As the y intercept lies on the x-axis, x=0
To find the y-intercept, put x=0 into the equation:

Therefore,the y-intercept=9.

Answer:
1/8
Step-by-step explanation:
1/2 of 1/4 is 1/8
Plug in 3a for x,
2(3a)^2 is 18a^2, then add five
Answer: 18a^2 +5
Substituting z = 5 into the first equation:
2x - y + 5 = -4
y = 2x + 9
Substituting y and z into the third equation
-2x + 3(2x + 9) - 5 = -10
4x + 27 = -5
x = -8
y = 2(-8) + 9 = 7
z = 5
Answer:
82 minutes.
Step-by-step explanation:
So first calculate the percentage 37 minutes is. It is 45%
Next find how much 1% is.
Divide by 45.

Multiply by 100 to find how much the whole time is: 
The decimal version is: 82.2222222222...
Which simplifies to 82 minutes.
