The elimination method was used to solve the following system of equations:

x2 + y2 = 9
Which of the following is the correct y-coordinate of the solution? (5 points)

Answer:
(c) 3
Step-by-step explanation:
You want the y-value of the solution to the equations ...
x² -y = -3x² +y² = 9EliminationWe are interested in the value of y, so it can be useful to eliminate x from the equation(s). The x² term appears in both, so it is convenient to subtract the first equation from the second.
(x² +y²) -(x² -y) = (9) -(-3)
y² +y = 12
y² +y -12 = 0 . . . . . . subtract 12
(y +4)(y -3) = 0 . . . . . factor
y = -4 or +3 . . . . . . . . values that make the factors zero
DomainSolving the first equation for y, we find ...
x² +3 = y . . . . . . . add y+3
We know that x² cannot be negative, so this tells us the values of y will be ...
y ≥ 3
Of the two solutions we found above, the value -4 is extraneous (not in the domain of y).

What is an equation?An equation is an expression that shows the relationship between numbers and variables using mathematical operators like addition, subtraction, multiplication and division. Equations can be linear, quadratic.
From the triangle:
∠OLM + ∠MLN = 180° (sum of angles in a straight line)
125 + ∠MLN = 180°
∠MLN = 55°
Also:
∠MLN + ∠MNL + ∠LMN = 180 (sum of angle in a triangle)
substituting:
55 + (2x - 10) + 65 = 180
2x + 110 = 180
2x = 70
x = 35°
∠LMN = 2x - 10 = 2(35) - 10 = 60°

At the same rate, how many miles would he drive in 13 hours?
Answer:871
Step-by-step explanation:If he drove 603 miles in 9 hours, he drove 67 miles per hour. So in 13 hours he will drive 67x13, which is 871.
Answer:

The height of flagpole a is 4.4 m.
What is the height of flagpole c?
In linear equation, 60m is the height of flagpole c .
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
Height/ Shadow
Shadow of the pole = 12 m
Height of the pole = x m
Tim's shadow = Height of the pole - Tim's distance
12 m - 10 m = 2 m
Tim's height = 2 m
Hence:
x/12 = 2/10
Cross Multiply
2x = 12 × 10
x = 120/2
x = 60 m
Approximately = 60m
Hence, the height of the flagpole = 60m

The items a to e that follow show the number of sides of a regular polygon. For each item, find the sum and the individual value of the interior angles.
a) 15 sides
b) 20 sides
c) 3 sides
d) 4 sides
e) 100 sides
For the polygon the individual value of the interior angles.
a) 15 sides is 145°
b) 20 sides is 108°
c) 3 sides is 60°
d) 4 sides is 90°
e) 100 sides is 18°
A regular polygon is one where all sides are the same length and all interior angles are the same. The number of sides of a regular polygon can affect the value of its interior angles.
a) 15 sides: The sum of the interior angles of a regular polygon with 15 sides is equal to 2180 degrees. To find the individual value of each angle, divide the sum by the number of sides. In this case,
=> 2180 / 15 = 145 degrees per angle.
b) 20 sides: The sum of the interior angles of a regular polygon with 20 sides is equal to 2160 degrees. To find the individual value of each angle, divide the sum by the number of sides. In this case,
=> 2160 / 20 = 108 degrees per angle.
c) 3 sides: The sum of the interior angles of a regular polygon with 3 sides is equal to 180 degrees. To find the individual value of each angle, divide the sum by the number of sides. In this case,
=> 180 / 3 = 60 degrees per angle.
d) 4 sides: The sum of the interior angles of a regular polygon with 4 sides is equal to 360 degrees. To find the individual value of each angle, divide the sum by the number of sides. In this case,
=> 360 / 4 = 90 degrees per angle.
e) 100 sides: The sum of the interior angles of a regular polygon with 100 sides is equal to 1800 degrees. To find the individual value of each angle, divide the sum by the number of sides. In this case,
=> 1800 / 100 = 18 degrees per angle.

62 kilograms was found to be equal to approximately 136.7 pounds using conversion formula.
To convert kilograms to pounds, the following formula is used:
Pounds = Kilograms x 2.20462
Plugging in 62 kilograms, we get:
Pounds = 62 x 2.20462
Pounds ≈ 136.7
Therefore, 62 kilograms is approximately equal to 136.7 pounds.
The pound (symbol: lb) is defined as exactly 0.45359237 kilograms, or approximately 16 ounces. There are also different types of pounds, such as the avoirdupois pound (used for general purposes) and the troy pound (used for precious metals).
The kilogram (symbol: kg) is used to measure the mass of an object or substance. For example, it can be used to measure your own body weight, the weight of a bag of groceries, or the mass of a planet. The prefix "kilo-" means "one thousand", so a kilogram is equal to 1,000 grams.

Find the value of z
6cm 15cm and right angle in triangle
For the given right triangle, the value of z is approximately 16.155 cm.
To find the value of z in a right triangle with sides 6 cm and 15 cm, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (z) is equal to the sum of the squares of the lengths of the other two sides (6 cm and 15 cm).
So we can write the equation:
z^2 = 6^2 + 15^2
Simplifying the equation:
z^2 = 36 + 225
Adding the numbers on the right side of the equation:
z^2 = 261
Taking the square root of both sides of the equation:
z = √261
Approximating the square root:
z ≈ 16.155
Therefore, the value of z is approximately 16.155 cm.
Note: The question is incomplete. The complete question probably is: Find the value of z (hypotenuse) if the other dimensions are 6cm, 15cm and right angle in triangle.

Suppose a car moving in straight line steadly increases it's speed each seconds first from 35 to 45km/h then 40 to 45 km/h then from 45 to 50km/h, What is the acceleration?
The acceleration of the car is not constant but is increasing steadily, starting at 10 km/h, decreasing to 5 km/h, and then remaining constant at 5 km/h.
To find the acceleration of the car, we need to use the formula:
acceleration = (final velocity - initial velocity) / time
Let's calculate the acceleration for each interval of time:
For the first interval, the initial velocity is 35 km/h and the final velocity is 45 km/h. The question says the speed increases each second.
Therefore, the acceleration is:
acceleration = (45 - 35) / 1 = 10 km/h
For the second interval, the initial velocity is 40 km/h and the final velocity is 45 km/h. Again, the acceleration is:
acceleration = (45 - 40) / 1 = 5 km/h
For the third interval, the initial velocity is 45 km/h and the final velocity is 50 km/h. The acceleration is:
acceleration = (50 - 45) / 1 = 5 km/h

Which of the following is the appropriate measure of variability for the data, and what is its value?
The IQR is the best measure of variability, and it equals 17.
The range is the best measure of variability, and it equals 4.
The IQR is the best measure of variability, and it equals 4.
The range is the best measure of variability, and it equals 17.
The correct option is C. The IQR is the best measure of variability, and it equals 4.
What is IQR (interquartile range)?The IQR (interquartile range), a measure of variability that depicts the range of the middle 50% of the data, is used in box plots. It is determined as the gap between the first and third quartiles (Q1 and Q3) (Q1). Since the box in this instance spans the numbers 17 to 21 on the number line, Q1 equals 17 and Q3 equals 21. IQR = Q3 - Q1 = 21 - 17 = 4 as a result.
The difference between the dataset's maximum and minimum values is represented by the range, another measure of variability. As a result of its sensitivity to extreme values, it is less reliable than the IQR. Although the range in this instance is equal to 27 - 10 = 17, it could not correctly reflect the variety of the data.
Therefore, the IQR is the most appropriate measure of variability for this data, and its value is 4.
