7 because 7 • 7 = 49 • 7 = 343
The reflection of the point (x,y) across the x-axis is the point (x,-y), so take the coordinates of each point and change them accordingly then graph them.
Answer:
The value of a=6[/tex]
Step-by-step explanation:
<u>step 1:- </u>
<u>col linearity of three points :- </u>
We know that slopes of two parallel lines are equal.If two lines having the same slope pass through a common point ,then two lines will coincide . Hence ,If A,B,C are three points in the X Y- plane, then they will lie on a line,
that is three points are col linear if and only if Slope of AB= slope of BC
<u>step 2:-</u>
Since the given three points are col-linear, we have
Slope of AB= slope of BC
given points are A(2,-2) ,B(-6,2) and C(a,-4)
<u>Step 3 :-</u>
Slope of AB= slope of BC


200 is 1/10 of 2,000.
because it is 1/10 you times it by ten.
200×10= 2,000
