Answer:
A
Step-by-step explanation:
The y intercept is simply where the line intercepts the y intercept in this case it's (0,2)
An easy way to slope is rise over run.
Simply find a point on the graph and count how many times you have to go up,down,left, or right to get to the next point
in this case it's 3
Since the slope is going down we know it will be negative.
1:3 = 16/48 and 1/3.
Have a nice day! :D
Answer:ooooooooooooooooooooooooooooooooooooooooooof
Step-by-step explanation:
Knowing that cos(45°) = 1/√2 is the way forward.
The last step in the equation may not be obious, but the trick here is to multiple numerator and denominator with (1-√2), then the denominator has the special product (a+b)(a-b) = a²-b².
Answer:
number of $20 bill = 4
Number of $5 bill = 5
Step-by-step explanation:
Given that:
Total number of $5 and $20 bills = 9
Let :
Number of $5 bills = x
Number of $20 bills = y
Combined worth of all bills = $105
x + y = 9 - - - (1)
5x + 20y = 105 - - - (2)
From (1)
x = 9 - y
Substitute x = 9 - y into (2)
5(9 - y) + 20y = 105
45 - 5y + 20y = 105
15y = 105 - 45
15y = 60
y = 60/15
y = 4
x = 9 - y
x = 9 - 4 = 5
Hence,
number of $20 bill = 4
Number of $5 bill = 5
