Answer: I'm guessing it would be a parabola, with the line going through -6 on the y-axis and passing through 2 and 6 on the x-axis, but we cannot see any answers, so therefore we can't answer it accurately.
Step-by-step explanation:
Since the the graph is not given it can be identified by the graph passing through the three coordinate points given.
What are coordinates of a graph?Each point can be identified by an ordered pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate. Ordered pairs are written in parentheses (x-coordinate, y-coordinate). The origin is located at (0,0).
We have a function that has a y-intercept of -6 and x-intercepts at (2,0) and (6,0).
Since, the graph is not given it cannot be identified clearly what would be the possible graph. But the following points can be concluded -
The graph of the function will cut the y - axis at y = -6.The graph of the function cuts the x - axis at two points i.e. at x = 2 and at x = 6.Any graph passing through the 3 points will be the required graph.

In the figure above AB = 4x + 6 and BC = 7x + 15. If AC = 120, find the length of segment AB.
Answer:
x = 9
Step-by-step explanation:
AB = 4x + 6 and BC = 7x + 15 AC is the sum of AB and BC
so 4x + 6 + 7x + 15 = 120 add like terms
11x + 21 = 120 subtract 21 from both sides
11x = 99 divide both sides by 11
x = 9

The ratio of cassettes tapes to compact discs is 5 to 2, and the number of cassette tapes is 10 less than 5 times the number of compact discs. How many cassette tapes are there
There are 4 cassette tapes.
Given that,
Let x be the number of compact discs
Then 5 times the number of CD's= 5x and 10 less than 5 times the number of CDs is 5x-10
Therefore the number of cassettes is 5x-10
Now we are told that the ratio of cassettes to CDs which is
((5x-10)/x) equals 5/2 so our equation to solve is:
(5x-10)/x=5/2 multiply both sides by 2x to get rid of the fractions and we get:
2(5x-10)=5x
Further solving this equation, we get:
10x-20=5x
5x=20
x= 4 (number of compact discs)
Thus, there are in total 4 cassette tapes.

An item costs $430 before tax , and the sales tax is $34. 40. Find the sales tax rate. Write your answer as a percentage
The sales tax rate on the item = 8%
We know that the sales tax is nothing but the purchase price times the percentage of tax.
An item costs $430 before tax.
This means, the purchase price is 430 dollars.
The sales tax is $34. 40
To find: the sales tax rate as a percentage
First we find a ratio of the sales tax to the cost of the items before tax.
Sales tax / Pre-tax value of item = (34.40) / 430
Now we write a proportion where the pre-tax value is proportional to 100% and solve for the percentage of sales tax.
i.e., (34.40) / 430 = sales tax percent / 100
So, the sales tax percent = 8%
Therefore, the sales tax is of 8%

How do you know if a triangle is right acute or obtuse?
if a²+b²>c², the triangle is acute, if a²+b2²=c², the triangle is a right triangle, and if a²+b²<c², the triangle is obtuse.
where a and b are the lengths of the two shorter sides of the triangle and c is the length of the longest side.
A right-angled triangle is a triangle with one of the angles at 90 degrees. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle.
An acute triangle has three angles that each measure less than 90°. In an acute-angled triangle, all three internal angles of the triangle are acute, that is, they measure less than 90°.
An obtuse triangle is a triangle with one angle that is greater than 90° degrees, it is not possible for a triangle to have more than one obtuse angle.

Your grandmother has given you some money, and now you plan to save what she has given you along with a certain amount of money each week. After 17 weeks, you have $570, and after 29 weeks, you have $822. a) Find an equation (in slope-intercept form) of the amount of money saved after × weeks.
An equation in slope-intercept form of the amount of money saved after x weeks is y=21x+213.
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
Given that, after 17 weeks, you have $570, and after 29 weeks, you have $822.
Here, (17, 570) and (29, 822)
Substitute (x₁, y₁)=(17, 570) and (x₂, y₂)=(29, 822) in m=(y₂-y₁)/(x₂-x₁)
= (822-570)/(29-17)
= 252/12
= 21
Substitute, m=21 and (x, y)=(17, 570) in y=mx+c, we get
570=21×17+c
570=357+c
c=213
Substitute, m=21 and c=213 in y=mx+c, we get
y=21x+213
Therefore, an equation in slope-intercept form of the amount of money saved after x weeks is y=21x+213.

Carlos accepts a new job with a starting salary of $46,000. He will earn a 5% increase after each year. What will be his salary after 3 years?
$46,000 • 1.05 • 3 = $144,900 is Carlos’ salary after 3 years.
Answer:
What he did right was doing the first part correctly, wher it;s 46000x1.05, which is 48300. But then the student thought that every year, Carlos' salary will increase by 48300, and after 3 years it got to 144900, which is nuts. The real thing is to do 46000 x 1.15, because on the 3rd year, your salary will be 115% of your salary, if that makes sense, you do 5x3 = 15, then you add 15% to 100 which is 115 % =1.15. then you do 46000x1.15= 55545$

Carlos accepts a new job with a starting salary of $46,000. He will earn a 5% increase after each year. What will be his salary after 3 years.
It is defined as the fee you pay to borrow money or the fee you levy to lend money. Interest is considerable and frequently recalled as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
Incorrect solution,
$46,000 • 1.05 • 3 = $144,900 is Carlos’ salary after 3 years.
Correct solution,
Principal amount = $46,000
rate of increase in salary each year = 5%
After t = 3 years what will be the salary = ?
following identity is used to calculate the increments in principal amount.
[tex]Amount = principal(1+r)^t[/tex]
[tex]Amount = 46000(1+0.05)^3\\Amount = 46000(1.05)^3\\[/tex]
Amount = 456000 * 1.16

f(x) = 2x^2 – 3x – 9
g(x) = 4x^2 - 9
Find ( f/g)(x).
Answer:
(f/g)x = (x - 3)/(2x - 3)
Step-by-step explanation:
Try and see if f(x) can be factored.
g(x) = (2x - 3) (2x + 3)
That means that perhaps f(x) has one of these two factors.
(2x 3)(x 3)
You want the 2x and 3 to multiply. The middle term has to be -, so when 2x and 3 multiply likely it is 3 that gives you the minus answer.
(2x + 3)(x - 3) should be the way f(x) factors, and it is.
f(x) / g(x) = (2x + 3) (x - 3)
(2x + 3)(2x - 3)
2x + 3 cancels. The answer is
(f/g)x = (x - 3)/(2x - 3)
A small snowcone costs $0.75 at the local snowcone shack. Mrs. Eckelberry had the snowcone shack deliver small snowcones for some of her students. She spent $18.75 for the snowcones. The equation 0.75s = 18.75 could be used to determine how many snowcones were ordered. How many snowcones did Mrs. Eckelberry order? * 16 pointsss!
Answer:
25 snowcones
Step-by-step explanation:
0.75s = 18.75, where (s) is the number of students/snowcones ordered
Divide both sides by 0.75:
0.75s/0.75 = 18.75/0.75

How many solutions does the system y 3x 4 and 6x 2y 8 have?
The system y = 3x + 4 and 6x - 2y = 8 has no solutions.
A system of equations is a set of equations with multiple variables. To determine the number of solutions for a system of equations, one can use the following methods: graphing, substitution, or elimination. In this case, we can use the elimination method by adding or subtracting the equations to eliminate one of the variables.
If we add the two equations, we get y = 3x + 4 + 6x - 2y = 8, which results in 3x + 4 = 8. This is an inconsistent equation and does not have any solutions. Therefore, the system y = 3x + 4 and 6x - 2y = 8 has no solutions.
This shows that the system is inconsistent, which means that there's no solution that satisfies both equations.
