Find the value of y for which a the values of 5y+3 and 36–y are equal
plzzzz
Answer:
11/2
Step-by-step explanation:
5y+3=36-y
1) Subtract 3 from both sides:
5y=33-y
2) Add y to both sides:
6y=33
3) divide both sides by 6:
y=33/6
4) Simplify the fraction:
11/2
The value of y for which the values of 5y+3 and 36–y are equal = 11 / 2.
How to find the Value of the equation?Given:
5y+3 and 36-y
To find:
the value of y.
Step 1
Let the equation be
5y+3 = 36-y
Subtract 3 from both sides of the above equation
5y+3-3 = 36-y-3
Simplifying the equation, we get
5y = -y+33
Step 2
Adding y to both sides
5y+y = -y+33+y
Simplify
6y = 33
Divide both sides by 6, then we get
6y / 6 = 33 / 6
Simplify
y =11 / 2
Therefore, the correct answer is y = 11 / 2.

What is the value of 1 exponent 102? What is the value of any power of 1? Justify your answer.
The value of [tex]1^{102[/tex] is 1 because 1 multiply by itself results to 1.
What is Exponents and power?A number's exponent indicates how many times the number has been multiplied by itself.
: Since 2 is multiplied by itself 4 times, 2x 2 x 2x 2 can be expressed as [tex]2^4[/tex]. Here, 4 is referred to as the "exponent" or "power," while 2 is referred to as the "base."

Final answer:
The value of 1 raised to any power, including 1 exponent 102, is 1. When you multiply 1 by itself any number of times, the result is always 1 because the identity property of multiplication states that any number multiplied by 1 remains unchanged.
Explanation:
The value of 1 exponent 102, or $1^{102}$, is 1. In fact, the value of any power of 1 is always 1. To understand this, let's think of the exponent as how many instances of a number are multiplied together. When you multiply 1 by itself any number of times, the result remains 1 because multiplying by 1 does not change the value of the original number. Thus, 1 to any power, whether it's 1 or 102, will still give us 1.
Using these principles, let's address another problem without entering scientific notation into your calculator. To evaluate $(4.506 \times 10^4) \times (1.003 \times 10^2)$, we can multiply the coefficients (4.506 \times 1.003) and then add the exponents of 10 (4 + 2), since when powers of 10 are multiplied together, the exponents are added. The result is approximately 4.514518 \times 10^6.
The travel time for a plane traveling at a rate of r kilometers per hour for 900 kilometers
The travel time for a plane traveling at a rate of r kilometers per hour for 900 kilometers can be calculated using the formula: Time = Distance / Speed. So, the travel time for the plane would be 900 / r hours.
Explanation:The travel time for a plane traveling at a rate of r kilometers per hour for 900 kilometers can be calculated using the formula:

Please need help on this please
Answer:
C
Step-by-step explanation:
Given
x² - 10x + 24 = 0
Consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 4 and - 6, since
- 4 × - 6 = + 24 and - 4 - 10 = - 10, hence
(x - 4)(x - 6) = 0 ← in factored form → C
Answer:
○ C (x - 4)(x - 6)
Step-by-step explanation:
According to the Quadratic Equation of x² - 10x + 24, you have to find two numbers that when added up to 10, they also multiply up to 24, and those would be 4 and 6, and determining which signs each quantities get would depend on the sign in the midst of the equation [-], so in this case, both 6 and 4 get the negative symbol because -6 - 4 gives you -10, which is what you see in the midst of the equation. So with that, you have your answer.

Lia claims that a reflection over the y-axis will always carry a circle drawn on the coordinate plane to a circle with the same center and the same radius. Which statement best describes Lia's claim?
A
Lia is correct as a reflected circle will always have the same center and always have the same radius as the original circle.
B
Lia is incorrect as a reflected circle will not always have the same radius and will not always have the same center as the original circle.
C
Lia is correct in stating that the reflected circle will always have the same radius, but is incorrect in stating that the reflected circle will always have the same center.
D
Lia is incorrect in stating that the reflected circle will always have the same radius, but is correct in stating that the reflected circle will always have the same center.
Answer: YOUR ANSWER WOULD BE B
Step-by-step explanation: Your answer would be B because when you reflect something on the y-axis it always goes one cube or dashed line forward so it will not have the same radius nor the circle hope this helps you alot
Answer:
C. Lia is correct in stating that the reflected circle will always have the same radius, but is incorrect in stating that the reflected circle will always have the same center.Step-by-step explanation:
Lia's claim is not correct, because when we reflect a figure, its coordinates variate. In this case, Lisa is trying to reflect a circle over the y-axis, which will change y-axis coordinates. The center of the circle is gonna change its y-axis coordinate, for example, if the center is [tex]C(2;3)[/tex], its reflection will be [tex]C(2;-3)[/tex]
Therefore, the center of the circle will not remain the same. However, the radius will be the same, because changing y-axis coordinates don't affect the distance between the center and the circumference of the circle.
So, the correct answer is option C.

Gary and Ann have a joint checking account. Their balance at the beginning of October was $9145.87.
During the month they made deposits totaling $2783.71, wrote checks for $4871.90, paid a maintenance
fee of $12, and earned $11.15 in interest on the account. What was the balance at the end of the month?
Answer:
The balance at the end of the month was $7,056.83
Step-by-step explanation:
we know that
The balance at the end of the month is equal to the balance at the beginning of the month plus deposits and interest minus checks and maintenance fee
so
9,145.87+(2,783.71+11.15)-(4,871.90+12)
9,145.87+(2,794.86)-(4,883.90)=$7,056.83
Answer:
The balance was $ 7,056.83
Step-by-step explanation:
Given,
The original balance in beginning of the month = $9145.87,
The amount of deposit = $2783.71,
So, new balance after depositing = $9145.87 + $2783.71 = $ 11929.58,
Check amount = $4871.90,
After clearing check, the new balance = $ 11929.58 - $ 4871.90 = $ 7057.68,
Also, after charging $ 12 fees, new balance = $ 7057.68 - $ 12 = $ 7045.68,
Finally getting $ 11.15 interest,
The final balance at the end of month = $ 7045.68 + $ 11 = $ 7,056.83
A house has increased in value by 34% since it was purchased the current value is 469,000 what is the value when it was purchased
The original purchase price of the house was approximately $350,000. This is determined by dividing the current value by 1.34, since the current value represents 134% of the original price. Housing prices generally rise over time, but there can be periods of significant drop.
Explanation:To find the original purchase price of the house before the increase, we need to understand that the current value represents 100% + 34% = 134% of the original price. Therefore, we can set up the equation 469,000 = 1.34*X, where X is the original value. We can solve for X by dividing both sides by 1.34, which gives X = 469,000 / 1.34, approximately $350,000. Therefore, the house was purchased for about $350,000.
It is important to note that housing prices can fluctuate over time. For example, housing prices have usually risen steadily over time but there are periods where they have dropped significantly, like the housing bust between 2008 and 2009. However, housing is typically considered a safe financial investment over the long term.

How do you calculate your overall gpa from your cumulative gpa?
Answer:
Your grade point average (GPA) is calculated by dividing the total amount of grade points earned by the total amount of credit hours attempted. Your grade point average may range from 0.0 to a 4.0. To get the example student's GPA, the total grade points are divided by the total credit hours attempted. To calculate your cumulative G.P.A., total the credit hours and then the grade points from all semesters. Divide the total grade points by the total credit hours.
Hope this helps.
To calculate your overall GPA from your cumulative GPA, multiply each grade by the number of credit hours, sum up all the grade points, and divide by the total number of credit hours.
Explanation:To calculate your overall GPA from your cumulative GPA, you will need to determine the total number of grade points earned and the total number of credit hours taken. To do this, multiply each grade received by the number of credit hours for that course. Then, sum up all the grade points and divide by the total number of credit hours. This will give you your overall GPA.
Here is an example:
Course A: Grade - B (3.0), Credit Hours - 3Course B: Grade - A (4.0), Credit Hours - 4Course C: Grade - C (2.0), Credit Hours - 2Total grade points: (3.0 x 3) + (4.0 x 4) + (2.0 x 2) = 9.0 + 16.0 + 4.0 = 29.0

So the slope would have been 8/0 but this is undefined.
So the slope is undefined.
Also notice the x's are the same and the y's are difference so this is a vertical line. There is only rise in a vertical line and no run. Recall, slope is rise/run. You cannot divide by 0 so this is why we say the slope is undefined when the x's are always the same no matter the y.

B. (3, 5)
C. (0, 2)
D. (-2, 1)

It might be wrong, but if i was to answer, this is what i would put.
Answer: Hello there!
your set is {(1,-2), (0,4), (2,-3)} where the pairs have the form (x,y)
You want to know with pair you need to add to this set in order to make it "not a function"
The priority rule for a function is the unicity; this means that each value of x has only one value of y associated; or:
if f(x) = y1 and f(x) = y2, then y1 = y2
(notice that a given value of y can be related to different values of x; for example the function f(x) = x^2 has the same y value for x and -x)
Then the problem is if we add the pair (0,2), of option C.
because we already have a pair with the value of x = 0, in the form of (0,4), and these two pairs would have a different value of y for the same value of x, then this set doesn't represent a function anymore.
Then the correct option is C
