We have two coordinates here: (2, 225) & (5, 480)
Now, Calculate for the Slope:
m = y2-y1 / x2-x1
m = 480-225 / 5-2
m = 255/3
m = 85
y - y1 = m(x - x1)
y - 225 = 85(x - 2)
y - 225 = 85x - 170
y = 85x + 55
8x - y = -55 [ Final Equation in the standard form ]
B.) F(x) = 85x + 55
C.) For x=1, F(x) = 85(1) + 55 = 140
For x = 2, F(x) = 85(2) + 55 = 225
For x = 3, F(x) = 85(3) + 55 = 310
In short, Your Coordinates for the Graph would be: (1, 140) (2, 225), (3, 310)...
Hope this helps!
Answer:
Step-by-step explanation:
The permiter of a rectangle got be determined by the following equation:
P = 2L + 2W
where P is the perimeter, L is the length of the rectangle, and W is the width of the rectangle.
From the problem statement, we know that P = 60, and that the length is twice the width, so we have the following two equations:
60 = 2L + 2W
L = 2W
If we substitute the second equation into the first, we have the following:
60 = 2(2W) + 2W
60 = 4W + 2W
60 = 6W
10 = W
Plugging this value back into the second equation, we have the following:
L = 2W
L = 2(10)
L = 20
The area of a rectangle is determined by the following:
A = LW
where A is the area.
Plugging in the values that we determined previously we give you the answer.
Answer:
6 23/70
Step-by-step explanation:
2 9/10 + 3 3/7 = 2 + 63/70 + 3 + 30/70 = 5 + 93/70 = 5 + 70/70 + 23/70 =
= 5 + 1 + 23/70 = 6 + 23/70 = 6 23/50
Answer:
$371.25
Step-by-step explanation:
If you want to take away 25%, you would need to find out how much 75% of the current price is. IF you think about it, 75% of the $495 is 25% of 100% of it taken away.
So
0.75 x 495 = 371.25
