If 3x – y = 5 and 2x + y = 15, evaluate x^2 + 2y
Answers
If 3x – y = 5 and 2x + y = 15 then evaluation of x^2 + 2y is equal to 72.
What is evaluation ?
Finding the value of an algebraic expression when a given number is used to replace a variable is known as evaluating the expression. When evaluating an expression, we change the variable in the expression to the given number and then use the order of operations to simplify the expression.
3x-y=5 and 2x+y= 15
Add the two equations together to eliminate y
3x-y=5
2x+y= 15
---------------------
5x = 20
Divide by 5
5x/5 = 20/5
x = 4
Now we can find y
2x+y = 15
2(4) +y = 15
8+y =15
Subtract 8 from each side
8+y-8 = 15-8
y =7

Please help, this is geometry and I need to find the measure of the missing angle
Answers
The measure of missing angle is 145°.
Define linear pair theorem.When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°. The linear pair postulate or linear pair theorem in mathematics states the same thing mathematically. The sum of the measurements of two angles that make up a linear pair is 180°.
Given
Missing angle = x°
Opposite angle = 100°
Exterior angle = 35°
x and exterior angle are linear pair
Sum of linear pair is 180
x + 35 = 180
x = 180 - 35
x = 145

The Principal when calculated quarterly will give a sum of 2900 + (2.525)^4t at a rate of 6.1% interest
What is Compound Interest?
Compound interest is usually referred to as "interest on interest." Compound interest can work in your favour as your assets increase over time, but it can also work against you if you're paying off debt, such as credit cards. A calculator can assist in estimating how much money compound interest will generate over time.
Given that the Principal amount is $2900
and the Rate of Interest is 6.1%
Since, the interest is calculated quarterly
Amount = Principal * (1 + Rate/4)^4*Time
Amount = 2900 + (1 + 6.1/4)^4t
Amount = 2900 + (10.1/4)^4t
Amount = 2900 + (2.525)^4t

Why were goods planned to become obsolete?
A. So that the company would become known for quality goods
B. So that people would keep buying new things
C. So that companies could protect their brand
D. So that people could save as much money as possible
Answers
Answer: B
Step-by-step explanation: B. So that people would keep buying new things
Goods are often planned to become obsolete in order to encourage people to continue buying new things. This can be done by intentionally designing products with a limited lifespan or by using materials that are prone to wear and tear. Companies may also release new versions of products or discontinue support for older models in order to encourage consumers to upgrade to the latest version. By making their products become obsolete, companies can create a sense of urgency for consumers to keep buying new things and maintain their sales.

10. The table represents the relationship between the base length and the height of some parallelograms, Both measurements are in inches. What is the relationship between the base length and height of these parallelograms?
Answers
The relation between base length and height is: f(x) = 48/x
What is parallelogram?
A parallelogram is a straightforward quadrilateral in Euclidean geometry that has two pairs of parallel sides. A parallelogram has opposite sides that are facing one another and opposite angles that are of equal size.
By the values given in the table, for base length and height of the parallelograms, you can notice that base length increases 1 units, so you have 1, 2, 3, 4, 5.
For height you can notice that while base length increase 1 unit, height decreases by a factor of 1/x, just as follow:
1 - 48
2 - 24
3 - 16
4 - 12
5 - 8
The relation between base length and height is:
f(x) = 48/x
where f(x) is the height and x is the base length. In fact, you have:
f(1) = 48/1 = 48
f(2) = 48/2 = 24
f(3) = 48/3 = 16
f(4) = 48/4 = 12
Hence, the relation between base length and height is: f(x) = 48/x.

If the distances form a geometric sequence, the total distance Mr. Meyering jumps if he completes infinitely many jumps is equal to 40 inches.
What is a geometric sequence?In Mathematics, a geometric sequence can be defined as a series of real and natural numbers that are calculated by multiplying the next number by the same number (common ratio) each time.
Mathematically, the sum of an infinite geometric sequence can be calculated by using this mathematical expression:
S = a₁/(1 - r)
Where:
S represents the sum of an infinite geometric sequence.r represents the common ratio or constant ratio.a is the first term of a geometric sequence.How to determine the total distance Mr. Meyering jumps?First of all, we would determine the common ratio between the distances he jumped as follows;
Common ratio, r = a₂/a₁
Common ratio, r = 10/20
Common ratio, r = 0.5.
For the total distance, we have;
S = a₁/(1 - r)
S = 20/(1 - 0.5)
S = 20/0.5

Answer:
Lyric ran faster.
Step-by-step explanation:
When you plot y = 5x, you can trace a certain point to see which value is higher. When I plotted y = 5x and chose the point when x = 8, y = 40 for Kira, and for Lyric, at x = 8, y = 80. Since the y coordinate (distance) is higher, Lyric ran faster.
Lyric ran faster than Kira, since they were travelling a longer distance when comparing to Kira in the same period of time.
Step-by-step explanation:You may use the following logic to analyze this situation. Theoretically, the faster runner will have traveled a longer distance at any given point in time different than 0 when comparing to the other runner. Therefore, let's randomly pick a point in time to see who had traveled the longer distance.
The time we'll evaluate will be 4 seconds.
1. Evaluating the function to find Kira's traveled distance at 4 seconds.
For this, simply substitute the "x" by the number "4" in the given equation for Kira:
[tex]y=5(4)\\ \\y=20[/tex]
Conclusion: Kira had traveled a total distance of 20 yards, 4 seconds after starting the race.
2. Evaluating the function to find Lyric's traveled distance at 4 seconds.
To evaluate the graph, we'll have to draw a line where x=4 sits and then find the value of "y" the function returns. Check the attached images in order to see this process.
Conclusion: Lyric had traveled a total distance of 40 yards, 4 seconds after starting the race.
3. General conclusion.
After 4 seconds Kira traveled 20 yards;
After 4 seconds Lyric traveled 40 yards.
Conclusion: Lyric ran faster than Kira, since they were travelling a longer distance when comparing to Kira in the same period of time.
My past due bill is $585.00, and I just made payment arrangements for the next 3 months to keep my account from being suspended. My normal monthly bill is $50.00 per month. How much will I need to pay each month
Answers
He need to pay $245 per month .
How is the amount of interest you will pay calculated?
Subtract the number of payments you'll be making that year from the interest rate. You would divide 0.06 by 12 to get 0.005 if you had a monthly payment schedule and an interest rate of 6%. To calculate the amount of interest you will be required to pay that month, multiply that amount by the outstanding loan balance.Past due bill = $585
Now just made payment arrangements for the next 3 months to keep my account from being suspended
So, Payment each month of past bill = 585/3 = 195
His normal monthly bill is $50.00 per month.
So, I need to pay per month = $50+$195

The amount that Casey invested in the savings account is $10,000 and the amount Casey invested in the certificate of deposit is $60,000.
How much was invested in the savings account and the certificate of deposit?0.01c - 0.02s = $800 equation 1
c + s = $70,000 equation 2
Where:
c = amount invested in the certificate of deposit s = amount invested in the savings accountMultiply equation 2 by 0.01:
0.01c + 0.01s = 700 equation 3
Subtract equation 3 from equation 1:
0.01s = 100
Divide both sides of the equation by 0.01:
s = 100 / 0.01
s = 10,000

We know that,
We have to divide the equations,

Now we can divide the 36y by 12 y² we get 3/y
3(y²-1)/ y(y²- 2y+1)
We can write the y²-1 as (y-1)(y+1) and by formula y²-2y+1 as (y-1)²
3(y-1) (y+1)/ y (y-1)²
