Answer:
There is no real solution
Step-by-step explanation:
If you are finding the square root of a number, it cannot be negative. No number can be multiplied by itself to get a negative number. Negative numbers multiplied with themselves make a positive number. Positive numbers are obviously going to stay positive. Therefore there is no square root of -9
Answer:
y = 1.5
Step-by-step explanation:
Given x is inversely proportional to
, then the equation relating them is
y =
← k is the constant of proportion
To find k use the condition when x = 8, y = 2
2 =
=
=
( multiply both sides by 3 )
6 = k
y =
← equation of proportion
When x = 15 , then
y =
=
=
=
= 1.5
Add, then subtract and that’s your answer!
