-2x – 1 = y
5y + 3x = 9
solve for x and y

Answers

Answer 1

Answer:

(-2,3)

Step-by-step explanation:

(-2,3) hope this helps

Answer 2

Answer:

Step-by-step explanation:

y=-2x-1

5y+3x=9, using y from above in this equation gives you

5(-2x-1)+3x=9

-10x-5+3x=9

-7x-5=9

-7x=14

x=-2, and since y=-2x-1

y=-2(-2)-1

y=4-1=3, so the solution is the point (-2,3)

x=-2 and y=3

Answers

There are 4 "3" cards in a deck of 52 cards, so there is a 4/52 = 1/13 probability of selecting a "3".

If A is an event, then P(A) + P(not A) = 1, so P(not A) = 1 - P(A)

The probability of not selecting a "3" = 1 - probability of selecting a "3" = 1 - 1/13 = 12/13

A drama class has a total of 39 students. The number of males is 9 more than the number of females. How many males and how many females are in the class?

Answers

Answer:

Step-by-step explanation:M+F=39

M+F=39

F=M-9

Substitute

M + M - 9 = 39

2M = 48

M=48/2

M=24

24+F=39

F=39-24=15

F=15, M=24

Answer:

15 females

24 males

Step-by-step explanation:

Given;

39 students total

9 more male student than female

1. Set up an equation

Call the number of female student "x"

Since there are 9 more male students, the number of male students is (x + 9),

Assuming those are the only genders in the class, the equation formed is;

females + males = total

x + x + 9 = 39

2. Solve,

Simplify and inverse operations;

x + x + 9 = 39

2x + 9 = 39

2x = 30

x = 15

15 females

24 males

Brian has 8 feet of canvas. He needs 1/4 foot to make a painting.
How many paintings can Brian make?

Answers

Answer:

32 paintings

Step-by-step explanation:

You have to divide 8 by [tex]\frac{1}{4}[/tex]

turn 8 into a fraction by putting a 1 under it, [tex]\frac{8}{1}[/tex], and flip the other fraction, [tex]\frac{4}{1}[/tex]

now, you multiply the fractions

[tex]\frac{8}{1}[/tex] ×[tex]\frac{4}{1}[/tex]= [tex]\frac{32}{1}[/tex], so you get 32 over one, which you can just simplify into 32

Brian can make 32 paintings.

Carmen is a professor at a local university. In collecting data on her Introduction to Business course for a year, she wants to calculate the z-score for a student who scores a 83 on the final exam. The mean and the standard deviation scores on the exam are 72 and 5, respectively. Calculate the z-score.

Answers

Answer:

[tex]\boxed {\boxed {\sf z=2.2}}[/tex]

Step-by-step explanation:

The z-score tells us how many standard deviations a value is away from the mean.

The formula is:

[tex]z=\frac{x- \overline{x}}{s}[/tex]

where x is the value, [tex]\overline {x}[/tex] is the mean, and s is the standard deviation.

We want to find the z-score for the score of an 83, the mean is 72, and the standard deviation is 5.

[tex]x=83 \\\overline {x}= 72 \\s=5[/tex]

Substitute the values into the formula.

[tex]z=\frac{83-72}{5}[/tex]

Solve the numerator.

[tex]z=\frac{11}{5}[/tex]

Divide.

[tex]z=2.2[/tex]

The z-score is 2.2, which means the score of 83 is 2.2 standard deviations above the mean.

Jamal has $15.00 to spend at the concession stand. He buys nachos for $7.50, and he wants to purchase some sour straws for $1.50 each. How many sour straws can Jamal purchase with the money that he has?(solve with inequality/solve for x)

Answers

Answer:

x = 5

$15.00 is the total amount of money Jamal has right? To find the remaining amount of money Jamal has subtract 15 - 7.5 (price of nachos) = 7.5 (remaining amount of money Jamal has.) Now for part 2, since the sour straws are $1.50 each you just have to multiply X to get close as close to the remaining amount of money as possible.

1.50× 5 (amount of sour straws) is equal to 7.50 (price of 5 sour straws).

To check your answer let's add the price of nachos (7.50) and 5 sour straws (7.50) which is 15.00 the total amount Jamal brought with him.

For the function k(x) =Negative StartFraction 1 Over 16 EndFraction x – 8, what is the inverse function k–1(x)?

Answers

Answer:

Step-by-step explanation: it’s D on edge

The inverse function is,

⇒ k⁻¹ (x) = -16 (x + 8)

What is Inverse function?

The inverse function returns the  original value for which a function gave the outputs.

Given that;

The function is,

k (x) = -1/16 x - 8

Now, Find the inverse function as;

k (x) = -1/16 x - 8

Substitute k (x) = y,

y = -1/16 x - 8

Find the value of x in terms of y,

y = -1/16 x - 8

y + 8 = -1/16 x

16 ( y + 8 ) = -x

x = -16 ( y + 8 )

Replace x and y,

y = -16 ( x + 8 )

Thus, The inverse function is,

⇒ k⁻¹ (x) = -16 (x + 8)

x=20 hope this helps :)

The value of X is 20.

To find this answer, you must first find the least common denominator of both fractions. In this case, the LCD is 36.

Next, you multiply the left side by 4/4. The fraction 4/4 is simply found by dividing the right side denominator (36) by the left side denominator (9). 9 goes into 36 4 times.

5/9 * 4/4 = 20/36.

Thus meaning X = 20. I hope this helps!
