What is a difference of squares that has a factor of x 8? x2−4 x2−16 x2−64 x2−256
Answer:
(c) x² -64
Step-by-step explanation:
The factoring of the difference of squares is one of the special forms we use in the study of polynomials. It tells you ...
a² -b² = (a +b)(a -b)
__
You have a factor (x +8), so a=x, b=8, and the "expanded" form is ...
a² -b² = x² -8² = x² -64
Answer:
x^2-64

Erica sells magazine subscriptions and makes a flat rate of $5.35 for each subscription she sells. if erica made $42.80 on monday, $64.20 on tuesday and $74.90 on wednesday, how many subscriptions did she sell in the three days? a. 32 b. 33 c. 34 d. 35 please select the best answer from the choices provided a b c d
Answer:
c. 34
Step-by-step explanation:
1) Add all the given prices on each day.
= 42.80 + 64.20 + 74.90
= 181.90
2) Set up an equation since we do not know how many magazine subscriptions she sold, but we know how much money she made.
Let x = number of magazine subscriptions sold
5.35x = 181.90
x = [tex]\frac{181.90}{5.35}[/tex]

Answer number 6 pleaseeeee
Answer:
20 peopleStep-by-step explanation:
25% = 1/4 of 100
100 represents 200 people here, that means that if 25 = 1/4 to 100, then it is 1/8 to 200. 25x8=200
If 25% = 50, since 50x4=200 and 1/4 = 25% of 100%.
50... ok......
50 = 25%
Now, because there are 5 parts in 25, let's divide 5 by 50, that is 10. That means that 5 = 10 in that 50. 5% = 10 people
So, if 25-15=10
and then 5% = 10 people
5%+5%=10
10+10=20
That means, that 20 people more liked the movie than disliked it.
What is an equation of the line that passes through the points (4, -2) and (2, 3)?
Step-by-step explanation:
For this problem, you'll need two formulas:
Slope: y1 - y2/x1 - x2
Point Slope: y - y1 = m(x - x1)
First thing you need to use is the slope formula.
Plugging in your coordinates gives you:
[tex]\frac{-2-3}{4-2}[/tex] = [tex]\frac{-5}{-2}[/tex]
You can simplify this by getting rid of the negatives since two negatives make a positive.
Now to use the point slope formula.
For this formula, the slope we just found, [tex]\frac{5}{2}[/tex], replaces the m, and for the x1 and y1, you use one of the original points(either (4,-2) or (2,3)).
I'll be using the point (2,3). Now plug everything in:
[tex]y-3=\frac{5}{2} (x-2)[/tex]
First thing you should do is distribute the [tex]\frac{5}{2}[/tex]:
[tex]y-3=\frac{5}{2} x-5[/tex]
Next thing to do is get the y by itself by adding 3 to both sides, which gives you your answer of:
[tex]y=\frac{5}{2} x-2[/tex]

Surah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 13 people took the trip. She was able to purchase coach tickets for $240 and first
class tickets for $1180. She used her total budget for airfare for the trip, which was $11,580. How many first class tickets did the buy? How many coach tickets did she buy?
Question 1.number of first class tickets bought -
Answer:
781.54
Step-by-step explanation:
240+1180= 1420
11580-1420 = 10160
10160÷13 ~=~ 781.54
PLACE as brainliest
Answer:
9 first class tickets
4 coach tickets
Step-by-step explanation:
Let x = number of first class tickets bought
Let y = number of coach tickets bought
Given:
A total of 13 people took the trip⇒ x + y = 13
Given:
Total cost of first class tickets = $1180Total cost of coach tickets = $240 Total budget = $11,580⇒ 1180x + 240y = 11580
Rewrite first equation to make y the subject:
⇒ y = 13 - x
Substitute this into the second equation and solve for x:
⇒ 240(13 - x) + 1180x = 11580
⇒ 3120 - 240x + 1180x = 11580
⇒ 940x = 8460
⇒ x = 9
Therefore, 9 first class tickets were bought.
To find the number of coach tickets bought, simply substitute the found value of x into equation 1 and solve for y:
⇒ 9 + y = 13
⇒ y = 4
Therefore, 4 coach tickets were bought.

Reflection over the y-axis.
Step-by-step explanation:
All the x values will change sign so its over the yaxis
Answer:
a. The graph will be reflected over the y-axis
Step-by-step explanation:
When a function is reflected over the y-axis, the x-coordinates are divded by -1, and then the new points will become reflections of the y-axis. Because x was changed to -x in this problem, we know that the graph was relfected across the y-axis.

Which products result in a difference of squares? select three options. (x minus y)(y minus x) (6 minus y)(6 minus y) (3 x z)(negative 3 x z) (y squared minus x y)(y squared x y) (64 y squared x squared)(negative x squared 64 y squared)
The three (3) products that resulted in a difference of squares are:
(3 + xz)(-3 + xz) (y² - xy)(y² + xy)(64y² + x²)(-x² + 64y²)How to determine the difference of squares?In Mathematics, the standard form for a difference of two (2) squares is given by a² - b² = (a + b)(a - b).
(3 + xz)(-3 + xz) = (3 + xz)(xz -3)
(3 + xz)(xz -3) = 3xz - 9 + x²z² - 3xz.
(3 + xz)(xz -3) = x²z² - 9
Therefore, x²z² - 9 ≡ a² - b²
(y² - xy)(y² + xy) = y⁴ + xy³ - xy³ - x²y²
(y² - xy)(y² + xy) = y⁴ - x²y²
Therefore, y⁴ - x²y² ≡ a² - b².
(64y² + x²)(-x² + 64y²) = (64y² + x²)(64y² - x²)
(64y² + x²)(-x² + 64y²) = 4096y⁴- 64y²x² + 64y²x² - x⁴
(64y² + x²)(-x² + 64y²) = 4096y⁴ - x⁴
Therefore, 4096y⁴ - x⁴ ≡ a² - b².
