Answers
Answer:
B
Step-by-step explanation:
Well you first know that your y-intercept is -2 (look on the graph) so you can automatically cancel out option A and D. Now this leaves us with B and C. The only thing that is different between the two answers is the slope. Slope = Δy/Δx (change in y divided by change in x) So from (0,-2) to the next point (4, -1) How far is the x and y? Well you go up one and to the right 4. the change in y is up one (+1) and the change in x is right 4 (+4).
You can also do this
\frac{-2-(-1)}{0-4} = \frac{-1}{-4} = 1/4\\
(y2-y1)/(x2-x1) (the numbers are subscripts)

If the value of a in the quadratic function f(x) = ax2 + bx + c is 4, the function will_______.
A) open down and have a maximum
B) open up and have a maximum
C) open down and have a minimum
D) open up and have a minimum
Answers
Answer:C
Step-by-step explanation:
The function will be open up and have a minimum point.
Option D is correct.
Quadratic function:If a quadratic function is given as;
[tex]f(x)=ax^{2} +bx+c[/tex]
When [tex]a > 0[/tex] , then the graph of function will be open up and have a minimum point.When [tex]a < 0[/tex] , then the graph of function will be open down and have a maximum point.Since, It is given that value of a is 4 ,
So that, [tex]a > 0[/tex] . Hence, the function will be open up and have a minimum point.

Which expression is equivalent to (−8x+2)−(6x+9)?
Answers
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

Kyle measured the length, width, and height of a donut box after all the donuts had been eaten. His measurements are shown below.
What is the volume of the donut box?
Answers
Answer:
1/6 ft³
Step-by-step explanation:
The volume of a box can be found using the following equation:
Volume of box = width x length x height.
It is given to us that:
length = 1 ft.
width = 2/3 ft.
height = 1/4 ft.
Multiply the 3 measurements together:
V (volume) = 1 x 2/3 x 1/4
V = (1 * 2 * 1)/(3 * 4) = 2/12 ft³ , or if simplified 1/6 ft³
1/6 ft³ is your answer.
~
= (1)(2/3)(1/4)
=2/12

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.
Previous Year
Number of Bushels
Price of Corn (dollars)

8
40
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.
Answers
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.
