Explanation:
A relation is any set of (x,y) points usually with some rule tying them together. Though that rule doesn't have to be present. We could simply have a set of points. The set of points we are given is a relation.
A function occurs when we don't repeat the x value. Visually if we had two points stacked on top of each other, then we wouldn't have a function since it fails the vertical line test. A function happens when all x inputs leads to exactly one y output. If we had say { (-4,0), (2,-6), (-4,3) } then this wouldn't be a function since x = -4 repeats itself.
Since none of the x values repeat themselves in our given set, this means we have a function.
Side note: Any function is a relation, but not the other way around.

First right answer will get brainliest
answer:
B and C are correct.
explanation:
[tex]\hookrightarrow \sf x^2-5x+5[/tex] where ax² + bx + c
\\ Thus we can determine a = 1, b = -5, c = 5 \\
using quadratic equation:
[tex]\rightarrow \sf x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{2a} \ \ when \ \ ax^2 + bx + c = 0[/tex]
[tex]\hookrightarrow \sf x_{1,\:2}=\dfrac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:1\cdot \:5}}{2\cdot \:1}[/tex]
[tex]\hookrightarrow \sf x=\dfrac{5+\sqrt{5}}{2},\:x=\dfrac{5-\sqrt{5}}{2}[/tex]
Answer:
B and C
Step-by-step explanation:
[tex]x^2-5x+5=0[/tex]
⇒ a = 1, b = -5, c = 5
Using quadratic formula:
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]
[tex]\implies x=\dfrac{5\pm\sqrt{(-5)^2-4\cdot 1 \cdot 5} }{2\cdot 1}[/tex]
[tex]\implies x=\dfrac{5\pm\sqrt{5}}{2}[/tex]
The set of all numbers less than or equal to -1.
Answer:
anything before -1 is lower than -1. -1 = -1
Step-by-step explanation:
-10, -9, -8, -7, -6, -5, -4, -3, -2 etc. are in a sense before -1 on a time line and they are all less than -1
Set B represents the set of all the natural numbers less than or equal to -1
[tex]\rm B=\{-\infty ...........-4,-3,-2,-1\}[/tex]
if we include all the numbers the range of set includes every number from
[tex]\rm -\infty \; to -1[/tex] so the set is represented by K
[tex]\rm K = \{ -\infty ,.....-1\}[/tex]
In Mathematics a set is a collection of objects/elements that are constrained by some particular condition.
Let us consider a situation where "S" is the set and the elements are represented by "x"
A set is always denoted in curly braces. Expression (1) represents the set
[tex]\rm S =[/tex] { [tex]\rm x_1.x_2,x_3, x_4,x_5........x_n[/tex]}...........(1)
Set S has elements that are represented as [tex]\rm x_1[/tex][tex]\rm\\where \; i \; represents\; the\; index\; of \; the \; element\\n = number\; of \; elements \; in \; the \; set \; x[/tex]
The set of all the natural numbers less than or equal to -1 is the set of all the negative integers including -1.
So let us say B represents the set of all the natural numbers less than or equal to -1 . Then we can write it as follows
[tex]\rm B=\{-\infty ...........-4,-3,-2,-1\}[/tex]
Set B represents the set of all the natural numbers less than or equal to -1
if we include all the numbers the range of set includes every number from
[tex]\rm -\infty \; to -1[/tex] so the set becomes
[tex]\rm K = \{ -\infty ,.....-1\}[/tex]

A. 294 cu. units
B. 1008 cu. units
C. 196 cu. units
D. 112 cu. units
Answer:
C) 196 cu. units
Step-by-step explanation:
Volume = lwh/3
= 7 x 7 x 12 / 3
= 588/3
= 196
The volume of a square pyramid is 196 cubic units.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
From the given figure, side of square base is 7 units and height is 12 units.
We know that, the volume of square based pyramid =a²h/3.
Now, volume of a pyramid = 1/3 ×7²×12
= 49×4
= 196 cubic units
Therefore, the volume of a square pyramid is 196 cubic units.

Why do you think y= ax+b is called a linear equation
Please help
Answer:
Y=mx+b Is a linear equasion because if you plot the x and y on a graph it always shows a straight line.
Step-by-step explanation:
For example, y=7x+9,
When x is 1 y is 16, and
when x is 2 y is 23.
When you put those two points on a graph and connect the dots with a ruler, you get a straight line, and you will automatically find that when x is 3 y is 30.
Step-by-step explanation:
Hey there!
Reason:
The power of the term is one.It can be graphed in a at. line on graph.You can simply define linear equation as the equation which has two variables with 1 exponent.

2. y=3/4x+10
3. y=-5x-2
4. y=12x-6
5. y=1/2x+9
Step-by-step explanation:
for numbers 2, 4, 3, and 5 all you have to do is look at the slope they give you. in a linear equation (y=mx+b) the m is the slope. because there is only one equation with the slope they give you, that is the corresponding answer. but for 1, its a bit more complicated. because they give you a point you have to plug the x value into your equation. for exaple for 1. they give you 0 as the x value so you plug it into one of the equations. and if that equation gives you 7 as the y, then you have your answer.

3. Mrs. Galicia started a savings account for her family and started it with an initial deposit of $1600. The account earns 3.75% interest compounded quarterly.
(a) Write an equation to represent the anount of money in the account as a function of time in years.
(b) How much money will be present in the account in 5 years. *please show plug in step*
Hey there!
--› Initial deposit: 1600
--› rate = 3.75%
a) First, convert R as a percent to r as a decimal
r = R/100
r = 3.75/100
r = 0.0375 rate per year,
Substitute into formula
= A = P(1 + r/n)nt
A = P(1 + 0.0375/4)^4t
A = 1,600.00(1 + 0.009375)^4t
b)
A = 1,600.00(1 + 0.009375)^4t
A = 1,600.00(1 + 0.009375)^4(5)
A = 1,600.00(1 + 0.009375)^(20)
A = $1,928.28
The amount of money that will be present in the account in 5 years is P(5) = $1923.36
Exponential equationsThe standard exponential equations is expressed as:
p(t) = p0(1+r)^t
where:
Po is the initial deposit = $1600Rate "r" =3.75% = 0.0375time "t" = 5 yearsSubstitute
P(t) =1600(1+ 0.0375)^t
P(t) = 1600 (1.0375)^t
Hence the equation to represent the aount of money in the account as a function of time in years is P(t) = 1600 (1.0375)^t
If t =5 years
P(t) = 1600 (1.0375)^t
P(t) = 1600 (1.0375)^5
P(5) = $1923.36
Hence the amount of money that will be present in the account in 5 years is P(5) = $1923.36

1. What is the difference between a line and a line segment?
A. A line is a figure formed by two opposite rays with a shared endpoint, a line segment is a part of
a line that extends forever in one direction.
B. A line is a specific location that is represented by a dot, a line segment is a specific location
represented by two dots.
C. Aline is a portion of a line consisting of two points and all the points between them, and a line
segment is a figure formed by two opposite rays.
D. Aline is a figure formed by two opposite rays and a shared endpoint, and a line segment is a
portion of a line consisting of two points and all the points between them.
Explanation:
Basically a line goes on forever in both directions. A ray only goes off forever in one direction. If we glue together two rays that point in complete opposite directions (eg 1 points north, the other points south) then we form a line.
A line segment is a piece of a line. It doesn't go on forever in either direction. It has 2 endpoints and has a set fixed length. If you know the coordinates of each endpoint, you can use the distance formula to find that length.
