Find the product (4x – 2y)^3
Answer:
(2)3 • (2x - y)3
Step-by-step explanation:
Put the exponent aside and simplify the base by pulling out like factors
4x-2y = 2 • (2x-y)
Remember the 4th law of exponents : (a • b)m= am• bm
Retract the exponent and apply the 4th law to the simplified base: ( 2 • (2xy) )3 = (2)3 • (2x-y)3

Based on the lengths of the segments in the ellipse below, how long is the major axis of the ellipse? Show your work.
Check the picture below.
the distances d1 and d2 are for this ellipse 7 and 3 respectively, keeping in mind that their sum is always the same, namely d1 + d2 is always the same 10 no matter where on the ellipse you move the point, notice in the picture, if we move d1 to the extent that lies flat right on top of d2, we have the length of d1 in purple, plus the length of d2, which we later colored in darkyellow, if we move d2 to the right-hand-side or the tail of d1, we'd end up with the ellipse's major axis, which is oddly enough, d1 + d2.

2(5x + 3x2 -4) - (6x - 9)
Answer: X=3
Step-by-step explanation:
and the answer to the problem is 4x+13
Answer: 4x+13
Solution Steps
2(5x+3×2−4)−(6x−9)
Multiply 3 and 2 to get 6.
2(5x+6−4)−(6x−9)
Subtract 4 from 6 to get 2.
2(5x+2)−(6x−9)
Use the distributive property to multiply 2 by 5x+2.
10x+4−(6x−9)
To find the opposite of 6x−9, find the opposite of each term.
10x+4−6x−(−9)
The opposite of −9 is 9.
10x+4−6x+9
Combine 10x and −6x to get 4x.
4x+4+9
Add 4 and 9 to get 13.

A triangle has sides with lengths of 6 feet, 16 feet, and 17 feet. Is it a right triangle?
Answer:
No.
Step-by-step explanation:
This is not a right triangle. Use the Pythagorean Theorem, [tex]a^{2} + b^{2}=c^{2} \\[/tex], but write it as [tex]c^{2}= a^{2}+b^{2}[/tex]. The hypotenuse would be 17 feet, so you can insert 17 as [tex]c^{2}[/tex]. [tex]a[/tex] and [tex]b[/tex] could be 6 or 16. It can be written either way. The simplified equation would be:
[tex]c^{2}=a^{2} +b^{2} \\17^{2} = 6^{2} + 16^{2} \\17^{2} = 36+ 256\\17^{2}= 292\\289\neq 292[/tex]
This isn't a right triangle.

Answer:
Negative
Step-by-step explanation:
The slope is negative because as the x values increase, the y values decrease. If the line was going upward as the x values increase, it would be positive. If the line would be straight accross, it would be zero because the x values increase and the y values decrease.

What is the inverse of the conditional statement?
If a polygon has five angles, then it is a pentagon.
If a polygon is a pentagon, then it has five angles.
If a polygon is not a pentagon, then it does not have five angles.
If a polygon does not have five angles, then it is not a pentagon.
If a polygon has five angles, then it is not a pentagon.
(A.) If a polygon is a pentagon, then it has five angles.
The inverse of the conditional statement "If a polygon has five angles, then it is a pentagon" is "If a polygon does not have five angles, then it is not a pentagon."
Option C is the correct answer.
What is a pentagon?A pentagon is a polygon that has five sides and five angles.
The sides and angles of a pentagon are not all equal unless it is a regular pentagon.
A regular pentagon has five equal sides and five equal angles.
We have,
The inverse of a conditional statement is formed by negating both the hypothesis and the conclusion.
In this case, we negate the statement "a polygon has five angles" to "a polygon does not have five angles," and negate the statement "it is a pentagon" to "it is not a pentagon."
Thus,
The inverse of the conditional statement "If a polygon has five angles, then it is a pentagon" is "If a polygon does not have five angles, then it is not a pentagon."

Keisha's fish tank has 13 liters of water in it. She plans to add 4 liters per minute until the tank has at least 41 liters. What are the possible numbers of minutes Keisha could add water? Use t for the number of minutes. Write your answer as an inequality solved for t.
Answer:
7≥t
Step-by-step explanation:
The tank already has 13litres of water in it.
Keisha plans on increasing the quantity of the water to 41 litres. Hence,
41 litres - 13litres = 28litres
The above implies that she needed 28litres to be added to the fish tank.
She adds 4 litres per minute
Now, the question can now be reframed as how many minutes will be needed to add 28litre.
Considering to proportion method
4litres = 1 minute
28litres = t minutes
4litres × t minutes = 28litres
t = 28/4
t = 7 minutes
Hence, at least 7 minutes will be needed to increase the quantity of the tank water from 13litres to 41litres
But since we are to write the answer in an inequality form.
41≥ 13+4t
Solve for t
41≥13+4t
41-13≥4t
28≥4t
Divide both sides by 4
28/4≥4t/4
7≥t

A cell phone plan charges a base fee of $65 and an overage charge of $30 per gigabyte of data that exceed 2 gigabytes. If C represents the cost and G represents the total amount of gigabytes of data. What equation could represents this plan when more than 2 gigabytes are used
Answer:C =$65 + $30G
Step-by-step explanation:
Given that :
Base fee charge = $65
Overage charge = $30 / per gigabyte for data that exceeds 2 gigabyte
C = cost ; G = total amount of gigabyte
Equation to represent plan; if more than 2 gigabyte are used :
Cost (C) = Base charge + (average charge * amount of gigabyte)
C = $65 + ($30 * G)
C =$65 + $30G
