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

Answers

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).

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?

Answers

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.

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

Answers

Answer:  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
