Please answer #11,#15,and #16.For #11, determine if the graph represents a function.For #15-16 find the domain and range of the function represented by the graph.
Answers
Problem 11
Answer: Not a function
Why not? Because it fails the vertical line test. It is possible to draw a single straight vertical line through more than one point on this blue curve.
Put another way: An input like x = 2 produces more than one output (y = 2 and y = 4 at the same time). If we wanted a function, we need any given input in the domain to produce exactly one and only one output.
=============================================================
Problem 15
Answers:
Domain: [tex]-4 \le x \le 2[/tex]Range: [tex]2 \le y \le 6[/tex]Explanation:
The domain is the set of allowed x values. The left-most point on the blue curve is when x = -4, which is the smallest item allowed in the domain. The largest value allowed is x = 2, as this occurs at the right-most point on the blue curve. Therefore, our domain here is [tex]-4 \le x \le 2[/tex]
The range is similar, but we focus on y values this time. The lowest the graph goes is y = 2, and the highest it goes is y = 6. So [tex]2 \le y \le 6[/tex] represents the range of possible y outputs.
For both the domain and range, both endpoints are included.
=============================================================
Problem 16
Answers:
Domain: [tex]2 < x < 7[/tex]Range: [tex]1 < y < 6[/tex]Explanation:
We follow the same idea as before. This time however, we have open holes which means that we do not include the endpoints.
The domain is [tex]2 < x < 7[/tex] since the curve spans from x = 2 to x = 7, excluding both of those x values. The range is [tex]1 < y < 6[/tex] for similar reasoning.
Notice how both problems 15 and 16 are functions because they pass the vertical line test. It is not possible to draw a single vertical line through more than one point on either blue curve.

Amount of paint (pints), y
4

25
How much paint should the painter expect to use to paint a wall with an area of 256 square feet?
Answers
Answer:
16 pints
Step-by-step explanation:
it seems like there's a pattern. when you divide x by 16, you get the result of y.
64/16 = 4
144/16 = 9
400/16 = 25
so to find the answer would be x/16 = y.
sqrt ft is x, pints is y.
we're looking for how many pints of pain we should use for 256 sqrt ft. we use that same equation, but replace x with 256, and solve for y.
256/16 = 16
therefore, your answer is 16 pints.

Samantha spent 40 minutes on homework sixty percent of that time was spent on language arts how many minutes were spent in language art
Answers
Answer:
i think its b.24 minutes
Step-by-step explanation:
sorry if im wrong
Answer:
Samantha spent 24 minutes on language arts.
Step-by-step explanation:
So, 60% = 3/5.
Since Samantha spent 40 minutes in total for homework, the 40 minutes would be the denominator. Let's have the variable "x" equal how many minutes she spent on language arts. If we line up the fractions, it will be like this:
3/5 = x/40
Since we know 5 x 8 = 40, we would also multiply the numerator by 8.
3 x 8 =24.
So, Samantha spent 24/40 minutes on ELA, which is 60% of the total time.
Illinois' population is now 12.5 million and decreasing by 0.1 million each year. On the other hand, Arizona's population is 6.9 million and increasing by 0.6 million each year. In how many years will the two states have the same population?
Answers
Answer:
8 years
Step by step guide:
100,000 x 8 = 800,000
600,000 x 8 = 4,800,000
6,900,000 + 4,800,000 = 11,700,000
12,500,000 - 800,000 = 11,700,000

The slope of Consider the line whose equation is 3x + y - 3 = 0. The slope of any line that is parallel to this line is any line that is perpendicular to this line is
Answers
Answer:
parallel : y = -3x + 3
perpendicular : y = 1/3x + 3
Step-by-step explanation:
rewrite 3x + y - 3 = 0
y = -3x + 3
parallel has the same slope
so
parallel : y = -3x + 3
perpendicular is negative reciprocal of the slope
so
-3x becomes 1/3x
so
perpendicular : y = 1/3x + 3

Find the equation of the line through the point (1, 16) that is parallel
to the given line. Write your final answer in slope-intercept form.
2y – 14x = 12
Answers
2y = 14x + 12 (add 14x to both sides)
y = 7x + 6 (divide all by 2 so we just have y and not 2y)
Parallel means it has the same slope but different intercept. So we need to know which intercept allows us to have a slope of 7 but go through the point (1, 16).
y = 7x + b
16 = 7(1) + b (substitute x & y)
16 = 7 + b (simplify)
9 = b (subtract 7 on both sides)
So the intercept is 9. So the equation of the parallel line would be y = 7x + 9.
And that answer is parallel to the original line y = 7x + 6; the whole line is shifted upwards by 3 units.

A jar has 20 marbles: 3 green, 12 blue, 5 red.
What is the probability of randomly choosing a red and then a green marble (keep the red marble when you choose it)?
Answers
Probability is defined as the likelihood or the certainty that an event is going to occur or happen.
The probability of randomly choosing a red and then a green marble is [tex]3/76[/tex].
The total number of marbles = 20
The number of green marbles= 3
The number of blue marbles = 12
The number of red marbles = 5
The probability of choosing a red marble = Number of red marbles / Total number of marbles
= 5/20
In simplest fraction form = [tex]\frac{1}{4}[/tex]
We are told in the question that you keep the red marble you choose, So this means the total number of marbles left reduces to 19
The probability of choosing a green marble is = Number of green marbles / New total number of marbles
= 3/19
Therefore, the probability of randomly choosing a red and then a green marble is
P (Red) x P(Green)
= 1/4 x 3/19
= [tex]3/76[/tex]

What is linear equations?
An equation is said to be linear if the highest power of a variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the standard form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present. A linear equation is one that has a degree of 1 as its highest value. No variable in a linear equation, then, has an exponent greater than 1. A linear equation's graph will always be a straight line.
How to calculate question by adding their values in the given equation?
firstly, the given equation is: [w2x-3]/10z
