8800
Step-by-step explanation:
Answer:
5 square units.
Step-by-step explanation:
See the attached graph where D, E, F, and G points are plotted.
So, in trapezium DEFG, the parallel sides are GF and DE.
Now, it is clear from the graph that, the length of segment GF = (3 - 1) = 2 units and the length of line segment DE = (3 - 0) = 3 units.
Now, the altitude of the trapezium is GD with length (4 - 2) = 2 units.
Therefore, the area of the trapezium will be given by
⇒ square units. (Answer)
Answer:
In the graph we can find two points, lets select:
(2, 15) and (4, 30)
Those are the first two points.
Now, for two pairs (x1, y1) (x2, y2)
The slope of the linear equation y = s*x + b that passes trough those points is:
s = (y2 - y1)/(x2 - x1)
So the slope for our equation is
s = (30 - 15)/(4 - 2) = 15/2
then our linear equation is
y = (15/2)*x + b
now we can find b by imposing that when x = 2, y must be 15 (for the first point we selected)
15 = (15/2)*2 + b = 15 + b
b = 15 - 15 = 0
then our equation is:
y = (15/2)*x
Where we used a division and a multiplication.
Answer:
y =2.5
Step-by-step explanation:
1.4y = 3.5
Divide each side by 1.4 to isolate y
1.4y /1.4 = 3.5/1.4
y =2.5
