Step-by-step explanation:
I’m not 100% sure but isn’t it x2 +xy +y2?
The mean would be 4.5. This is because you add up all the numbers which equals 22.5. Then divide by 5 since there is 5 numbers in the set. So the answer comes out to be 4.5.
Answer:
3x×1/3=9×1/3
x=3
Step-by-step explanation:
fill it in
reciprocal of 3 = 1/3
When the dilation of a line or is centered at the origin,
both the x and y coordinates are multiplied by the same value, k (which
represents the scale or ratio of dilation)
If ab is dilated by a factor of 2/5 to produce a’b’, then k
= 2/5
Since the dilation is centered at origin,
The y-coordinate of b' what will be 2/5 of the y-coordinate of b.
