Answer:
y = 2.4
Step-by-step explanation:
If y varies inversely as x, it means there's an inverse relationship between y and x, that is if x is increasing, y is decreasing and vice versa. In such instance, we have to find the constant of proportionality "k"
Hence,
y~1/x
y=k/x
When y =-6 and x =-2, we insert these values to find the value of the constant "k"
-6 = k/-2
k = 12.
Using this value of k to determine value of y when x =5 becomes:
y = 12/5
y = 2.4
-4x^2-5(x+3)+x^2 :
-4x^2-5x-15+x^2
-3x^2- 5x -15
Answer:
(0,-3) because its the coordinate
