Answer:

  (c)  3

Step-by-step explanation:

You want the y-value of the solution to the equations ...

We 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

Solving 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).

The y-coordinate of the solution is 3, choice C.

__

Additional comment

The solution is the point of intersection of the two curves shown in the attachment. The y-coordinate of that point is 3.

<95141404393>

The solution to the inequality is a coordinate of (-1.8, 0.6)

From the question, we have the following parameters that can be used in our computation:

y> -2x - 3

Y <4/3x +3

Next, we make a plot of the system to determine the solution

The shaded area in the plot represent the solution to the inequality

In this case, the shaded area has a coordinate of (-1.8, 0.6)

Hence, the solution is (-1.8, 0.6)

Answer:

81

Step-by-step explanation:

The correct option is C. The IQR is the best measure of variability, and it equals 4.

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.

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

Expression for actual length and actual width of the concrete patio are

30x inches and 30y inches respectively.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

For example, if we have a rectangle of sides 2 cm and 4 cm, we can enlarge it by multiplying each side by a number, say 2.

Given,

A blueprint of a concrete patio has a scale of 2 inches=5 feet.

2 inches = 60 inches

scale factor = 60/2 = 30

Let length of the patio on the blue print is x inches

width of the patio on the blue print is y inches

then actual length of the 30x inches

actual width of the patio = 30y inches

Hence, 30x inches is actual length and 30y inches is actual width of the concrete patio.

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.

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.

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
