0.8 squares shaded out of 10
You just do 4x2 which is 8
Then add the 0. In front of 8
Easy as that
Answer:
The answer is below
Step-by-step explanation:
A drink is made by adding water to juice.
Instructions
Add an amount of water that is between 3 times and 5 times the amount of juice
Tanya has 130 ml of juice.
If she follows the instructions, work out the minimum and maximum amounts
of the drink she can make.
Solution:
The minimum amount of water that can be added to the juice is 3 times the amount of the juice, hence:
Minimum amount of water = 3 * 130 ml of juice = 390 ml of water
Therefore minimum amount of drink = 390 ml of water + 130 ml of juice
minimum amount of drink = 520 ml
The maximum amount of water that can be added to the juice is 5 times the amount of the juice, hence:
Maximum amount of water = 5 * 130 ml of juice = 650 ml of water
Therefore maximum amount of drink = 650 ml of water + 130 ml of juice
Maximum amount of drink = 780 ml
The EASIEST way to do it, is actually start with the form a(x-b)(x-c) or intercept form since you have intercepts
x ints at (0,0) and (4,0) so y=ax(x-4)
sub in (2,-4) it doesn't really matter whether or not its a vertex
-4=2a(2-4)
a=1
so y=x(x-4)
expand to get y=x^2-4x which is y=ax^2+bx+c form where a=1, b=-4, c=0
First, let us translate the problem into an equation.
x²-27=6x
Then we can find its roots.
x²-6x-27=0
(x-9)(x+3)=0
x=9, -3
answer: -3
