Answer:
x = {-4, 4}
Step-by-step explanation:
Subtracting 3 gives ...
5x^2 = 80
Dividing by 5, we get ...
x^2 = 16
Taking the square root gives the solutions ...
x = ±4
The smaller value of x is -4; the larger value is 4.
Answer:
A couple of hundreds
Step-by-step explanation:
In my brain
-2
Divide each term (-4x = 8 by -4)
Cancel the common factor of -4
x = 8/-4
THEN DIVIDE
x=-2
The range of the relation is 35,40,45,60,75
Reason being in relation range is the set of all second elements of ordered pairs (y-coordinates).
