The answer is a. You find the area of each shape and add them
Answer:
v > -6
Step-by-step explanation:
2*v-(-12)>0
Pulling out like terms :
1.1 Pull out like factors :
2v + 12 = 2 • (v + 6)
Equation at the end of step 1 :
Step 2 :
2.1 Divide both sides by 2
Solve Basic Inequality :
2.2 Subtract 6 from both sides
v > -6

2.3 Inequality plot for
2.000 X + 12.000 > 0
Another way to solve this is to use the Midpoint Formula. The midpoint of a segment joining points
and
is
So the midpoint of your segment is
Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points. Ditto for the y-coordinate of the midpoint; just average the y's.
Answer:
1). Corresponding angles
2). Vertical angles
Step-by-step explanation:
1). Lines 'k' and 'l' are the parallel lines and line 'm' is a transverse.
Since m∠ABC = 19°
Therefore, m∠ECF = 19° [Corresponding angles]
(By translating line 'l' from the points B to C, angle ABC overlaps angle ECF)
2). Since, ∠ECF and ∠BCD are the vertical angles they will be equal in measure.
Therefore, m∠ECF = m∠BCD = 19°
