Answer:
x³ - 3x² - 9x + 27
= x²(x - 3) - 9(x - 3)
= (x² - 9)(x - 3)
= (x -3)(x + 3)(x - 3)

Andy runs 436.8 meters in 62.08 seconds. If Andy runs at a constant speed, how can we find out how far he runs in each second? Explain what is happening mathematically to the decimal points in the divisor and dividend before dividing. Do not solve, just explain how you would begin to set up your problem. *
Answer:
7 meters per second.
Step-by-step explanation:
Given that,
Andy runs 436.8 meters in 62.08 seconds.
We need to find how far he run in each second. It can be calculated by dividing distance by time taken as follows :
[tex]x=\dfrac{436.8\ m}{62.08\ s}\\\\=7.03\ m/s[/tex]
or
x = 7 m/s
So, Andy will cover 7 meters per second.

Given f(x) = -4x2 +13x-2, what is the value of f(-1)?
Answer:
f(- 1) = - 19
Step-by-step explanation:
To evaluate f(- 1) substitute x = - 1 into f(x) , that is
f(- 1) = - 4(- 1)² + 13(- 1) - 2 = - 4(1) - 13 - 2 = - 4 - 13 - 2 = - 19
whats the equation for a line thats perpendicular to 6x-2y=8 when it passes through (6,-5)
( i hope i wrote that right sorry)
Answer:
Equation of required line is: [tex]\mathbf{x+3y=-9 }[/tex]
Step-by-step explanation:
We need to find equation for a line that's perpendicular to [tex]6x-2y=8[/tex] when it passes through (6,-5)
We will use the slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
Finding Slope m:
When two lines are perpendicular there slopes are [tex]m=-\frac{1}{m}[/tex]
Finding slope of given equation first: [tex]6x-2y=8[/tex]
Writing in slope-intercept form:
[tex]6x-2y=8\\-2y=-6x+8\\y=\frac{-6x}{-2}+\frac{8}{-2}\\y=3x-4[/tex]
Comparing it with slope intercept form: [tex]y=mx+b[/tex] , m= 3
So, slope of given equation is 3
Now, the slope of required equation will be [tex]m=-\frac{1}{m}[/tex]
So, Slope m=-1/3
Finding y-intercept
Using slope m=-1/3 and point (6,-5) we can find y-intercept
[tex]y=mx+b\\-5=\frac{-1}{3}(6)+b\\-5=-2+b\\b=-5+2\\b=-3[/tex]
So, y-intercept is b=-3
Now, finding the equation of required line having Slope m=-1/3 and y-intercept b= -3
[tex]y=mx+b\\y=-\frac{1}{3}x-3[/tex]
Writing in standard form:
[tex]y=-\frac{1}{3}x-3\\y=\frac{-x-9}{3}\\3y=-x-9\\x+3y=-9[/tex]
So, equation of required line is: [tex]\mathbf{x+3y=-9 }[/tex]
Explain why the sum of the angle measures in any triangle is 180
Answer:
Step-by-step explanation:
Because every triangle that can ever be made has three sides, you can open up the triangle so that it becomes a straight horizontal line. A horizontal line is also 180 degrees which is why this idea works with triangles.
The reason for the sum of the angles in any triangle is 180 is that when we open up the sides of a triangle we get a straight line where the angle of a straight line is 180 degrees.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles has are equal to 180 degrees.
We have,
The sum of the angle measures in any triangle is 180.
We see that,
In a triangle, there are three sides and three angles.
If we open up the triangle, we see that the three sides of the triangle form a straight line.
The angle of a straight line is 180 degrees.
Thus,
The reason for the sum of the angles in any triangle is 180 is that when we open up the sides of a triangle we get a straight line where the angle of a straight line is 180 degrees.

Tyler gather data and notices that the number of crimes in Glendale and the number of students enrolled in schools have a strong positive correlation tell a proposes closing down schools as a solution to reduce or illuminate crime in Glendale what do you recommend to the Glendale city Council
Answer:
The fact that the number of crimes and the population of students is positively correlated, means that as the total number of students increases, so does the total number of crimes.
The conclusion that closing schools will decrease crime is absurd. First of all, the variables might be totally unrelated, e.g. places with large number of students are places that have high populations. Higher crime rate are generally linked to neighborhoods or cities with high populations.
The idea of closing schools to fight crime is foolish because it will result in the opposite. Generally, students who go to school tend to be less engaged in criminal activities. The real problem here is that you should try to increase the number of students that attend schools in Glendale, not vice versa.

The water level in Ricky Lake changes at an average of -716 inch every 3 years. a. Based on the rate above, how much will the water level change after one year? Show your calculations and you can use the vertical number line to help you., using 0 as the original water level.
Answer:
The water level will change at a rate of - 2 7/18 inches per year
Step-by-step explanation:
From the question, we have a change of -7 1/6 inch every 3 years
We now want to calculate the value of the change every year
Mathematically, that will be;
- 7 1/6 divided by 3
= -43/6 divided by 3
= -43/18 = - 2 7/18 inch per year

Jenny solved the equation 1 – (2x + 4) = –4x + 5. Her work is shown. 1 − ( 2 x + 4 ) = − 4 x + 5 Line 1: 1 − 2 x + 4 = − 4 x + 5 Line 2: 5 − 2 x = − 4 x + 5 Line 3: 2 x = 0 Line 4: x = 0 What is the correct solution to the equation 1 – (2x + 4) = –4x + 5? Re-solve the equation to find the correct solution.
Answer:
4Step-by-step explanation:
Given the equation 1 – (2x + 4) = –4x + 5, we are to find the correct solution of the equation;
Step 1: Open the parenthesis;
1 – (2x + 4) = –4x + 5
1-2x-4 = -4x + 5
1-4-2x = -4x +5
-3-2x = -4x + 5
Step 2: Collect like terms
-2x + 4x = 5 + 3
2x = 8
Step 3: divide both sides by 2;
2x/2 = 8/2
x = 4
Hence the correct value of x is 4
