An expression is shown below:
f(x) = 2x² − x − 10
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
(10 points)
Answers
Part A
[tex]2x^2 -x-10=0\\\\(x+2)(2x-5)=0\\\\x=-2, \frac{5}{2}[/tex]
So, the x-intercepts are (-2,0) and (5/2, 0).
Part B
The vertex will be a minimum because the leading coefficient of the quadratic is positive, meaning the graph will open up.
The vertex has an x-coordinate that is the average of the roots, which in this case is 1/4.
[tex]f(1/4)=-81/8[/tex]
So, the coordinates of the vertex are [tex]\left(\frac{1}{4}, -\frac{81}{8} \right)[/tex]
Part C
Plot the two x-intercepts and the vertex. Then, draw a parabola through these points that opens up.

A standard solid with six square faces, in Euclidean Geometry; that is a normal hexahedron. Themes connected: Polyhedron. Since a cube's volume is represented, the cube of that quantity is called in arithmetic and algebra, in terms of edge e, and [tex]e^3[/tex], and the further calculation can be defined as follows:
When there is 1 cube then the number of surfaces[tex]\bold{=6}[/tex]When there is 2 cube then the number of surfaces [tex]\bold{=6 \times 2-2}[/tex]When there is 3 cube then the number of surfaces [tex]\bold{=6 \times 3-2\times 2}[/tex]So, when n cubes are there
[tex]\to \bold{=6\times n-2(n-1)}[/tex]
[tex]\bold{=6n-2n+2}\\\\\bold{= 4n+2}[/tex]
when n=15 then:
[tex]\to \bold{=6\times 15-2(15-1)}[/tex]
[tex]\bold{=90-30 +2}\\\\\bold{=60+2}\\\\ \bold{=62}[/tex]
So, the final answer is "62 and 4n+2".

2(1/2 w -4) ≤-(w-5)
HELP FAST
Answers
2(1/2 w -4) ≤-(w-5)
Use the distributive property:
w-8 ≤ -w + 5
Add 8 to both sides:
w ≤ -w + 13
Add w to both sides:
2w ≤ 13
Divide both sides by 2:
w ≤ 13/2
Answer:
w ≤ 13/2
Step-by-step explanation:
2(1/2w - 4) ≤ -(w - 5)
w - 8 ≤ -w + 5
w - 8 + w ≤ -w + 5 + w
2w - 8 ≤ 5
2w - 8 + 8 ≤ 5 + 8
2w ≤ 13
2w/2 ≤ 13/2
w ≤ 13/2

How much commission will George receive for the sale of a $250,000 home if he receives 2 1/2% of the selling price?
Answers
Answer:
625,000
Step-by-step explanation:
250,000 * 5/2 = 625,000
The commission that George will receive for the sale of a [tex]\$[/tex]250,000, if he receives 2 1/2% of the selling price is $6,250.
What is commission?"A commission is a piece of work that someone is asked to do and is paid for."
Sale is [tex]\$[/tex]250,000
Converting 2 1/2% in improper fraction is 5/2 %
So, commission will be [tex]\(2.5*250,000 /100[/tex] = 625,000/100 = 6250
Hence, the commission that George will receive is $6,250.

What is -1 7/8 + -2 1/4? Please explain why and a step by step :).
Answers
Answer:
-33/8= -4 1/8= -4.125
Step-by-step explanation:
step 1: Add (-1 7/8) + (-2 1/4)= -33/8
Step 2: convert the mixed number to improper fraction
− 1 7/8 = (1x8/8 + 7/8) = - 8+7/8 = -15/8
Step 3: Add a negative
-15/8 +(-9/4) = -15/8 - 9/4
Adding a negative is the same as subtracting a positive btw
step 4: Find the common denominator
-15/8 - 9/4 = -15x1/8x1 - 9x2/4x2 = -15/8 -18/8
8 is the least common multiple of denominators 8 and 4. Use it to convert to equivalent fractions with this common denominator.
step 5. Simplify
-33/8 = -4 1/8
A. Simplify, sub-step a: Reduce fraction to lowest terms.
Reduce fraction to lowest terms
1 is the greatest common divisor of 33 and 8. The result can't be further reduced.
B. Convert improper fraction to mixed number
-33/8 = 04 1/8
33 ÷ 8 = 4 remainder 1
Answer:
The solution is -4 1/8 or -33/8
Step-by-step explanation:
[tex] \sf - 1\frac{7}{8} + ( - 2 \frac{1}{4} ) \\ \\ = \sf - \frac{15}{8} - \frac{9}{4} \\ \\ = \sf \frac{ - 15 - 9(2)}{8} \\ \\ = \sf \: = \frac{ - 15 - 18}{8} \\ \\ = \sf - \frac{33}{8} \\ \\ = \sf - 4 \frac{1}{8} [/tex]
