Answer:</h3>
y = -3x +2
<h3>
Step-by-step explanation:</h3>
The y-intercept is at +2, so that is the value of the added constant (b).
The line goes down 3 units for each unit to the right, so the slope (m) is ...
... m = ∆y/∆x = -3/1 = -3
Then in the form ...
... y = mx + b
with m=-3 and b=2, your line's equation is ...
... y = -3x +2

Answer:
When 2 people work together the total time equals
Total Time = Time 1 * Time 2 / (Time 1 + Time 2)
Let's solve for Time 1 (which will be Tim's time.)
7 hours = Time 1 * 9 / (Time 1 + 9)
7 * Time 1 + 63 = Time 1 * 9
63 = 2 * Time 1
Time 1 = 30.5 Hours (Tim's Time)
Double Check
Total = 30.5 * 9 / (30.5 + 9)
Total = 274.5 / 39.5
Total = 7 Hours
Again, Tim's Time is 30.5 Hours
Step-by-step explanation:
To be a function, for any X value( input) you can only have one Y(output value).
In A) there are two x values of 2, but each one has a different Y value, so this cannot be a function.
In C, there are two x values of 1, each with a different Y value, so also cannot be a function.
D) has two X values of 0, and each has a different Y value so cannot be a function.
The correct answer would be B.
Answer:
$1.00
Step-by-step explanation:
Dimes = 10 / Nickels = 5 / Quarters = 25
6(10) + 3(5) + 1(25)
60 + 15 + 25 = 100 so that makes it $1.00
