Answer: [tex]m - 5.25 = 4.75[/tex]

Step-by-step explanation:

We know Austin and his family go to the Carver Country Fair each year.

We also know Austin spends $5.25 trying to win a giant snake plushie.

He won the plushie, so we deduct $5.25. Our current equation is [tex]m - 5.25[/tex].

After spending $5.25 on a plushie, Austin still has 4.75.

We will now have our equation as [tex]m - 5.25 = 4.75[/tex]

The answer is Option B.

Answer:

[tex]\Large \boxed{\sf m-5.25=4.75}[/tex]

Step-by-step explanation:

Money received from Austin's dad - Money spent in Ring Toss = Money left after win at Ring Toss

Let 'Money received from Austin's dad'  be m

If -xy – 5+ y^2+ x^2= 0 and it is known that dy/dx= y-2x/-x+2y, find all
coordinate points on the curve where x = -1 and the line tangent to the
curve is horizontal, or state that no such points exist.

Answers

Answer:

There is no point of the form (-1, y) on the curve where the tangent is horizontal

Step-by-step explanation:

Notice that when x = - 1. then dy/dx becomes:

dy/dx= (y+2) / (2y+1)

therefore, to request that the tangent is horizontal we ask for the y values that make dy/dx equal to ZERO:

0 = ( y + 2) / (2 y + 1)

And we obtain y = -2 as the answer.

But if we try the point (-1, -2) in the original equation, we find that it DOESN'T belong to the curve because it doesn't satisfy the equation as shown below:

(-1)^2 + (-2)^2 - (-1)*(-2) - 5 = 1 + 4 + 2 - 5 = 2  (instead of zero)

Then, we conclude that there is no horizontal tangent to the curve for x = -1.

Assuming that the heights of college women are normally distributed with mean 65 inches and standard deviation 3.5 inches, what percentage of women are shorter than 68.5 inches

Answers

Answer: the percentage of women that are shorter than 68.5 inches is 84.1%

Step-by-step explanation:

Given that;

mean μ = 65

standard deviation σ = 3.5

percentage of women are shorter than 68.5 inches = ?

P( x < 68.5 ) = P(( x-μ)/σ)

we substitute

⇒ ( 68.5-65)/3.5)

⇒ P(z < 1)

form standard normal table

P( x < 68.5 ) = P(z < 1) = 0.84134 ≈ 84.1%

Therefore, the percentage of women that are shorter than 68.5 inches is 84.1%

You have $50 and a $15 gift card to spend online. You purchase a pair of headphones for $34.99 and 8 songs for x dollars each. Use an algebraic expression to find the amount you have left when each song costs $1.10.

Answers

Answer:

50 + 15 -34.99 - 8x

65 - 34.99 - 8(1.10)

30.01 - 8.8

$21.21

Step-by-step explanation:

The amount you have left when each song costs $1.10 is $21.21.

What is expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.

Given:

You have $50 and a $15 gift card to spend online.

Cost of each sing  = $1.10

You purchase a pair of headphones for $34.99 and 8 songs for x dollars each,

Calculate the total amount as shown below,

Total cost = cost of headphones + cost of each song × number of songs

Total cost = 34.99 + 1.10 × 8

Total cost = 34.99 + 8.8

Total cost = $43.79

Calculate the remaining cost as shown below,

Remaining cost  = $50 + $15 - total cost

Remaining cost  = $65 - $43.79

Remaining cost  = $21.21

Therefore, the amount you have left when each song costs $1.10 is $21.21.

How to determine the solution to the system?

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

x = 2y + 3

y = -3x - 4

Considering the first equation

x = 2y + 3

Considering the second equation

y = -3x - 4

Substitute the first equation in the second equation

y = -3(2y + 3) - 4

Hence, substituting the equation x = 2y + 3 into the equation y=-3x - 4 will produce the equation y = -3(2y + 3) - 4
