Answer:
13. A
14. C.
Step-by-step explanation:
A relation is a function if there is only one y assigned to each x.
That is if you have a set of points, there should be no repeated x value.
So looking at {(0,0),(-2,4),(-2,-4),(-3,7)} this is not a function because you have two x's that are the same. A.
The slope-intercept form of a linear equation is y=mx+b where m is the slope and b is the y-intercept.
The y-intercept is where the graph goes through the y-axis at. It goes through at -1 so b=-1.
The slope is rise/run. So starting from the y-intercept (0,-1) we need to find another point to count the rise & run to... How about (3,1)? That works. You can do the counting if you want. You could also use the slope formula.
To use the slope formula, I just like to line the points up vertically and subtract vertically then put 2nd difference over the 1st difference.
(0,-1)
-(3,1)
--------
-3 -2
So the slope is -2/-3 or just 2/3.
So the equation is y=2/3 x-1
C.
Here’s the answer if you still need it -11/12 :)
Answer:
The first one is 8
The second one is 4
And the third one is 4
Step-by-step explanation:
Answer:
- b = 15
- c = 51
- c = 100
- b = 25.75
Step-by-step explanation:
Using the Pythagoras theorem equation:
Where 'c' is the hypotenuse and 'b' and 'a' the sides of the right triangle.
1) Here c = 17, a = 8 and b = ?
Then, using the above equation we can find the side b.
2) Here a = 24, b = 45 and c = ?
3) Here a = 28, b = 96 and c = ?
4) Here a = 17, b = ? and c = 28
Just in the 4 case x is an altitude.
I hope it helps you!
