Answer:
x=6
Step-by-step explanation:
Since the line is vertical, it has no slope. This means that it will only go through points that have an x-coordinate of 6.
Write a polynomial function in standard form with zeros at 0, 1, and 2.
f(x) = x(x - 1)(x - 2)
f(x) = x(x + 1)(x + 2)
f(x) = x3 – 3x2 + 2x
f(x) = x3 + 3x2 + 2x

Marisol noticed that she does not have a common factor.
Which accurately describes what Marisol should do
next?
Marisol grouped the terms and factored the GCF out of
the groups of the polynomial 6x3 - 22x2 - 9x + 33. Her
work is shown.
Step 1: (6x3 – 22x2) - (9x + 33)
Step 2: 2x²(3x – 11) - 3(3x + 11)
O Marisol should realize that her work shows that the
polynomial is prime.
O Marisol should go back and group the terms in Step 1
as (6x3 - 22x2 - (9x - 33).
O Marisol should go back and group the terms in Step 1
as (6x3 – 22x2) + (9x - 33).
Marisol should refactor the expression in Step 2
as 2x²(3x + 11) - 3(3x + 11).
Answer: option 2 describes best
Step-by-step explanation:Given Marisol grouped the terms and factored the GCF out of the groups of the polynomial 6x3 – 22x2 – 9x + 33. Her work is shown.
Step 1: (6x3 – 22x2) – (9x + 33)
Step 2: 2x2(3x – 11) – 3(3x + 11)
Marisol noticed that she does not have a common factor. Which accurately describes what Marisol should do next?
Marisol should realize that her work shows that the polynomial is prime.
Marisol should go back and group the terms in Step 1 as (6x3 – 22x2) – (9x – 33).
Marisol should go back and group the terms in Step 1 as (6x3 – 22x2) + (9x – 33).
Marisol should refactor the expression in Step 2 as 2x2(3x + 11) – 3(3x + 11).
According to question Marisol grouped the terms and has done factorisation of the given polynomial 6x^3 – 22x^2 – 9x + 33.
In step 1 she has written as (6x^3 – 22x^2) – (9x + 33)
Marisol has to go to step 1 in order to correct her mistake. She has to group the expression as (6x^3 – 22x^2) – (9x – 33) so that she will be able to get the expression as
6x^3 – 22x^2 – 9x + 33 after opening the brackets.
The accurately describes what Marisol should do next will be;
⇒ Marisol should go back and group the terms in Step 1,
as (6x³ - 22x²) - (9x - 33)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Marisol noticed that she does not have a common factor.
And, Her work is shown.
Step 1: (6x³ - 22x²) - (9x + 33)
Step 2: 2x²(3x – 11) - 3(3x + 11)
Now,
Since, The polynomial is,
⇒ 6x³ - 22x² - 9x + 33
And, Her work is shown.
Step 1: (6x³ - 22x²) - (9x + 33)
Step 2: 2x²(3x – 11) - 3(3x + 11)
Clearly, She make mistake on step 1 as to take negative sign common.
Hence, The accurately describes what Marisol should do next is;
⇒ Marisol should go back and group the terms in Step 1,
as (6x³ - 22x²) - (9x - 33)

do you guys know whats the correct classification of 3 over 8?
Answer: 3/8
Step-by-step explanation:
The principal on Jan’s loan was $4,700, but by the time she had paid it off after four years, the interest and principal totaled $5,388. If Jan made regular quarterly payments of $355 until the loan was paid off, how much did Jan pay for service charges?
Answer:
$292 in fees
Step-by-step explanation:
First, calculate the total payments Jan made over the 4 years
$355 x 4 payments per year x 4 years = $5,680
Then, calculate the total payments made and subtract the amount of Principal and Interest paid from the total payments made.
$5,680 - $5,388 = $292
$292 is the FEE for the loan
$4,700 is the PRINCIPAL for the loan
$688 is the INTEREST for the loan
Answer:
The answer is 292

Find the critical point of the function f(x) = x2 – 2x + 7.
Answer:
[tex]x=1[/tex] is a critical point of the function [tex]f(x).[/tex]
Step-by-step explanation:
[tex]f(x)=x^2-2x+7[/tex]
Differentiate both sides w.r.t. [tex]x[/tex]
[tex]\Rightarrow f'(x)=2x-2[/tex]

Is 1/4 and 4/16 an equivalent fraction? If so why ?
Answer:
Yes
Step-by-step explanation:
1/4 = 4/16 because 1/4 of 16 is 4
Also,
1/4 is just a simplified version of 4/16
The answer to whether 1/4 and 4/16 are equivalent fractions is that; Yes, they are equivalent fractions
How to simplify Fractions?We have two fractions which are; 1/4 and 4/16
Now, the first fraction is already in simplified form and can't be simplified further. However, the second fraction can be further simplified.
For the second fraction which is 4/16, the numerator and denominators have a common term which is 4. Thus, we can factor it out to get;
(4/4) * (1/4)
4/4 =1 and so we see that 4/16 can be reduced to the first fraction and so they are the same.

solve for y 4y-36x=28
Answer:
[tex]y = 9x + 7[/tex]
Step-by-step explanation:
To solve for y, our goal is to get it isolated on one side of the equation.
[tex]4y - 36x = 28[/tex]
Let's add [tex]36x[/tex] to both sides of the equation.
[tex]4y = 36x + 28[/tex]
Now divide both sides by 4.
[tex]y = 9x + 7[/tex]

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The number of planes that land every 8 minutes = 4 planes
The number of planes that land every minute =
The number of planes that land every 8 minutes / 8
The number of planes that land every minute = ( 4 / 8 ) planes
= 1/2 plane
Now ,
1 hour = 60 minutes
The number of planes that land every hour =
The number of planes that land every minute x 60
The number of planes that land every hour = ( 1/2 ) x 60
= 30 planes
Hence , the number of airplanes that land every hour is 30 airplanes

A certain pickup truck gets 20mpg in the city and 28 mpg on the highway. If the driver drives 270 mi on 11 gal of gas, determine the number of city miles and highway miles that the truck was driven
Answer:
95 city and 175 highway miles.
Step-by-step explanation:
The driver gets 20 mpg in city, and 28 mpg on the highway.
An equation that could be written is
20x+28y=270
This equation accounts for the distance traveled.
x+y=11
This equotion accounts for how many gallons were driven.
Multiply the bottom equation by 20, so you can solve the set of equations.
20x+28y=270
20x+20y=220
subtract them
8y=50
y=6.25
now plug this back into x+y=11
x+6.25=11
x=4.75
Now 4.75×20=95 city miles and 6.25×28=175 highway miles.

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 85 miles per hour. The eastbound train travels 105 miles per hour. How long will it take for the two trains to be 456 miles apart? Do not do any rounding.
Answer:
Step-by-step explanation:
We'll make a table for this since we have 2 different trains for which we have formulas. We'll use the distance = rate * time formula, but we have to use it twice because we have 2 trains, then we have to come up with an equation that incorporates both of the distances of the 2 trains to come up with a time. Easy.
d = r * t
East train
West train
Now we can fill in. We know that the rate of the east train is 105 and the rate of the west train is 85, so we fill that in:
d = r * t
East train 105
West train 85
The time is what we are looking for, so that is the unknown for each train:
d = r * t
East train 105 t
West train 85 t
Since the formula is d = rt, we will multiply the rates of each times the time of each and fill in accordingly:
d = r * t
East train 105t 105 t
West train 85t 85 t
Here's an illustration to the best of my abilities in this forum:
<------------------------------|----------------------->
85t 105t
|----------------------456 miles-------------------|
The illustration is supposed to show you that the distance between the trains (456 miles) is found by adding the 2 distances together and solving for t:
85t + 105t = 456
190t = 456 so
t = 2.4 hours
