = 65% of $0.79
[tex]\frac{65}{100}*0.79[/tex]
= 0.65 * 0.79
= 0.5135
= $ 0.51
Selling price = 0.79 + 0.51 = $ 1. 30

Look at the rectangle and the square:
A rectangle PQRS and square LMNO are drawn side by side. The length SR of the rectangle is labeled as 12 inches, and the width QR is labeled as 6 inches. The side LM of the square is labeled as 6 inches
Sam says that the length of diagonal SQ is two times the length of diagonal OM.
Is Sam correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals.
Answer:
False
Step-by-step explanation:
Let's consider the triangle SQR. We know it is right-angle because part of the rectangle PQRS. We can use the Pythagorean theorem:
[tex]SQ^{2} = RQ^{2} + SR^{2} \\SQ^{2} = 36 + 144 = 180\\SQ = \sqrt{180} = 13,4[/tex]
We can do the same for the square in which ON = 6 because it's a square:
[tex]OM^{2} = MN^{2} + ON^{2} \\OM^{2} = 36 + 36 = 72\\OM = \sqrt{72} = 8.5[/tex]
Now let's compare them:
8.5 X 2 = 17 so OM X 2 is not equal to SQ
The sentence is false.
