Answer:
-10 or -$10
Step-by-step explanation:
The 10 would be negative, due to taking away 10 instead of adding it.

What is the equation of a hyperbola with a = 5 and c = 15? Assume that the transverse axis is horizontal.
Answer:
[tex]\frac{x^2}{25} -\frac{y^2}{200} =1[/tex]
Step-by-step explanation:
Recall that the equation of hyperbola centered at the origin with transverse horizontal axis has the general form:
[tex]\frac{x^2}{a^2} -\frac{y^2}{b^2} =1\\and\,\,\,\, with\\c=\sqrt{a^2+b^2}[/tex]
since we know that a = 5 ,and c = 15,we can solve for b:
[tex]15=\sqrt{5^2+b^2} \\15^2=25+b^2\\b^2=200\\[/tex]
then the equation of the hyperbola becomes:
[tex]\frac{x^2}{5^2} -\frac{y^2}{200} =1\\\frac{x^2}{25} -\frac{y^2}{200} =1[/tex]
Two statements are missing reasons.What reason can be used to justify both statements 2 and 3?
2h + (6 + h) + 6 ∙ 2
Answer: 3h+18
Step-by-step explanation:
2h+6+h+12
add like terms (add all the the h’s) which equals 3h and add 6+12 which equals 18 so your answer is 3h+18

Two cards are randomly pulled out of a standard pack of 52 cards. What is the probability
that both are face cards?
A. 9/169
B. 12/221
C. 33/676
D. 11/221
========================================================
Work Shown:
For any given suit, there are 3 face cards: Jack, Queen, King.
There are 4 suits, leading to 4*3 = 12 face cards out of 52 total.
The probability of pulling out a face card is 12/52.
After that card is selected, we have 12-1 = 11 face cards left and 52-1 = 51 cards left overall. This is assuming a replacement is not made, or the card is not put back.
The probability of getting another face card, given the first selection was a face card, is 11/51.
Multiplying the two fractions gives:
P(2 face cards) = P(1st facecard)*P(2nd facecard given 1st facecard)
P(2 face cards) = (12/52)*(11/51)
P(2 face cards) = (12*11)/(52*51)
P(2 face cards) = (3*4*11)/(13*4*3*17)
P(2 face cards) = (11)/(13*17)
P(2 face cards) = 11/221
For Carl's birthday, his grandparents gave him a $50 gift card to a local movie theater. The theater charges $6 admission for each movie. How can Carl use an arithmetic sequence to determine the value left on his card after each movie he sees?
Answer:
50 - 6x = leftover value
Step-by-step explanation:
X is the amount of movies he has seen (pays $6 for each movie)
Carl can use the function → a(n) = 56 - 6n determine the value left on his card after each movie he sees.
We have Carl's grandparents who gave him a $50 gift card to a local movie theater. The theater charges $6 admission for each movie.
We have to check how can Carl use an arithmetic sequence to determine the value left on his card after each movie he sees.
What is an Arithmetic sequence?An arithmetic sequence is a sequence of numbers in which every term (except the first term) is obtained by adding a constant number to the previous term is called an arithmetic sequence.
According to the question, we have -
Amount in Gift card = $50
Charges for Admission to every new movie = $6
Therefore, we can create a arithmetic sequence with -
a = 50 and d = -6
Therefore -
a(n) = a + (n - 1)d
a(n) = 50 + (n - 1)(-6)
a(n) = 50 - 6n + 6
a(n) = 56 - 6n
where n denotes the number of movies he watch and a(n) is money remained after watching the movies.
Hence, Carl can use the function a(n) = 56 - 6n determine the value left on his card after each movie he sees.

What is the solution for 2X- 5=7
Answer:x = 6
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
Add 5 to both sides of the equation:
2x -5 = 7
2x -5 +5 =7 +5
Simplify:
2x=12
Divide both sides of the equation by the same term:
2x = 12
2x/2 = 12/2
Simplify again:
x=6
Answer:
x = 6
1) Write the equation parallel to the following equations that would go through (2,7):
a) Y = 3x - 2
b) Y = % x + 3
c) Y = x - 6
d) Y + 2x = 8
So 1 equation per letter
Note: Your option 'b' is somewhat ambiguous, so I am assuming you meant to write the equation y=2x+3 for the 'b' option.
Answer:
the equation y = 2x + 3 has slope m=2 and the y-intercept is 3, and also PASSES through the point (2, 7).
Step-by-step explanation:
An equation parallel to the given line equation will have the same slope.Given the point (2, 7) from which the equation passes through.
so checking all the equations in the options to check whether any equation passes through or not.
Checking the option 'a':
y = 3x - 2
Putting (2, 7)
7=3(2)-2
7=6-2
7=4
L.H.S is not equal to R.H.S
Therefore, the option 'a' is NOT correct.
So, the equation y = 3x - 2 will NOT PASS through the point (2, 7)
Checking the option 'b':
y = 2x + 3
Putting (2, 7)
7=2(2)+2
7=7
7=7
L.H.S is equal to R.H.S
Therefore, option 'b' is the CORRECT option.
So, the equation y = 2x + 3 will PASS through the point (2, 7)
Checking the option 'c':
y = x-6
Putting (2, 7)
7=2-6
7=-4
L.H.S is not equal to R.H.S
Therefore, the option 'c' is NOT correct.
So, the equation y = x-6 will NOT PASS through the point (2, 7)
Checking the option 'd':
y + 2x = 8
Putting (2, 7)
7+2(2)=8
7+4=8
11=8
L.H.S is not equal to R.H.S
Therefore, the option 'd' is NOT correct.
So, the equation y + 2x = 8 will NOT PASS through the point (2, 7)
Therefore, considering the above analysis, we conclude that:
Option 'b' is the CORRECT option.
So, the equation y = 2x + 3 will PASS through the point (2, 7).
also
The slope-intercept form of the equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
Therefore, the equation y = 2x + 3 has slope m=2 and the y-intercept is 3, and also PASSES through the point (2, 7).

Find the coordinates of point P that lies along the directed line segment AB in a 2:3 ratio given A (-2, 1), B (3, 4).
Answer:
[tex]P(x,y) = (0,\frac{11}{5})[/tex]
Step-by-step explanation:
Given
[tex]A = (-2,1)[/tex]
[tex]B = (3,4)[/tex]
[tex]m:n = 2:3[/tex]
Required
Determine the coordinates of P
The coordinate of a point when divided into ratio is:
[tex]P(x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]
Where
[tex](x_1,y_1) = (-2,1)[/tex]
[tex](x_2,y_2) = (3,4)[/tex]
[tex]m:n = 2:3[/tex]
This gives:
[tex]P(x,y) = (\frac{2 * 3 + 3 * -2}{2 + 3},\frac{2 * 4 + 3 * 1}{2 + 3})[/tex]
[tex]P(x,y) = (\frac{6 - 6}{5},\frac{8 + 3}{5})[/tex]
[tex]P(x,y) = (\frac{0}{5},\frac{11}{5})[/tex]
[tex]P(x,y) = (0,\frac{11}{5})[/tex]
