Question 10 multiple choice
Answer: Choice B
(x-1)(x^3+x^2+5x+6)
==========================================
Explanation:
The 1 in the upper left box means that x = 1 is a root of the original polynomial.
So this means x-1 is a factor of the original polynomial.
This is because x = 1 leads to x-1 = 0 after subtracting 1 from both sides.
-----------------
The 0 in the last position of the bottom row shows we got a remainder of 0.
Getting a remainder 0 tells us that (x-1) is a factor of the polynomial. This synthetic division table confirms our initial guess.
The other values in that bottom row (1, 1, 5, 6) form coefficients to the polynomial 1x^3+1x^2+5x+6, or simply x^3+x^2+5x+6
-------------------
So we know that (x-1) and (x^3+x^2+5x+6) are factors
Meaning that,
x^4+4x^2+x-6 = (x-1)(x^3+x^2+5x+6)
You can confirm this by expanding out the right hand side (distribution rule).
find the equation of the line which passes through the point (7,2) and is perpendicular to y=5x-2
Answer:
[tex]\displaystyle y=-\frac{1}{5}x+\frac{17}{5}[/tex]
Step-by-step explanation:
Equation of a line
A line can be represented by an equation of the form
[tex]y=mx+b[/tex]
Where x is the independent variable, m is the slope of the line, b is the y-intercept and y is the dependent variable.
We need to find the equation of the line passing through the point (7,2) and is perpendicular to the line y=5x-2.
Two lines with slopes m1 and m2 are perpendicular if:
[tex]m_1.m_2=-1[/tex]
The given line has a slope m1=5, thus the slope of our required line is:
[tex]\displaystyle m_2=-\frac{1}{m_1}=-\frac{1}{5}[/tex]
The equation of the line now can be expressed as:
[tex]\displaystyle y=-\frac{1}{5}x+b[/tex]
We need to find the value of b, which can be done by using the point (7,2):
[tex]\displaystyle 2=-\frac{1}{5}*7+b[/tex]
Operating:
[tex]\displaystyle 2=-\frac{7}{5}+b[/tex]
Multiplying by 5:
[tex]10=-7+5b[/tex]
Operating:
[tex]10+7=5b[/tex]
Solving for b:
[tex]\displaystyle b=\frac{17}{5}[/tex]
The equation of the line is:
[tex]\boxed{\displaystyle y=-\frac{1}{5}x+\frac{17}{5}}[/tex]
Help Geometry im very stupid
Its an obtuse triangle because one of the angle n is 98 degrees
Answer:
Obtuse Triangle
Step-by-step explanation:
First we have to find the measure of all the angles. We know that the sum of all angles in a triangles is 180 degrees.
So we add 35 and 47 which is 82 degrees.
Then we subtract 82 from 180 which is 98 degrees. Now we know that angle N is 82 degrees.
We can go ahead eliminate answer choices acute equiangular triangle (that only applies if all angles are 60 degrees) and right triangle (must have a right angle which is 90 degrees).
That now leaves us with acute and obtuse triangle. An acute triangle has angles that are less that 90 degrees. So that only leaves us with the answer choice obtuse triangle, because it has an angle of 98 degrees which is an obtuse angle.
So your answer is Obtuse Triangle.
Stacy and Neil painted 280 square feet of their living room wall with 4/5 gallon of paint. How many square feet can they paint with 3 gallons of paint?
Answer:
280 square feet can be painted with .8 gallons and (280 / .8) or 350 square feet can be painted with 1 gallon and with 3 gallons you could paint 1,050 square feet.

I need Urgent Help!! Can you please show me how you solve this step by step? 4-7x>-5(4+x)
Answer:
The answer of this inequality is: x < 12
Step-by-step explanation:
1) First, place out what is given:
[tex]4 - 7x>-5(4+x)[/tex]
2) Distribute -5 to (4 + x)
[tex]4 - 7x > -20-5x[/tex]
3) We want to get x by itself, so we need to move each term to their own side(s):
4 - 7x > - 20 - 5x
+20 + 7x > +20 +7x
---------------------------
24 > 2x
5) Divide both sides by 2
[tex]\frac{24}{2} > \frac{2x}{2}[/tex]
6) Now that you have x alone, your answer is:
[tex]x < 12[/tex]
(I changed the position of x which is why the sign turned around)

Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving at a constant rate of 50 mi/h. Complete the function that models the distance they drive as a function of time. Then complete a reasonable domain for this situation.
function notation in slope-intercept form: f(x) = ________
reasonable domain: ≤ x ≤
Answer: The function that models the distance they drive is
f(x) = 50x + 20 where x is the time in hours
reasonable domain: 0 ≤ x ≤ 3
Step-by-step explanation:
examples:
95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.
120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.
There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t
20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.
120 = 5(2.4) The whole trip took 2.4 hours.
Can you please tell me the answer
Answer:D 45
Step-by-step explanation:I haven't done this in a long time but from my knowledge it is 45 because the triangle has to add up to 180 and you do 45+45 which will get you 90 leaving you with 2x and x would 45 as well and you would do 2 x 45= 90 and that is how you solve 2x.
But the answer to the question is 45 or D
What is the value of the slope of a line that passes through points (2,5) and (4,2)
Answer:
-3/2
Step-by-step explanation:
Using the slope formula leaves you with this
Answer:
-3/2
Step-by-step explanation:
We can find the slope of the line using
m = ( y2-y1)/(x2-x1)
= ( 2-5)/(4-2)
= -3/2
Help find the value of x
-2(4-x)=12x-3
Answer:
Step-by-step explanation:
distributive property
-8 + 2x = 12x - 3
add 3 to both sides
-5 + 2x = 12x
subtract 2x from both sides
-5 = 10x
divide by 10 for both sides
-5/10 = x
-0.5 = x
actually it's -1/2 or -0.5

Answer:
x = -3/2
Step-by-step explanation:
The removable discontinuity is at the value of x where a denominator factor cancels a numerator factor, and those factors are zero.
[tex]p(x)=\dfrac{2x+3}{4x^2-9}=\dfrac{2x+3}{(2x+3)(2x-3)}=\dfrac{2x+3}{2x+3}\cdot\dfrac{1}{2x-3}\\\\p(x)=\dfrac{1}{2x-3}\qquad x\ne-3/2[/tex]
That cancellation occurs where 2x+3 = 0, at x=-3/2.
The function p(x) has a removable discontinuity when x = -3/2.

Jaycie has a VIP membership to a movie theater, so she pays 27 dollars a year and 6.00 for each movie she sees. Claire doesn't have a membership, so she pays 8.25 for each movie she sees. How many movies would they have to see in a year in order to pay the same amount?
Answer:
12 movies
Step-by-step explanation:
Let the number of movies they see be represented by x
Jaycie has a VIP membership to a movie theater, so she pays 27 dollars a year and 6.00 for each movie she sees.
$27 + $6 × x
= 27 + 6x
Claire doesn't have a membership, so she pays 8.25 for each movie she sees.
= $8.25 × x
= 8.25x
How many movies would they have to see in a year in order to pay the same amount?
Jaycie = Claire
27 + 6x = 8.25x
27 = 8.25x - 6x
27 = 2.25x
x = 27/2.25
x = 12 movies
Therefore, they have to see 12 movies in a year in order to pay the same amount.

Find an equivalent system of equations for the following system:
x + 2y = 2
−4x + 4y = −8
a) x + 2y = 2
−4x − 2y = 10
b) x + 2y = 2
5x + 4y = 8
c) x + 2y = 2
5x − 2y = 10
d) x + 2y = 2
5x − 2y = −8
Answer:
Option C
Step-by-step explanation:
we have
x+2y=2 ------> equation A
-4x+4y=-8 ------> equation B
Multiply equation B by -1 both sides
-1(-4x+4y)=-8*(-1)
4x-4y=8 -----> equation C
Adds equation A and equation C
x+2y=2
4x-4y=8
--------------
5x-2y=10 ----> equation D
An equivalent system of equations is equation A and equation D
so
x+2y=2 ------> equation A
5x-2y=10 ----> equation D

What is the value of F in this equation
F^2=9/49
Answer:
[tex] \sqrt{f {}^{2} } = \sqrt{ \frac{9}{49} } [/tex]
[tex]f = \frac{ \sqrt{9} }{ \sqrt{49} } [/tex]
[tex]f = \frac{3}{7} [/tex] or -3/7
Answer:
[tex]f=-\frac{3}{7},\frac{3}{7}[/tex]
Step-by-step explanation:
[tex]f^2=\frac{9}{49}[/tex]
Square root both sides of the equation:
[tex]\sqrt{f^2} =\sqrt{\frac{9}{49} }[/tex]
The square root of [tex]f^2[/tex] is [tex]f[/tex], so let's rewrite the equation:
[tex]f=\sqrt{\frac{9}{49} }[/tex]
Now, we can make this easier on ourselves by noticing that both the numerator and denominator of the fraction are square numbers, so rewrite the equation:
[tex]f=\frac{\sqrt{9} }{\sqrt{49}}[/tex]
Find the square root of 9 (-3 & 3), and the square root of 49 (-7 & 7). Due to the possibility of the positive or negative solution, there will be two:
[tex]f=-\frac{3}{7} ,\frac{3}{7}[/tex]

What are the x and y intercepts for 3x-6y=-48
Answer:
x- intercept = - 16, y- intercept = 8
Step-by-step explanation:
Given
3x - 6y = - 48
To find the x- intercept, let y = 0 in the equation and solve for x
3x - 6(0) = - 48 , that is
3x - 0 = - 48 ( divide both sides by 3 )
x = - 16 ← x- intercept or (- 16, 0 )
To find the y- intercept, let x = 0 in the equation and solve for y
3(0) - 6y = - 48 , that is
0 - 6y = - 48 ( divide both sides by - 6 )
y = 8 ← y- intercept or (0, 8 )
