Describe the graph of the equation y = 0. Is the equation a function?
vertical line; yes
horizontal line; yes
vertical line; no
horizontal line; no
Answer: B. horizontal line; yes
Use the slope-intercept form to find the slope and y-intercept.
Slope:
0
y-intercept:
(0,0)
Yes it is a function. It is a horizontal line.
Every point on this line is of the form (x,4) where x can be any number you want. The y coordinate is fixed at 4 and cannot change. Two points on this line are (0,4) and (1,4). The horizontal line goes through 4 on the vertical y axis.
Why is it a function? Because it is impossible to draw a vertical line through more than one point on the graph of y = 4. The graph passes the vertical line test. Put another way, for any x input, there is exactly one y output.
Side Note: y = 4 is the same as y = 0x+4. Note how its in the form y = mx+b
m = 0 is the slope
b = 4 is the y intercept
Step-by-step explanation: A. vertical line; yes
horizontal line; yes
Yes! Horizontal line represents a function y = f(x)
(1):Firstly, lets understand a function. For a function to be defined, we have a set of independent variables(inputs) (Domain), a set of dependent variables (outputs) (Codomain). And a relation between the variables.
(2): Each input in X must be related to exactly one output in Y. Or else it won't represent a function.. like in the following image.. y is a function of x.Because each element ofX has one& only one image in Y
C. vertical line; no

Answer:
Since 1/5 is 0.2
and 1/5 × 9 is 9/5
We can do 0.2 × 9
which you should get 1.8
OR you can do 0.2 + 0.2 + 0.2 +0.2 +0.2 + 0.2 + 0.2 + 0.2 + 0.2 (which is 0.2 added 9 times)
Which also results in 1.8
Answer:
she could mabey multiply 9x0.2=1.8
Step-by-step explanation:
it might be 1.8 because if 1/5=0.2 and she needs to find out what 9/5 is so
you need to multiple 9x0.2 but im not sure if im right

You have been assigned 40 homework assignments this marking period. You have completed 18 of them. What percent of homework assignments have you completed?
Answer:
45%
Step-by-step explanation:
Simply divide your partial amount (18 in this case) by your total (40), and you then multiply your answer from 18/40= .45 by 100, and you get 45. This is 45%
45% because math said so
18÷40= .45
.45•100=45

During a sale, a dress is marked down from a selling price of $ to a sale price of $. What is the percent markdown?
Complete question :
35%
Answer:
Step-by-step explanation:
Selling price = $68
Markdown price = $44.20
Percentage markdown :
Markdown / selling price * 100%
((68 - 44.20) / 68) * 100%
(23.8 / 68) * 100%
0.35 * 100%
= 35%
what fraction is greater than 1/5 and less than 1/3
The fraction 1/4 is greater than 1/5 and less than 1/3
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction that can be written as the form of p : q, which is equivalent to p / q.
We need to find the fraction that is greater than 1/5 and less than 1/3
Since we know that 1/5 < 1/4 < 1/3
When the numerator is less than the denominator, the fraction is called proper fraction, otherwise it is called improper fraction that proper fraction is also called fraction which is less than 1.
Therefore the answer is; 1/4

Use the Law of Cosines to write an expression equivalent to a. I need this answer urgently pls!
9514 1404 393
Answer:
a = √(b² +c² -2bc·cos(A))
a = √(c² -b²)
Step-by-step explanation:
For sides a, b, c, and opposite angles A, B, C, the general form of the law of cosines is ...
a² = b² + c² -2bc·cos(A)
An expression for 'a' can be written by taking the square root.
a = √(b² +c² -2bc·cos(A))
__
If you recognize that cos(A) = b/c, then a substitution can be made:
a = √(b² +c² -2(bc)(b/c)) = √(b² +c² -2b²)
a = √(c² -b²) . . . . . . . same as the Pythagorean theorem

A salesperson will earn a commission equal to 1/32 of the total sales. what is the commissions earned on the sales totaling 24000
Answer:
Step-by-step explanation: When dealing with fractions in the way they are used in this problem the word "of" (as in "1/32 OF the total sales") means to multiply.
the total sales") means to multiply.
So we can write an equation as:
c
=
r
⋅
s
Where:
c is the commission earned, what we are solving for in this problem.
r is the commission rate - 1/
32 in this problem
s is the total sales - $24,000 in this problem.
Substituting and calculating c gives:
c
=1/32 x $24,000
c=$24,000/
32
c

someone pls help mee with this question:) if you do tysm<33
Answer:
w = 35
Step-by-step explanation:
The angle adjacent to 125° is
180° - 125° = 55°
The 3 angles on the straight line sum to 180° , that is
90 + w + 55 = 180
w + 145 = 180 ( subtract 145 from both sides )
w = 35

Table C represents a _______
function.
Answer:
a:cubic
b:quadratic
c:linear
Step-by-step explanation:
Tables A, B, and C represent cubic, quadratic, and linear functions respectively.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
In the question, 3 functions in tabulated form is given, we draw the function on the graph then we observe that,
Table A, shows the cubic function because the graph with an increase of x increase and decrease multiple times.
Table B, shows the quadratic function, is shows the curve as of the parabola.
Table C, shows the linear relationship, as it forms a line on the graph.
Thus, tables A, B, and C represent cubic, quadratic, and linear functions respectively.
