Answer:
See answer below.
Step-by-step explanation:
P(v) = -4v³ + 12v² - 9v
Point (-5, -845) is not a point on the graph
P(-5) = -4(-5)³ + 12(-5)² - 9(-5)
P(-5) = 500 + 300 + 45
P(-5) = 800 + 45
P(-5) = 845 point (-5, 845) is a solution

Nvm i messed up my math
in a class of 40 students, only 20% of the students are participating in an art competition. how many students are not taking part in the competition?
======================================================
Explanation:
There are two approaches.
Method 1)
20% of 40 = 0.20*40 = 8
Since 8 students are participating, this means 40-8 = 32 are not participating.
-----------
Method 2)
20% are participating, so 100% - 20% = 80% are not participating
80% of 40 = 0.80*40 = 32
Consider the following system of equations. Line 1: x + y = -2 Line 2: 3x - y = 2 Part A: The ordered pair (-4, 2) is a solution to O Line 1. O Line 2. o the system of equations.
Answer:
(a) Line 1
Step-by-step explanation:
The given point is only a solution to the equation for Line 1. This is shown in the attached graph.

You can put those values into each equation to see if it is satisfied.
1: -4 +2 = -2 . . . . this equation is satisfied.

PLEASE HELP ME GET ANSWER
Answer:
The second number is 90.
Step-by-step explanation:
The first statement isn't at all helpful when you start the problem. Three numbers add up to 185. Big deal. Hold that thought for later.
You need a place to start: think about some quantity to assign a variable name (letter) to. Look at the second statement.
The second number is 5 times the first. If x represents the first number, then 5 times that is 5x. So far, you have this:
x = first number
5x = second number
Next: The third number is 13 less than the second number. "13 less than" means to subtract 13 from something. But what? The second number.
5x - 13 = third number
Now the first statement is useful. All three numbers add up to 185.
x + 5x + (5x - 13) = 185
Combine like terms.
11x - 13 = 185
Add 13.
11x = 198
Divide by 11.
x = 18
Wait! Trick question. The problem asks for the second number, not the first.
5x = 5(18) = 90

Answer:
Step-by-step explanation:
How much does a sandwich and drink cost together?
($0.79 + $2.49) = $3.28
How many can he buy with $45.00?
$45/$3.28 = 13.72 or 13 sandwich/soda combos.
13 soft drinks and
13 sandwiches
How much change will Jason get?
$45 - 13($3.28) = $2.36

One angle of a right triangle measures 36. 5 degrees. What is the measure of the other small angle?.
Answer:
The other small angle is 53.5 degrees
Step-by-step explanation:
We know that a right triangle has to have a 90 degree angle and 2 other small angles.
All triangles when adding up all of their "degrees" has tp equal 180 degrees.
Since we know that there is a 90 degree angle and a 36.5 degree angle.
All we have to do is add 90 plus 36.5, then subtract that sum onto 180.
90 + 36.5 = 126.5
180 - 126.5 = 53.5
So the answer is 53.5 degrees.
Hope this helps! :)

A right triangle is a triangle in which the angles sum up to 180 degrees. It is made up of three sides : the height, the base and the hypotenuse. One of the angles in a right triangle has a value of 90 degrees.
Missing angle = sum of angles in a triangle - (sum of the two given angles)
Missing angle = 180 - ( 90 + 36.5)
180 - 126.50
= 53.5 degrees

Answer:
enlargement: >1reduction: <11: same sizeStep-by-step explanation:
The scale factor of an enlargement is greater than 1.
The scale factor of a reduction is less than 1.
A scale factor of 1 will produce a congruent figure, one the same size as the original.
_____
A longer way to say it
A figure is enlarged when its dimensions are greater than those of the original. Then the ratio of dimensions will be ...
(greater than original)/(original) = greater than 1
Similarly, a figure is reduced when its dimensions are less than those of the original:
(less than original)/(original) = less than 1
Multiplying dimensions by a scale factor of 1 does not change them. The scaled figure is the same size as the original.

The sum of two polynomials is â€"yz2 â€" 3z2 â€" 4y 4. If one of the polynomials is y â€" 4yz2 â€" 3, what is the other polynomial? â€"2yz2 â€" 4y 7 â€"2yz2 â€" 3y 1 â€"5yz2 3z2 â€" 3y 1 3yz2 â€" 3z2 â€" 5y 7.
The sum of polynomials involves adding the polynomials
The other polynomial is [tex]y^3 -y^2+ 4y - 1[/tex]
The sum of the polynomials is given as:
[tex]Sum = y^3 + 3y^2 + 4y - 4[/tex]
One of the polynomials is given as:
[tex]P = 4y^2 - 3[/tex]
Represent the other polynomial with Q.
So, we have:
[tex]P +Q =Sum[/tex]
Substitute the expressions for P and Sum
[tex]4y^2 - 3 +Q =y^3 + 3y^2 + 4y - 4[/tex]
Make Q the subject
[tex]Q =y^3 + 3y^2 -4y^2+ 4y - 4 +3[/tex]
Evaluate like terms
[tex]Q =y^3 -y^2+ 4y - 1[/tex]
Hence, the other polynomial is [tex]y^3 -y^2+ 4y - 1[/tex]
