Answer:
mai is faster
Step-by-step explanation:
because even though she on goes 15 meters in 6 seconds she would have 4 times the advantage because of the extra 4 seconds she has
The simple way to dilate from the origin is to multiply each coordinate by the dilation factor.
Example:
point A(2,-4) dilated by 2
A'(2*2, -4*2) = A'(4, -8)
Point A dilated by 1/2
A''(2*1/2, -4*1/2) = A''(1, -2)
If you have multiple points dilated by the same factor, then follow the procedure for ALL the points
So,...
the slope intercept form is y = mx+b
the m is the slope, and the b is the coordinate that intercepts the y-axis
so to start you off, 4x - 9y = 2
4x - 9y = 2
-4x - 4y
-9y = -4y +2
divide both sides by -9
<u>-9y </u>= <u>-4y + 2</u>
-9 -9
y = 4/9 x - 2/9
26/5 is 5.2 as a fraction
