Y = 2x^2 - 4x + 2
y = 2(x^2 - 2x + 1)
2(x - 1)^2 = = 0
so the graph will just touch the x axis at x = 1
So there is one zero duplicity 2.
Answer:
The length of diagonal is 4.922 feet.
Step-by-step explanation:
Let the width be = w
Let the diagonal be = d
Let the length be = l
Given is that the diagonal measures three times the width, this gives: 
Also given is the length of the plywood is three feet more than the width. This is : 
Now, in terms of x we get:
Width = x
Length = (x+3)
Length of Diagonal = 3x
Now applying Pythagorean Theorem



Solving this we get,
We will use quadratic formula to solve this and get the answer,
x = 3/7 +/- (12√2) / -14
x = 1.64075 or x = -0.783612(neglect this negative value)
So, x = 1.64075 feet
Now length of diagonal is 3x = 3*1.64075 = 4.922 feet
So, length of diagonal is 4.922 feet.
Answer:
it would be six square yards or add all the numbers and your total will be it
Step-by-step explanation:
Answer: -x + 4y
Step-by-step explanation:
-3(2x-y) + 2y+2(x+y)
-6x + 3y + 2y + 2x + 2y
-6x + 2x +3y + 2y + 2y
-6x + 5x + 4y
-x + 4y
Answer: 3
Step-by-step explanation:
The y intercept is where the line intercepts the y, or vertical axis.
In this case, the line and y axis intercept at 3.
Hope this helps!
