Determine whether each relation is a function. If so, provide the domain and range.
Answer:
Not a function
Step-by-step explanation:
A relation is considered a function if and only if every input value has exactly one output value.
The relation given does not satisfy the condition of a function. The input value, height = 160 cm, is related to different output values (age).
Therefore, the relation is not a function.
What is an equation of the line that passes through the points (4, 3) and (-6, 3)?
Answer:
Step-by-step explanation:
(4,3)(-6,3)
3-3/-6-4
m=0
y=3
Answer:
y=3
Step-by-step explanation:
Something that I notice about this is that the 2 y coordinates are the same
This means that the line isn't increasing nor decreasing, it's constant
if we look at the y=mx+b
we have, so far,
y=0x+b
we just need be
we know that when x=4 y=3 so we have
3=(0)(4)+b
b=3
so the answer is just y=3
Which graph represents the solution 2x - 5y <3
Answer:
There is no picture... But here is a representation of the inequality on a graph
The graph 2x - 5y < 3 cut the x-axis at the point (3,0) and the y-axis at the point (0,-0.6).
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.
Given inequality is 2x - 5y <3. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
When the inequality 2x - 5y < 3 is plotted on the graph it covers the region which is less than the line 2x - 5y < 3. The graph cut the x-axis at the point (3,0) and the y-axis at the point (0,-0.6).
The graph of the given inequality is attached with the answer below.

2/9 of the students in a school are in sixth grade.
a. How many sixth graders are there if the school has
90 students?
b. How many sixth graders are there if the school has
27 students?
c. if the school has x students write an expression for the number of students of sixth graders in terms of x
d. how many students are in the school of 42 of them are in 6th grade
Answer:
a) 20 sixth graders.
b) 6 sixth graders.
c) 2/9x sixth graders.
d) 189 students in the school.
Step-by-step explanation:
a) 2/9 of 90 = 2/9 * 90 = 20 students.
b) 2/9 of 27 = 2/9 * 27 = 6 students.
c) 2/9 of x = 2/9x
d) 42 = 2/9x so solve the equation: x = 189 students.
If we have 90 students in the school then we will have 20 sixth grade students.
a. From the details of the question, we have 2/9 of the students in the school in sixth grade. Hence;
Number of students in sixth grade = 2/9 × 90 = 20 sixth grade students
b. If the school has 27 students, number of sixth graders = 2/9 × 27 = 6 sixth grade students
c. If we have x students in the school, the number of sixth graders = 2/9 × x = 2/9x students
d. If we have 42 students in sixth grade, the number of students in the school is;
2/9 × x = 42
x = 9/2 × 42 = 189 students

HELPPPP!!! PLEASEEEE I’M FAILING ALGEBRA AND I NEED HELP WITH THIS QUESTION
a/b The decay can be modeled by this equation, (1 - r), the r being the rate of decay. So it would be 1-0.115. (0.115 is your answer for a) You have to convert the percent into a decimal by moving the deicmal place two places to the left. 0.885 is your answer for b.
c. For function notation, that just means write an equation. So you want your decay times your inital. V(t)=15000(0.885)^x. We get the V(t) from the directions that they want us to put it in; it's basically y.
d. Since it's two years, plug in 2 for x. This shows the decay after two years
V(t)=15000(0.885)^2
e. As with d, plug in 10 for x. V(t)=15000(0.885)^t

Answer:
1. 17.8 cm
2. 32.0 cm
3. 15.9 m
Step-by-step explanation:
1. Determination of the length of the arc.
Radius (r) = 6 cm
Angle at the centre (θ) = 170°
Pi (π) = 3.14
Length of arc (L) = ?
L = θ/360 × 2πr
L = 170/360 × 2 × 3.14 × 6
L = 17/36 × 37.68
L = 17.8 cm
2. Determination of the length of the arc.
Diameter (d) = 13 cm
Angle at the centre (θ) = 282°
Pi (π) = 3.14
Length of arc (L) = ?
Next, we shall determine the radius. This can be obtained as follow:
Diameter (d) = 13 cm
Radius (r) =?
r = d/2
r = 13/2
r = 6.5 cm
Finally, we shall determine the length of the arc. This can be obtained as follow:
Radius (r) = 6.5 cm
Angle at the centre (θ) = 282°
Pi (π) = 3.14
Length of arc (L) = ?
L = θ/360 × 2πr
L = 282/360 × 2 × 3.14 × 6.5
L = 282/360 × 40.82
L = 32.0 cm
3. Determination of the length of the arc.
Radius (r) = 11 m
Angle at the centre (θ) = 83°
Pi (π) = 3.14
Length of arc (L) = ?
L = θ/360 × 2πr
L = 83/360 × 2 × 3.14 × 11
L = 83/360 × 69.08
L = 15.9 m

Refer to the Exhibit Teacher's Salary. Find the probability that a randomly selected teacher receives a salary of $45,000 or more. (Do not round your answer)
Answer:
[tex]P(x \ge 45000) = 0.77935[/tex]
Step-by-step explanation:
Given [Missing from the question]
Exhibit Teacher's Salary:
[tex]\bar x=50000[/tex]
[tex]s = 6500[/tex]
Required
Calculate [tex]P(x\ge 45000)[/tex]
First, we calculate the z score
[tex]z = \frac{x - \bar x}{s}[/tex]
[tex]z = \frac{45000 - 50000}{6500}[/tex]
[tex]z = \frac{-5000}{6500}[/tex]
[tex]z = -0.77[/tex]
[tex]P(x \ge 45000) = P(z \ge -0.77)[/tex]
[tex]P(x \ge 45000) = 1 - P(z \le -0.77)[/tex]
From the table:
[tex]P(z \le -0.77) = 0.22065[/tex]
So, we have:
[tex]P(x \ge 45000) = 1 - 0.22065[/tex]
[tex]P(x \ge 45000) = 0.77935[/tex]

-4x – 4y = 0
4x + 4y = 0
Answer:
(0,0) or Infinitely many solutions.
Step-by-step explanation:
-−4x−4y=0
−4x−4y+4y=0+4y(Add 4y to both sides)
−4x=4y
−4x/-4= 4y/-4
(Divide both sides by -4)
x=−y
4x+4y=0
4(−y)+4y=0
0=0
