Answer:
Well, I am not sure which one is equivalent to another, but I have some information that should help you find your answer.
Step-by-step explanation:
The simplified expression to x2 − x − 6 x2 + 2x − 15 would be equal to −5 x 2 + x − 15.
The simplified expression to x + 3 x + 5 would be equal to 4x + 5.
The simplified expression to x + 2x + 5 would be equal to 3x + 5.
The simplified expression x + 3 x − 3 would be equal to 4x − 3.
The last simplified expression to x + 2 x − 3 would be equal to 3x − 3.
Hope this helps, I am really sorry if I didn't answer your question properly, or the way you asked!
In descriptive statistics, the interquartile range<span> (</span>IQR<span>), also called the midspread or middle 50%, or technically H-spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles... ~ wikipedia
according to Wikipedia and some quick mental math the answer would be four
four is the difference between 14 and 18 which are respectively the 25th and 75th percentiles.</span><span />
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)
That is impossible but I did some math so there are 2 ways that will equal more than 40.
6.7×6.0=40.2
6.5×6.2=40.3
Hope this helps!
