Answer:
They should insert that y value into the other equation.
Step-by-step explanation:
Answer:
50 minutes
Step-by-step explanation:
Use proportions
=
Solve for x
3x = 150
Divide by 3
x = 50 minutes
The correct answer would be 3 +/-
In order to solve for this you must first get the equation equal to 0.
x^2 + 6x + 9 - 6 ----> simplify like terms
x^2 + 6x + 3
Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.
a = 1 (because it is the coefficient to x^2)
b = 6 (because it is the coefficient to x)
c = 3 (because it is the end number)
Now we can plug these values into the quadratic equation.
3 +/-
And those would be your two answers.
The best choice is C, which represents the increases made by the tax and by the tip.
Answer:
Amount of water in bottle = 3/8 liter
Step-by-step explanation:
Given:
Total capacity of bottle = 3/4 liter
Amount of water in bottle = 1/2 of total capacity
Find:
Amount of water in bottle
Computation:
Amount of water in bottle = [Total capacity of bottle[1/2 of total capacity]
Amount of water in bottle = [3/4][1/2]
Amount of water in bottle = 3/ [(4)(2)]
Amount of water in bottle = 3/8 liter
