the answer is b. the rest is so it can be enough charecters so i can post this answer
Rearrange the formula so that its in the form of y=mx+b
so it would be:
8y= -4x + 4
then divide by 8:
y= -4/8 x + 4/8:
Simplify:
y= -1/2x + 1/2
the slope is -1/2
5) it is a function because each x value only has one y value. Domain: (-infinity,infinity) range: [0,infinity)
6) it is a function. Domain: (-infinity, infinity) Range: [3,3]
7) it is a function. Domain: (-infinity, infinity) range: (-infinity, infinity)
8) it is a function. Domain: [0, infinity) range: [0, infinity)
Answer:
C) 100 m^2
Step-by-step explanation:
Area of a trapezoid= h*[(b1+b2)/2]
h=10
b1=8
b2=12
Therefore:
A=10*[(8+12)/2]
A=10*(20/2)
A=10*10
A=100
So the area of the trapezoid is 100 m^2
