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.

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.

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.

When a number is subtracted from 25, the difference is 8 less than twice
that number. What is the number?
Answers
Answer:
11
Step-by-step explanation:
first, we would set up an equation. since they say that a number is subtracted from 25, let x represent that number and say 25-x. on the other side of the equation, since it says the difference would be 8 less than twice that number, we would say 2x-8 because twice x would be 2x and we'd subtract 8 from that.
the equation would look like this:
25-x=2x-8
next, we would solve. first get the x to one side of the equation:
25=3x-8
then, get the 3x by itself:
33=3x
finally, solve for x by dividing both sides of the equation by 3:
11=x
x=11.
The number is 11.

What are linear equations?Linear equations are equations that have constant average rates of change, slope or gradient
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

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%
