Answer:
y = 17/7
Step-by-step explanation:
When x = 1
5(1) = -y + 6
5 = -y + 6
y = 6 - 5 = 1
When x = 2
5(2) = -y + 6
10 = -y + 6
y = 6 - 10 = -4
When x = 3
5(3) = -y + 6
15 = -y + 6
y = 6 - 15 = -9
The formula is 1/2 x ( a + b ) x h
A and b are the top and bottom sides and h is always the perpendicular height.
Now replace the variables...
1/2 x (6 + 14 ) x 8.4
And then...
1/2 x 20 x 8.4 which will give you 84cm^2
Hope this helps! Anymore questions let me know :)
The reason for that is if u were to make 4/6 and 2/10 have the same denominator which would be 40/60 and 12/60 40 is greater than 12 and that fraction is equivalent to 4/6
Answer:
From x = 0 to 3, f(x) = x^2.
From x = 3 to 6, f(x) = -x + 10
From x = 6 to 10, f(x) = x - 2
Step-by-step explanation:
The first part of the graph is a parabola that opens up with vertex at (0, 0). We check a few points, such as (0, 0), (1, 1), (2, 4), and (3, 9). The graph is f(x) = x^2.
The second part of a graph is a straight line with negative slope. The slope is -1. Prolong the line to the y-axis to get a y-intercept of 10. The equation is f(x) = -x + 10.
The third part of a graph is a straight line with positive slope. The slope is 1. Prolong the line to the y-axis to get a y-intercept of -2. The equation is f(x) = x - 2.
From x = 0 to 3, f(x) = x^2.
From x = 3 to 6, f(x) = -x + 10
From x = 6 to 10, f(x) = x - 2
