The answer would be letter D!
hope this helps!! pls also mark me brainliest if you can :)) i am trying to level up. thank you!!
<span>If there were 6 pieces total and Keith ate two of them.
So 6/6 - 2/6 = 4/6 or 2/3.</span>
Answer:
The solutions 
are 
and the x-intercepts of 
are 
Step-by-step explanation:
Finding the solutions to 
means finding the roots, a root is where the function is equal to zero.
The x-intercept is the point at which the graph crosses the x-axis. At this point, the y-coordinate is zero.
To find the roots you need to:
Rewrite the equation with 
and 
Solve by factoring
Using the Zero factor Theorem: if ab = 0 then a = 0 or b = 0 (or both a = 0 and b = 0)
The solutions to the quadratic equation are:
Substitute back , solve for x
Apply the difference of squares formula
Using the Zero factor Theorem: if ab = 0 then a = 0 or b = 0 (or both a = 0 and b = 0)
The solutions are:
Because two of the solutions are complex roots the only x-intercepts are
It is a function because every input has exactly one output. It passes the vertical line test.
If you plotted another point at 2 hours it would no longer be a function bc 2 would be an input they had more than one output.
Answer:
<h3>The answer is 60cm</h3>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
Area of rectangle = l × w
where
l is the length
w is the width
From the question
The length is twice its width is written as
l = 2w
Substitute this into the formula for finding the area of the rectangle
Area = 200 yd²
200 = 2w²
Divide both sides by 2
w² = 100
Find the square root of both sides
width = 10cm
Substitute this value into l = 2w
That's
l = 2(10)
length = 20cm
Perimeter of the rectangle is
2(20) + 2(10)
= 40 + 20
<h3>= 60cm</h3>
Hope this helps you
