Line AB is definited by the equation ax+by=c where a=0, b=1, and c=-2 graph line AB

Answer:

y = 23 , ∠ S = 135° , ∠ T = 45° are correct

Step-by-step explanation:

the opposite angles of a parallelogram are congruent , then

6x - 9 = 4x + 39 ( subtract 4x from both sides )

2x - 9 = 39 ( add 9 to both sides )

2x = 48 ( divide both sides by 2 )

x = 24 ≠ 15

and

3y - x = 2y - 1 , that is

3y - 24 = 2y - 1 ( subtract 2y from both sides )

y - 24 = - 1 ( add 24 to both sides )

y = 23 ← is correct

∠ R = 3y - x = 3(23) - 24 = 69 - 24 = 45°  ≠ 27°

∠ S = 6x - 9 = 6(24) - 9 = 144 - 9 = 135° ← is correct

∠ T = ∠ R = 45° ← is correct

∠ U = ∠ S = 135° ≠ 99°

Michael and Ashley bought same amount of turkey and ham.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Michael and Ashley each buy x pounds of turkey and y pounds of ham.

Michael purchased from store A.

Cost of turkey per pound at store A = $3

Cost of ham per pound at store A = $4

Michael spends $18 at store A.

3x + 4y = 18

Ashley purchased from store B.

Cost of turkey per pound at store B = $4.50

Cost of ham per pound at store B = $6

Ashley spends $27 at store B.

4.5x + 6y = 27

We get two linear equations,

3x + 4y = 18

4.5x + 6y = 27

Multiplying the first equation throughout with 4.5 and the second equation throughout with 3, we get,

13.5x + 18y = 81

13.5x + 18y = 81

Since both the equations coincide, Michael and Ashley bought same amount of Turkey and Ham.

Hence Michael and Ashley bought same amount of turkey and ham.

The probability that a randomly selected bird is a parakeet given that it is green is 54.1%.

The area of mathematics known as probability explores potential outcomes of events, along with the likelihoods and distributions of those occurrences.

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

Probability is a measure of the likelihood that an event will occur or the likelihood that something will happen. The likelihood that the coin will land with the heads side up after being tossed into the air is described using the word probability.

Let,

A be the  Parakee

B be the Green

To find the probability that a randomly selected bird is a parakeet given that it is green.

That means P(A|B)

The number of birds that are both parakeet and green is n(A∩B)=20

The number of birds that are green is n(B)=37

Hence, using the conditional probability formula P(A∣B) = [tex]\dfrac{n(A\bigcap B}{n(B)}[/tex]

P(A∣B) = [tex]\dfrac{n(A\bigcap B)}{n(B)}[/tex]

P(A∣B) = 20/37

P(A∣B) = 20/37 × 100%

P(A∣B) = 54.1%

Thus, the probability that a randomly selected bird is a parakeet given that it is green is 54.1%.

The Output Variable is Total cost represented by c(m).

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

Given:

A website charges $3 for each movie you download.

They also charge a one-time sign-up fee of $14.99.

So, the input variable will be m which shows the number of movies.

and, the output variable will be c which shows the total cost.

Then, the equation models the cost c(m), is c(m)=3m+14.99

Now, putting the values for m = 0, 1, 2, ....

c(0)= 4.99, c(1)= 17.99, c(2)= 20.99

Hence, the output variable is total cost.
