Istance squared = (X2 - X1)^2 + (Y2 - Y1)^2
<span>distance squared = (-2 - 3)^2 + (4 - -2)^2 </span>
<span>distance squared = (-5)^2 + (6)^2 </span>
<span>distance squared = 25 + 36 </span>
<span>distance squared = 61 </span>
<span>Therefore; distance = square root of 61 = 7.8 approximately </span>

- 1 1/10 + (-1 2/5)
- 1 1/10 + (-1 4/5)
-2 5/10
-2 1/2
Answer:
(c) 9
Step-by-step explanation:
You can't have a repeated x-value in a function.
8 is taken by (8, 7)
7 is taken by (7,-6)
-4 is taken by (-4, 5)
9 is the only number that is not taken by any other point yet.
Remember that for a relationship to be a function it can't have repeated x-values. However, it doesn't matter to have the same x and y values!
Hope this helped!
Answer:
X = 2 or X = -10
Step-by-step explanation:
We know either3x+12=18or3x+12=−18
3x+12=18(Possibility 1)
3x+12−12=18−12(Subtract 12 from both sides)
3x=6
3x
3
=
6
3
(Divide both sides by 3)
x=2
3x+12=−18(Possibility 2)
3x+12−12=−18−12(Subtract 12 from both sides)
3x=−30
3x
3
=
−30
3
(Divide both sides by 3)
x=−10
Answer:
x=2 or x=−10
Those are positive numbers.
Those that are less than zero are called negative numbers.
Zero itself can be considered both, or neither.
