Answer:
Range
Step-by-step explanation:
The range of a graph tells you <u>all of the possible y-values</u> for it.
There is also the domain, which tells you all of the possible x-values.
For example, if you have this relation, that only has these points:
(1, 2) (2, 4) (3, 6)
Then the range is {2, 4, 6}. This means the "y" can ONLY be the numbers stated here.
The domain would be {1, 2, 3}.
Answer:
{-2,10}
Step-by-step explanation:
x^2 - 8x = 20
Take the coefficient of x
-8
Divide by 2
-8/2 =-4
Square it
(-4)^2 =16
Add this to each side
x^2 - 8x+16 = 20+16
x^2 - 8x+16 = 36
The left hand side becomes( x + (-8/2) )^2
(x - 4)^2 = 36
Take the square root of each side
sqrt((x - 4)^2) =±sqrt( 36)
x-4 = ±6
Add 4 to each side
x-4+4 = 4±6
x = 4±6
x = 4+6 x = 4-6
x = 10 x = -2
It must be 6 since the length sides r doubled and it's similar
What are the angles?
if all of them are below 90 degrees, it is acute.
if one angle is 90 degress, it is right
if one angle is more than 90 degrees, it is obtuse
Answer:
B.(2,1)
Step-by-step explanation:
The line segment AB will translate onto segment AB' by the translation,
(x+2, y+1)
You add 2 to the x value and 1 to the y value of segment AB.
