Answer:
function : 2 and 3
Step-by-step explanation:
a function cant have any overlapping points on the x axis, if you can draw a line up and down (vertical) and it hits two points then it isn’t a function

Answer:
x = 16
Step-by-step explanation:
Corresponding sides are proportional.
BE/CD = AE/AD
20/(3x+8) = (x-1)/(x-1+27)
20(x+26) = (3x+8)(x -1)
In standard form, this is ...
3x^2 -15x -528 = 0
x^2 -5x -176 = 0 . . . . . . divide by 3
(x -16)(x +11) = 0 . . . . . . . factor
x = 16
__
This is the positive value that makes the product zero. x=-11 will also make the product 0, but gives negative segment lengths in the geometry. It is an extraneous solution.
Answer:
my answer is A. you only need substitute n from 1 to 4
Answer:
Midpoint( .5,-2.5)
Step-by-step explanation:
To find the midpoint, add the x coordinates and divide by 2 and then add the y coordinates and divide by 2
x: (-1+2)/2 = 1/2=.5
y: (-9+4)/2 = -5/2 = -2.5
Midpoint( .5,-2.5)
