Answer:
0.5.
Step-by-step explanation:
Substitute x = -3 into the guiven function:
= 2(-3) - 1/2(-3) + 5
= -6 + 1.5 + 5
= -4.5 + 5
= 0.5
1. A. 10,000
Explanation: 10^4 = 10,000
2. x = -12
Explanation: see photo
Plotting the 4 points and doing visual inspection will tell us if the quadrilateral is a parallelogram. We can also do analytical techniques which are to determine the slope and the distance between the points. Doing either of these two will give us
<span>B. Yes,TUVW quadrilateral s a parallelogram because there are two pairs of parallel sides.

Step-by-step explanation:
y=2x
y=-2x-4
2x+2x=-4 (grouping like terms)
4x=-4
x=-1
im sorry but im not sure what y is
The height of the tree is 60 meters.
Explanation:
Let the height of the tree be x. The tree casts a shadow of 
meters and the distance from the top of the tree to the end of the shadow is 
meters.
The sides of the triangle are attached in the image below:
Using pythagoras theorem,
Expanding, we get,
Solving the equation using the quadratic formula 
, we get,
Simplifying, we have,
Thus,
and 
where the value 
is not possible because substituting the value in results in negative solution. Which is not possible.
Hence, the value of x is 60.
Thus, The height of the tree is 60 meters.
