Answer:
<em>The slope would be</em><u><em> -1/2.
</em></u>
Step-by-step explanation:
Since, the midpoint of the segment joining the points P (0, -4) and B (8, 0),
<em>
= </em><u><em>( 4, -2 ),
</em></u>
Now, the slope of the line passes through the origin and the point ( 4, -2) is,
= <u>-1/2</u>

Answer:
x=58, m<DCB=56°
Step-by-step explanation:
Ok the sum of those two angles should equal 180 degrees so,
2x+8+x-2=180
solve the equation
3x+6=180
3x=174
x= 58
M<DCB=x-2--> 58-2=56

Answer:

Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= 
[ 2a₁ + (n - 1)d ]
where a₁ is the initial value and d the common difference
Given
= [ 10 + (n - 1)3 ]
Then by comparison
2a₁ = 10 ( divide both sides by 2 )
a₁ = 4 ← initial value
and d = 3 ← common difference
Thus
= 
[ 10 + (7 × 3) ]
= 4(10 + 21)
= 4 × 31
= 124
