Scale 1:2 means that 1 cm on the drawing is 2 cm in reality. So the square is 8cm x 8cm = 64cm².
Notice that while the size gets two times as big, the area gets 2²=4 times as big. That can be confusing. If you actually draw the square on 1:1 and also on 1:2, you can easily see that the latter fits 4 times in the real size...
Answer:
8 + 4i
Step-by-step explanation:
Put corresponding terms above each other and subtract in the usual way.
z = 3 + 5i
<u> w = -5 + i
</u>
z - w = 8 + 4i: 3 - (-5} = 8; 5i - 1i = 4
i
Answer:
rise is 20 and run is 5 so slope is 4.
I think the slope y-intercept is -5
Answer:
Table W represents a function
Step-by-step explanation:
Mathematically, for us to have a function , no two y-values can take a single x value
But it is possible that two x-values have a single y value
So let us make a selection from the table
We have the correct option as;
W
Answer:
( 1, - 3.5 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) the midpoint is
( , )
Here (x₁, y₁ ) = C (9, 2) and (x₂, y₂ ) = D (- 7, - 9 )
midpoint = ( , ) = ( , ) = (1, - 3.5 )
