Answer:
Where is the diagram
Step-by-step explanation:
?????
Answer:
A) reflection across the y-axis
Step-by-step explanation:
If 
, then this says that two 
-coordinates are equal for opposite values of 
.
Let 
a point on 
.
Then 
.
We also know that 
and therefore 
is also a point on the graph.
If you graph [/tex](-a,b)[/tex] and you will see they are symmetrical to each about the -axis.
Example if given both and 
, then 
. This means both (2,3) and (-2,3) are points on the graph.
Here is what those two points look like on a Cartesian Plane (please see graph in picture).
The formula for area of a trapezoid is: 1/2 (b1+b2) h
b1=10
b2=10·2=20 because it stated the side parallel is twice as long as the side above
h=10/2=5 because the height is half as long as the give side length
area of the trapezoid is: 1/2 (10+20) 5
(5·10)·5
50·5
area of the trapezoid is 250 in²
Answer:
12.5 km.
Step-by-step explanation:
Distance = average speed x time = 25 km/h x 0.5 h = 12.5 km.
if wrong, sorry
(but most likely right)
