(5x² - 3x + 5) - (3x² - 4x - 7) Distribute/multiply - into (3x² - 4x - 7)
5x² - 3x + 5 - 3x² + 4x + 7 Combine like terms
2x² + x + 12
The answer is A
Point slope form is:
y -

= m(x -

)
With

and

being the coordinate points, and m being the slope.
So the coordinate points are (4, -5), and the slope is -6 in this case.
So just substitute everything in, to get:
y - ( -5) = -6(x - 4)
Or
y + 5 = -6 (x - 4)
It means 25 divided by 0.2
Guven that the <span>distance
d that a certain particle moves may be calculated from the expression

where a and b are constants; and t is the elapsed time.
Distance is a length and hence the dimension of distance is L.
Now,

and

also will have the dimension of L.
</span><span>Time has a dimension of T.
For

, let the dimension of

be

, then

For

, let the dimension of

be

, then

Therefore, the dimension of

is

while the dimension of

is
