is an example of a greatest integer function.
The greatest integer function takes in a real number and gives out the greatest integer that is less than that number.
So the domain of g(x) is all real numbers
<b> Any real value you plug in to the above function will be defined </b>
What you do is to substitute the first number for x and the second for y:
(x+7)y=10
a):
(-9+7)*-5=10
(-2)*-5=10
10=10
yes, it's a solution!
b)
(-8+7)10=10
-1*10=10
-10=10
no, not a solution!
c) (-2+7)2=10
5*2=10
yes, a solution!!
d) (3+7)*5=10
50=10
no, not a solution!
Answer:
(-2,-4)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates and divide by 2
( -6+2)/2 = -4/2 = -2
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
( -1+-7)/2 = -8/2 = -4
(-2,-4)
