The graph of f(x) = x2 − 3x − 28 is shown. Which of the following describes all solutions for f(x)?
a parabola passing through negative 4 comma zero, zero comma negative 28, and 7 comma zero
(−4, 0), (0, −28), (7, 0)
(−4, 0), (−1, −24), (0, −28), (3, −28), (7, 0)
(x, x2 − 3x − 28) for all real numbers
(x, y) for all real numbers
Answer:
C. (x, x2 − 3x − 28) for all real numbers
Function graphs are graphs of solution equations for y! In this instance, f(x) = x² -3x -28 is the graph.
Constructing a Function Graph:⇒f(x) = x² − 3x − 28
A group of all points in the plane of the form (x, f(x)) constitutes the diagram of a function f. The graph of f can also be defined as the graph of an equation y = f(x). As a corollary, a function's graph is a subset of an equation's graph.
Solving equation:
⇒f(x) = x² − 3x − 28
⇒f(x) = x² − (7−4)x − 28
⇒f(x) = x² − 7x+4x − 28
⇒f(x) = x(x −7) +4(x −7)
⇒f(x) = (x −7) (x+4)

Step-by-step explanation:
2/3+3/5
=10+9/15
=19/15
The mistake she made was that she didn't took right LCM.
The value of the fraction 2/3 + 3/5 is 19/15.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
2/3 + 3/5
= (10 + 9)/15

Explanation:
For each row, divide the earnings over the sales.
In row 1, we have 22/673 = 0.0327 approximately In row 2, we have 37/1298 = 0.0285 approximately In row 3, we have 101/3277 = 0.0308 approximately In row 4, we have 150/5180 = 0.0290 approximatelyAll of these decimal values have the following conversions to percentages
0.0327 = 3.27% 0.0285 = 2.85% 0.0308 = 3.08% 0.0290 = 2.90%If we add up those percentages and divide by 4, we get the average percentage
(3.27+2.85+3.08+2.90)/4 = 3.025
So the average percentage of these four is 3.025%
So for instance, if you made $1000 in sales, then 0.0325*1000 = 32.50 would be the estimated earnings.
A good estimate in my opinion is the equation c = 0.0325d since 3.025% converts to the decimal form 0.0325
Another method you could use is linear regression to help estimate. Though this method is a lot more complicated involving many more steps. It's better to use technology (eg: graphing calculator) if you go this route. The linear regression line is approximately y = 0.02896x + 2.00732; we can see the slope 0.02896 isn't too far off from 0.0325. Other forms of regression are possible as well.

Latrell wants to fill his water bottle between classes, but the water fountain next to his classroom is frustratingly slow. It takes Latrell 5 seconds to get each ounce of water in his bottle. There is a proportional relationship between the amount of water (in ounces) Latrell puts in his water bottle, x, and how long in seconds) it takes to get that amount, y. Graph this relationship. Select two points to draw a line.
what is the slope of the line? _____
Answer:
Step-by-step explanation:
Slope = rise/ run, or y∨2 - y∨1/ x∨2 - x∨1
5-10/ 1-2 =
-5/-1 = 5
The slope of the line drawn from the given data is 5.
What is the slope?A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).
Given this, Latrell fills his bottle with one ounce of water in five seconds. The amount of water Latrell puts in his water bottle (in ounces), x, and the time (in seconds) it takes to get that amount, y, are proportionate. This connection can be graphed. Since, the line will pass from the origin(0, 0).
Since given y is the directly proportional equation of the line will be;
y = mx
where m is the slope of the line
Also given, filling the bottle at every ounce requires 5 seconds of time. hence, the line will go from (1, 5)
Thus, the value of the m will be;
5 = m *1
m =5
Therefore, the slope of the line is 5.

A phone company charges $67 for monthly access and $14 for each gigabyte of data used. If you sign a two-year contract and use 147.5 gigabytes of data, what is the total amount you will pay for phone service?
Answer:
the answer is below :)
Step-by-step explanation:
BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y. ($120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x to find where the gigabytes are the same.
100 + 10x = 120 + 5x
Subtract 100 from both sides: 10x = 20 + 5x
Subtract 5x from both sides: 5x = 20.
Divide both sides by 5: x = 4. 4 gigabytes is the answer.
a brainliest would be appreciated :)
The total amount you will pay for phone service is 4 gigabytes.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
BigBytes will be 100 +10x = y
Therefore , We have $100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y.
We have $120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x;
100 + 10x = 120 + 5x
Now Subtract 100 from both sides:
10x = 20 + 5x
Then Subtract 5x from both sides:
5x = 20.
Now Divide both sides by 5:
x = 4.
Hence, the total amount you will pay for phone service is 4 gigabytes.

6x +10x -40 = 12
16x = 12 +40

3.(x + 2) + (2x + 3) = 23
Answer:
x = 6
Step-by-step explanation:
(x + 2) + (2x + 3) = 23
Combine like terms
3x +5 = 23
Subtract 5 from each side
3x+5-5 = 23-5
3x = 18
Divide each side by 3
3x/3 = 18/3
x = 6
Answer:
x = 6
Step-by-step explanation:
1. Remove parentheses where unneeded. x + 2 + 2x + 3 = 23
2. Add constants. x + 5 + 2x = 23
3. Combine like terms. 3x + 5 = 23
4. Subtract "5" from the constants on both sides of the equation. 3x = 18
5. Divide both sides by 3. 3x/3 = 18/3
6. Simplify. x = 6

Answer:
1. y ≥ 100
2. y ≤ 300
3. y ≥ 20000
4. 2y ≥ 80
5. 2y ≤ 90
Step-by-step explanation:
Let y be the variable.
1. The discount is not less than 100.
If the discount (i.e y) is not less than 100, it means it is either 100 or greater than 100.
This can be written as:
y ≥ 100
2. The cost of the book is at most 300.
This implies that the cost of the book (i.e y) is either 300 or lesser.
This can be written as:
y ≤ 300
3. His monthly income is at least 20000. This simply means that his monthly income (i.e y) is 20000 or greater than 20000.
This can be written as:
y ≥ 20000
4. Twice the number is at least 80.
Let the number be y.
Twice the number y can be written as:
2y
But twice the number is at least 80.
This means that twice the number is 80 or greater than 80. This can be written as:
2y ≥ 80
5. Twice the measure of the acute angle is not more than 90 degree.
Let the angle be y.
Twice the angle can be written as:
2y
But twice the measure of the angle is not more than 90 degree. This implies that twice the angle is 90 or lesser than 90. This can be written as:
2y ≤ 90
