Word the problem so it helps you with the double number line like this:
Question:
If 1/6 mile of a fence is completed each hour how long will it be in 4 hours?
Then use the double line:
1/6-----miles(1/6*4)------X Length X=1/6*4
I X= 1/6*4/1
I X= 4/6 ≈2/3 miles
1-------hours--------------4 Time
Here is a video that might help with your homework a lot :) Good luck

Determinant = b² - 4ac = (-10)² + 4*1*25 = 100 - 100 = 0
So it has 1 solution.
Answer is D
Answer:
x = 3
Step-by-step explanation:
We are given a vertical line which means that the slope is undefined. Since we are passing through the x-axis at (3, 0) with no y-intercept, we will write this as x = 3.
Best of Luck!
Answer:
<h2>
666.67</h2>
Step-by-step explanation:
Multiply 120x50 and then divide that answer by 9 since we are calculating the <u>square yards</u>
First get the equation into the form: Ax^2 + Bx + C = 0 (the quadratic equation)..
We do this by subtracting 10x both sides (to get it on the other side)..
9x^2 + 2 = 10x
9x^2 - 10x + 2 = 10x - 10x
9x^2 - 10x + 2 = 0
Now the discriminant is: b^2 - 4ac
The quadratic equation is Ax^2 + Bx + C = 0
Here, A = 9, B = -10 and C = 2 so plug them in...
(-10)^2 - 4 (9)(2)
= 100 - 4 (18)
= 100 - 72
= 28 <--- answer...
