Answer:
the second one
Step-by-step explanation:
in order for it to be a function the x values CANNOT repeat.
in answer a the x value -6 repeats so that cannot be a function
in answer b none of the x values repeat so its probably this one but lets check the other ones just in case
in answer c the x value 8 repeats so it cannot be this one
in answer d the x value -2 repeats so it cant be this one \
b is the only one that does have repeating x values therefore it is the second one

Why is it important to understand how variables work, inequalities, and basic awareness of exponents before starting algebra?
Answer:
It is important because they are the basics of algebra. Almost every algebraic problem you will ever solve is based on these fundamental properties. In equations, we almost never know every part of it so we will need variables to substitute the unknown amount in an equation. Variables are used for basically every equation/problem in algebra. Inequalities are not as important as variables but are still really important. Inequalities are basically comparing numbers. And in algebra when they add variables into an inequality, the inequality will help lower the number of possible values of said variable. And exponents are just a basic operation in algebra. Just like learning addition and subtraction. It is like a quicker and less complicated way of multiplying numbers.

Marci purchased the rug shown. To the nearest hundredth, what area of floor space will the rug cover? (π = 3.14)
Answer:
63.59
Step-by-step explanation:
The area of floor space will the rug cover is 63.59 square feet.
The correct option is D.
What is a diameter?A straight line that runs through the sideways of a body or figure, particularly a circle or sphere, is called as a diameter of a circle or sphere.
Given:
A rug is circular.
And diameter = 9 feet.
So, the radius of the circle is = 4.5 feet.
The area of floor space will the rug cover,
= πr²
= 3.14 x 4.5 x 4.5
= 63.59 square feet.
Therefore, the area is 63.59 square feet.

Answer: The lateral area of a right pyramid can be calculated by multiplying half of the perimeter of the base by the slant height. This is summarized by the formula: LA 5 Ps. We can relate this formula to the square pyramid below and its net. The side length of the base of the pyramid is b, and the slant height is s.
-1 2/3 divided by (-2 1/5)
Answer:0.75757575757
Answer:
Fraction Form
25/33
Decimal Form
0.75
Step-by-step explanation:
First, convert the mixed fraction into an improper fraction, so it would look like:
-5/3 / (-11/5)
Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:
5/3 x 5/11
Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33

The current temperature is 48 degrees Fahrenheit it is expected to drop 1.5 degrees each hour. Determine in how many hours the temperature will be 36 degrees Fahrenheit.
The answer is that it would take 8 hours for the temperature to drop down to 36 degrees.
1.5x8=12
1x8=8 and 0.5x8=4
In 8 hours the temperature will be 36°F from 48°F.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, The current temperature is 48 degrees Fahrenheit it is expected to drop 1.5 degrees each hour.
Assuming the no. of hours to be x.
∴ 36 = 48 - 1.5x.
- 1.5x = - 12.
x = 8.

Hello there !
Can I have some help with this question? Thank you !
Answer:
About 6 hours.
Step-by-step explanation:
The cylinder has a diameter of 10 meters and a depth of 1.4 meters.
First, we can find the volume of the cylinder, given by the formula:
[tex]V=\pi r^2h[/tex]
Where r is the radius and h is the height (or depth, in this case).
Since our diameter is 10, our radius is 5.
Therefore, the volume of the cylinder will be (using 3.14 as π):
[tex]V=(3.14)(5)^2(1.4)=109.9\text{ meters} ^3[/tex]
Since water is pumped at a rate of 18 cubic meters per hour, it will take then:
[tex]109.9/18=6.10\overline{5}\approx 6\text{ hours}[/tex]
So, it will take about 6 hours for the water to completely fill the pool.
Solve the system of linear equations by elimination. 11x−20y=28 , 3x+4y=36
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The value of x is 8.
The value of y is 3.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 7 is an equation.
We have,
11x - 20y = 28 ____(1)
3x + 4y = 36 _____(2)
Now,
Multiply 5 on (2).
11x - 20y = 28
15x + 20y = 180
26x = 208
This means,
x = 208/26
x = 8
Now,
11x - 20y = 28
11 x 8 - 20y = 28
88 - 20y = 28
88 - 28 = 20y
y = 60/20
y = 3
Thus,
The value of x is 8.
The value of y is 3.

The function g(t) = -16t2 + vt + h represents the height of an object, g, in feet above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet.
A model rocket is launched off the ground at an initial velocity of 80 feet per second.
Write a function that can be used to describe the flight of the model rocket.
A. g(t) = -16t^2 + 80
B. g(t) = -16t^2 + 80t
C. g(t) = -16t^2 + t + 80

Find all sides of a right triangle whose perimeter is equal to 60 cm and its area is equal to 150 square cm
Answer:
15cm by 20cm by 25cm
Step-by-step explanation:
Let the sides of the right angle be x, y and h
x is the breadth
y is the height
h is the hypotenuse
Perimeter = x + y + h
x + y +h = 60
x+y = 60-h .... 1
If its area is equal to 150 square cm, then;
Area = 1/2 * base * height
Area = 1/2 *x * y
xy/2 = 150
xy = 300 ....2
According to pythagoras theorem;
x² + y² = h²
On expanding x² + y²
x² + y² = (x+y)² - 2xy
The equation becomes
(x+y)² - 2xy = h² ... 3
Substitute equation 1 and 2 into 3;
From 3;
(x+y)² - 2xy = h² ... 3
(60-h)² - 2(300) = h²
3600-120h + h² - 600 = h²
3600-120h - 600 = 0
-120h = 600-3600
-120h = -3000
h = 3000/120
h = 25cm
Recall that x+y+h = 60
x+y+25 = 60
x+y = 60 - 25
x+y = 35 ... 4
From equation 2;
xy = 300
x = 300/y ..... 5
Substitute 5 into 4;
300/y + y = 35
(300+y²)/y = 35
300+y² = 35y
y²-35y + 300 = 0
y²-20y-15y + 300 = 0
y(y-20)-15(y-20) = 0
y-20 = 0 and y - 15 =0
y = 20 and 15
since x+y = 35
x + 20 = 35
x = 35 - 20
x = 15
Hence the sides of the triangle are 15cm by 20cm by 25cm
