Step-by-step explanation:
Given ( 0 , 3) and slope (m) = 2
Now the equation of line is
y - y1 = m ( x - x1)
y - 3 =2 ( x -0)
y - 3 = 2x
2x - y +3 = 0
which is the required equation
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
Answer:
8 miles
Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
no solution x=0
First, you calculate the total amount of parts : 2 + 5 = 7
Next, divide the number by the total amount of parts : 28 ÷ 7 = 4
After that, you multiply the answer by the amount of parts needed on both sides of the ratio : 4 × 2 = 8 and 4 × 5 = 20
Finally put these answers back into the ratio : 8:20
So there are 8 students in the play
To check, make sure both sides of the ratio add up to the original number : 8 + 20 = 28
