Answer:
3rd one
Step-by-step explanation:
The slope of line AB, BC, CD and AD are 1, -1/6, 2, -4/6 respectively. Quadrilateral ABCD with the given vertices is not a parallelogram because neither pair of opposite sides is parallel. Option C
<h3>How to determine the slope</h3>
Formula for slope is given as;
Slope =
A(-4 -1)
B(-1 2)
C(5 1)
D(1 -3)
a. Slope of line AB = = = = 1
b. Slope of line BC = =
c. Slope of line CD = = = 2
d. Slope of line AD = =
Quadrilateral ABCD with the given vertices is not a parallelogram because neither pair of opposite sides is parallel. Option C
Thus, the slope of line AB, BC, CD and AD are 1, -1/6, 2, -4/6 respectively.
and quadrilateral ABCD with the given vertices is not a parallelogram because neither pair of opposite sides is parallel. Option C

I have no idea but this answering thing gives me points sorry
Answer:
3.5
Step-by-step explanation:
5(6-x)=12.5
(5*6)-(5*x)=12.5
30-5x=12.5
subtract 30 from each side:
-5x=-17.5
divide -5 from each side:
x=3.5
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x -----> time of the first process in minutes
y -----> time of the second process in minutes
we know that
The time of the first process multiplied by 4 (because is repeated 4 times) plus the time of the second process multiplied by 1 (because is repeated only once) must be less than or equal to 3 minutes
so
The inequality that represent this situation is
The solution of the inequality is the shaded area below the solid line
The equation of the solid line is
The y-intercept of the solid line is the point (0,3)
The x-intercept of the solid line is the point (0.75,0)
The slope of the solid line is negative m=-4
using a graphing tool
The solution is the shaded area
The graph in the attached figure
Remember that the time cannot be a negative number
