Trapezoid Area = (Bases / 2) * Height
20 cm² = 5 * Height
Height = 4 cm
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes, so we can find the slope:

Thus, the equation is of the form:

We substitute one of the points and find "b":

Finally, the equation is of the form:

ANswer:

Answer:
h<-8/3
Step-by-step explanation:
collect like terms
-10h+7h>9-1
3h>8
divide both sides of the inequality by -3 and flip the inequality sign
h<-8/3
