A function is a relation in which no two ordered pairs have the same first component and different second components.
We need to ask ourselves, does every first element (or input) correspond with EXACTLY ONE second element (or output)?
In this case, the answer is no. The input value of 1 goes with two output values, -1 and -5. The same goes with the input value of 2, which also goes with two output values: -2 and -4.
It only takes one input value to associate with more than one output value to be invalid as a function.
I also did the Vertical Line Test to show why Option 2 is not a function. The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.
However, the graph shows that the two vertical lines crossed the graphed twice (there are 2 points in each line). The graphed points failed the vertical line test. Therefore, Option 2 is NOT a function.

The speed (v) of a gear varies inversely as the number of teeth (t). If a gear that has 48 teeth makes 20 revolutions per minute, how many revolutions per minute will a gear that has 30 teeth make?
I'll give Brainliest! Please no links
Answers
Answer:
32 revolutions per minute(rpm)
Step-by-step explanation:
v inversely proportional to t
so if v increases t will decrease and vice versa
inverse equation is xy=k
xy=k
48×20= 960 (revolutions)
then you'll take k(960) and divide it by number of teeth
so..
960/30 = 32 revolutions per minute
What represents the recursive formula for the arithmetic sequence an=7-3(n-1)
Answers
Answer:
[tex]\left\lbrace\begin{aligned}& a_{1} = 7 \\ & a_{n+1} = a_{n} - 3 && \text{for $n \ge 1$}\end{aligned}\right.[/tex].
Step-by-step explanation:
An arithmetic sequence could be defined using only two pieces of information:
The first term of this sequence, [tex]a_{1}[/tex].The common difference between two consecutive terms of this sequence, [tex]d[/tex].The arithmetic sequence in this question is given in the explicit form, [tex]a_{n} = 7 - 3\, (n - 1)[/tex], which is equivalent to [tex]a_{n} = 7 + (-3)\, (n - 1)[/tex]. In the explicit form, [tex]a_{1}[/tex] and [tex]d[/tex] are described in the same equation:
[tex]\text{$a_{n} = a_{1} + d\, (n - 1)$ for $n \ge 1$}[/tex].
Compare [tex]a_{n} = a_{1} + d\, (n - 1)[/tex] with [tex]a_{n} = 7 + (-3)\, (n - 1)[/tex]: [tex]a_{1} = 7[/tex] whereas [tex]d = -3[/tex].
When an arithmetic sequence is given in the recursive form, [tex]a_{1}[/tex] and [tex]d[/tex] are specified in two separate equations:
[tex]\left\lbrace\begin{aligned}& a_{1} = a_{1} \\ & a_{n+1} = a_{n} + d && \text{for $n \ge 1$}\end{aligned}\right.[/tex].
In this question, it was found that [tex]a_{1} = 7[/tex] whereas [tex]d = -3[/tex]. Hence, the corresponding recursive formula for this arithmetic sequence would be:
[tex]\left\lbrace\begin{aligned}& a_{1} = 7 \\ & a_{n+1} = a_{n} + (-3) && \text{for $n \ge 1$}\end{aligned}\right.[/tex].

The larger of two consecutive integers is 13 greater than four times the smaller. Find the integers. -3, -4 7, 8 3, 4
Answers
Answer:
The integers are -3 and -4.
Step-by-step explanation:
Two consecutive integers are an integer and the one just greater or just less than the4 first one, such as 5 and 6, or -8 and -9.
If the smaller integer is x, then the next greater integer is x + 1.
x + 1 = 4x + 13
-3x = 12
x = -4
x + 1 = -3
Answer: The integers are -3 and -4.
Check:
Smaller integer: -4
Larger integer: -3
4 times smaller integer = 4 * (-4) = -16
13 greater than 4 times smaller = -16 + 13 = -3 = greater integer
-3 and -4 is the correct answer.
Answer:
-3 and -4

Claire's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This relationship can be represented by the equation y represented by the equation y = 56 + 7.1x, where y represents the expected quiz score and x represents hours spent on homework that week. What is the meaning of the x-value when y = 92?
the change in expected quiz for every additional one hour students spend on their homework.
a student's expected quiz score if they spent 1 hours on their homework.
the number of hours a student should spend on their homework to expect a score of 92 on the quiz.
a student's expected quiz if they spent 92 hours on their homework.
Answers
Answer: t = 5.7 hours
Step-by-step explanation:
y=56+7.1x where x is the time spent studying. If y=92, this equation would preduct that the student spent t hours studying. Find t:
92=56+7.1x
36=7.1t
t = 5.07 hours to achieve the 92 score.

C. No; the sum of angle measures in spherical geometry is always greater than
180, but there is not a particular number they must sum to.

Answers
When two angle measure of a triangle are given in spherical geometry: The sum of angle measures in spherical geometry is always greater than 180, but there is not a particular number they must sum to. Choice C (No) is correct
According to the question;
Two angle measures of a triangle in spherical geometry are given.However, unlike in plane geometry where affirmatively, the sum of angles in a triangle is equal to 180°.
In spherical geometry;
The totality of the angles of a triangle on a sphere is given as 180°(1 + 4x), where x is the fraction of the sphere's surface that is enclosed by the triangle. For any positive value of x, which in each case exceeds 180°.

Step 1: Convert both mixed numbers into fractions.
2 3/4 = 11/4
3 5/6 = 23/6
Step 2: Find GCF by multiplying both fractions by opposing denominators
11/4 = 66/24 (11 * 6 = 66, 4 * 6 = 24)
23/6 = 92/24 (23 * 4 = 92, 6*4=24)
Step 3: Add both fractions
92/24 + 66/24 = 158/24
Step 4: Simplify
158/24= 79/12 = 6 7/12 miles

One week, Sharon worked 18 hours as a lifeguard and 12 hours at a concession stand and earned $228. The next week, she earned $254 for 24 hours as a lifeguard and 8 hours at the concession stand. How much per hour does she get paid for each job?
Answers
Answer:
She is paid $6.25.hour at the concession and $8.50 as a lifeguard.
Step-by-step explanation:
We know:
18 hours as a lifeguard
12 hours at concession
Total earned = $228
18L + 12C = 228
Then:
24 hours as a lifeguard
8 hours at concession
Total earned = $254
24L + 8C = 254
Move one equation around to get one variable by itself: in this case we can solve for L:
18L + 12C = 228
18L = 228 - 12C
L = (228/18) - (12/18)C
Plug in for L:
24((228/18) - (12/18)C) + 8C = 254
Solve for C:
C = 6.25
Now that we know C, plug in value for C and solve for L:
18L + 12(6.25) = 228
L = 8.5
So she is paid $6.25.hour at the concession and $8.50 as a lifeguard.

Step-by-step explanation:
JK + KL = JL , substitute values
4x + 6 + 7x + 15 = 129 , that is
11x + 21 = 120 ( subtract 21 from both sides )
11x = 99 ( divide both sides by 11 )
x = 9
Then
JK = 4x + 6 = 4(9) + 6 = 36 + 6 = 42
KL = 7x + 15 = 7(9) + 15 = 63 + 15 = 78

In this lesson you discovered the Angle Blsector Conjecture. Write the converse of the Angle Blsector Conjecture. Do you think it's true. Why or why not?
Answers
Answer: The converse is that if a point is on the interior of an angle and is equidistant from both sides of the angle, then the point lies on the angle bisector. This makes sense since the distance from a point and a side of the angle is a perpendicular line connecting the point to a side. And since it is equidistant from both sides, the perpendicular lines have to be congruent, it make sense if the point is on the angle bisector, the traingles would be congruent.
