how do i solve this??
Answer:
J (3; 9)
Step-by-step explanation:
Imagine each distance like a triangle and use Pythagorean theorem.
To illustrate I drew triangle ΔLON in the picture
Finding the distance between LN.
LO = [tex]y_{L} - y_{O}[/tex] = 5 - 1 = 4
NO = [tex]x_{N} - x_{O}[/tex] = 5 - 4 = 1
According to Pythagorean theorem
[tex]LN^{2} = LO^{2} + NO^{2}[/tex]
[tex]LN^{2}[/tex] = [tex]4^{2} + 1^{2}[/tex] = 17
LN = [tex]\sqrt{17}[/tex] (LN > 0)
Since ΔMLN ≅ ΔKLJ, JL = LN (they are clearly equal triangles)
Mark J coordinates as (x; y)
Draw another triangle JOL, ∠JOL = 90°)
OJ is parallel with x axis and OL is parallel with y axis. O coordinates then are (4; y)
OL = y - 5
OJ = 4 - x
Note that ΔLON = ΔJOL, so OL is the same as LO and therefore
OL = LO = y - 5 = 4;
y = 9
OJ = NO = 4 - x = 1
x = 3
So the coordinates of J are (3; 9)
Similarly find the coordinates of K

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%

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
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

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

Write a function rule for the table.
A. f(x) = x + 2
B. f(x) = x – 2
C. f(x) = –2x
D. f(x) = 2x
Answer:
D.
Step-by-step explanation:
f(x) increases by 2 as x increases by 1 x value.
We know it isn't A since and x value plue 2 would not equal the y value.
But if you multiply each x-value by 2 you get f(x)
D is the equation for f(x)

10. Harmony places the letters in the word DECEMBER into a bag. A letter will be randomly
selected and not replaced. Then another letter will be selected. What is the probability of
Hormony selecting a C and then an E?
Answer:
3/56
Step-by-step explanation:
There are 8 letters in the word DECEMBER. The probability of picking a C first is 1/8, since there's only one C. Since the letter is not replaced, there are now 7 letters to choose from, out which 3 of those are the letter E. Therefore, the probability of picking an E second is 3/7. The total probability then is equal to [tex]\frac{1}{8}[/tex] times [tex]\frac{3}{7}[/tex], which is equal to [tex]\frac{3}{56}[/tex].

Table A represents a _______
function.
Table B represents a _______
function.
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.

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
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

B. 29,309
C. 104,595
D. 36,259
Can someone answer this please with an explanation.
Answer:
x=92
Step-by-step explanation:
those to angles are supplementary meaning that they add up to equal 180
so you set up the equation 180=x+x-4
180=2x-4
step 1 add 4 to each side
184=2x
step 2 divide each side by 2
x=92
so the angles equal 92 and 88
Answer:
92°
Step-by-step explanation:
180 degrees on a straight line.
2x - 4 = 180
2x = 184
X = 92°
