Answer:
Step-by-step explanation:
Use the table to find the slope and y-intercept
<u>Find the slope:</u>
- m = (6 - 4)/(3 - 1) = 2/2 = 1
<u>Find b using the pair (1, 4):</u>
- 4 = 1*1 + b
- b = 4 - 1
- b = 3
<u>The line is:</u>
The y-intercept is 3
Answer:option 3
Step-by-step explanation:
Your answer is ..
First,
we have to turn our mixed fractions into an improper fraction.
=4 1/8 which is 33/8(4 x 8 + 1).
Our next mixed fraction,
we have 1 1/7 which is 8/7(1 x 7 + 1).
Now, we have the get the same denominator in order to subtract.
SO, both 8 and 7 goes in to 56. So we multiply both mixed fractions to get the same denominator.
(Tip: what ever you do to do numerator, you do to the denominator; and the other way around).
33/8 : 33*7=231 and our denominator, 8*7=56
So our improper fraction now,
231/56
Our next fraction 8/7,
7*8= 56 and our numerator 8*8=64.
=64/56
So, now we subtract.
231-64= 167 and our common denominator. 167/56
Now we divide 167 by 56 which is 2 and remainder is 55.
So, you should end up with a mixed fraction, 2 55/56.

Step-by-step explanation:
If we add the angles inside a triangle, we must have 
. So we have an 
angle and an 
angle, their sum is 
, so the missing angle must be 
Answer:
Option A and C have rotational symmetry.
Step-by-step explanation:
The graph of odd functions have rotational symmetry about its origin.
Here the first graph is a graph of f(x)=
which is an odd function bearing an exponent of 3.
A function is "odd" when we plug in any negative value in 
then it gives negative of .
And we also know that when a graph is mirroring about the y-axis then it is an even functions.
For even functions we have reflection symmetry rather than rotational symmetry.
The second graph is a graph of 
which is an even function as we can see that its graph is mirroring about the y-axis.
The third graph is a graph of an ellipse which is possessing rotational symmetry.
The order of symmetry of an ellipse is generally 2.
Order of symmetry:
The order of rotational symmetry of an object is how many times that object is rotated and fits on to itself during a full rotation of 360 degrees.
So graph A and C have rotational symmetry.
