Answer:
Sum means to ADD in the math world
Step-by-step explanation:
So your answer would be d + 9
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:
If you were trying to find 15% of 18, that would be multiplying a decimal, but, you need to mutliply a whole number. $120 should be your answer. People, correct me if I'm wrong (seriously though, not 100% sure if this is correct).
Step-by-step explanation:
18 = 15% x Y
18 = 15/100 x Y
Y = 18 × 100/15
Y = 18 × 100 ÷ 15
Y = 120
Answer:
23/7 or 3 2/7
Step-by-step explanation:
it might be the mixed number
Answer:
The skaters will collide at the points;
(2,28) and (4,24)
Step-by-step explanation:
The points they might collide will be the points when both y are equal;
-2x + 32 = -2x^2 + 18x
2x^2 -18x -2x + 32 = 0
2x^2 -20x + 32 = 0
2x^2 - 16x - 4x + 32 = 0
2x(x -8) -4( x -8) = 0
(2x -4)(x -8) = 0
2x = 4 or x = 8
x = 4/2 or x = 8
hence; x = 2 or 8
Now let’s get the y value
at x = 2, just substitute into any of the 2
y = -2x + 32
y = -2(2) + 32
y = -4 + 32 = 28
at x = 4
y = -2(4) + 32
y = -8 + 32
y = 24
The points that they will collide are;
(2,28) and (4,24)
