How to find domain and range from co-ordinate pairs?
If (x,y) is a pair x is domain,y is range.Now starting and ending point on x axis
(-2,0)(4,0)Hence
[tex]\ \ \sf\longmapsto D_f=\{-2,4\}[/tex]
Starting and ending point on y axis
(0,0)(0,-3)Hence
[tex]\ \ \sf\longmapsto R_f=\{0,-3\}[/tex]

If one leg of a right triangle has a length of 7 and the hypotenuse has a length of 12, what is the length of the other leg?
A
19
B
V193
с
195
D5
Answer:
sqrt(95)
Step-by-step explanation:
c^2 = a^2 + b^2
12^2 = 7^2 + b^2
144 = 49 + b^2
95 = b^2
sqrt(95) = b

Which point will going to be in y=-4+6
Answer: (-4,22)
I got this by solving the equation on a graph.
When solving 8,411 ÷ 52, you decide to start by subtracting 100 groups of 52. What is the remainder?
Answer:
I think that the remainder would be 39. I am not 100% sure however.
Step-by-step explanation:
I started by doing 8411-5200 because 100 groups of 52 is 5200. I got 3211 and then divided that by 52. I got 62 r 39. Hope this helps!!
Answer: remainder : 39

HELP!! DONT STEAL MY POINTS OR ANSWER AND THEN DELETE IT!! Which is the orthocenter of a triangle with vertices (-2, 1), (3, 4), and (3, -4) ?
Answer:
(0, 1)
Step-by-step explanation:
The orthocenter is the point of intersection of the altitudes of the triangle. Each altitude is a line through a vertex and perpendicular to the opposite side.
In the attached, we labeled the points A, B, C in the order given. Side BC of the triangle is vertical, so the horizontal line through A will have equation ...
y = 1
The line AC can be seen on the graph to have slope -1, so the altitude through point B will have slope 1. Its equation will be ...
y = x+1
Then the point of intersection will be where ...
y = y
1 = x+1
0 = x
That is, the orthocenter is the point (x, y) = (0, 1).

A 140-meter rope is cut into two pieces. One piece is four times as long as the other. How long is each piece?
Answer:
28meters and 112meters
Step-by-step explanation:
one piece is x
the other is 4x
therefore; 4x+x=140
5x= 140
divide both sides by 5
x=28
4x=4(28)
=112
Write a linear function rule for the data in the table
Answer:
B. y= -2x+3
Step-by-step explanation:
1) the slope-interception form is: y=s*x+i, where s - slope, i - interception are unknown numbers;
2) if y(0)=3, then i=3, it means the equation is y=s*x+3;
3) if to substitute x=1; y=1 into the equation y=s*x+3, then s= -2. It means, the initial equation is y= -2x+3.
4) finally, the correct answer is B.

Write a fraction setting the vertical length of the larger triangle over its horizontal length. What does this fraction represent?
Answer:
See belowStep-by-step explanation:
Vertical length of the larger triangle is:
0 - (-4) = 4Horizontal length of the larger triangle is:
0 - (-6) = 6The fraction:
4/6 = 2/3This fraction represents the slope of the hypotenuse (or the red line)
Horizontal length:-.
[tex]\\ \sf\longmapsto |0-6|=|-6|=6units[/tex]
Vertical length:-
[tex]\\ \sf\longmapsto |0-4|=|-4|=4units[/tex]
Fraction:-
[tex]\\ \sf\longmapsto \dfrac{x}{y}=\dfrac{4}{6}=\dfrac{2}{3}[/tex]

Jade got a 90% on her math quiz. She had 36 questions correct. How many questions did Jade get wrong?
Answer:
4 questions
Step-by-step explanation:
90% is the same as multiplying a number by 0.9. Let's say the number of questions on the quiz is x. This means the amount she got right was 0.9x. We are given this is 36, so we can set them equal and simplify:
0.9x = 36
x = 40
She must have gotten 40 - 36, or 4 questions wrong.

To find the quotient of 8- 3. multiply 8 by
1
8
o
1
3
03.
08.
to divide by a fraction, you multiply by the reciprocal which just means reversing the fraction. so 8/ 1/3 is the same as 8 x 3.

PLS HELP WILL MARK BRAINLIEST, PLS HURRY
Answer:
A. 2x - 1
Step-by-step explanation:
We want the price of each notebook, so we will get this equation.
(4x^2 + 2x + 1) / (8x^3 - 1) [ The " / " sign means I wrote as a fraction. ]
After that, we will use this method to factor ( 8x^3 - 1 ).
a^3 - b^3 = ( a - b )( a^2 + ab + b^2 )
1 can be wrote as 1^3 as we still get the same answer.
8^3 - 1^3 = ( 2x - 1 )( 4x^2 + 2x + 1)
So, we will get this.
(4x^2 + 2x + 1) / ( 2x - 1 )( 4x^2 + 2x + 1)
Now, we can cross out the ( 4x^2 + 2x + 1 ).
We will be left with 1 / ( 2x - 1 ).
Flip it and we will get ( 2x - 1 )
And that is the answer.
I hope it helps.
What fraction of 3 is 1
1/3Answer:
Step-by-step explanation:
Which numbers are solutions of 3m<4m+5?
Options:
-10
-5
-2
8
Answer:
-2 and 8.
Step-by-step explanation:
Isolate the m variable.
3m<4m+5
Subtract 4m from both sides.
-m<5
Divide both sides by -1.
m>-5
Solutions to this inequality are any number greater than -5 which is -2 and 8.

write an equation in slope intercept form for the line with slope -1/4 and y intercept 1. 25 point!!
Answer:
An slope-intercept form equation is written as y=mx+b. “m” is the slope and ”b” is the y-intercept. When we substitute the given values, the equation of the line in slope-intercept form is y=-1/4x+1.

9n - 14 =5n + 58
9n-14=5n+58
9n-5n=58+14
4n=72 / 4
n=18
Hello! (:
9n-14=5n+58
Move all the variables to the left, using the opposite operation:
9n-5n=58+14
9n-5n=72
4n=72
Divide both sides by 4 to isolate n:
n=18
