Answer:
y = 1/2x
Step-by-step explanation:
Perpendicular slope is opposite and reciprocal
Answer:
F:53cm by 102cm
Step-by-step explanation:
The perimeter of a rectangle can be seen as 2l + 2w, with the length being l, and the width being d. If the ratio is 3:2, then 3+2= 5 parts would be the sum of the length and the width, This is half of the perimeter 2(l+w), so 510÷2 = 255. One part would be 255÷5=51.
If you put it into the ratio, effectively it is:
Length:Width
3×51:2×51
153 :102
Therefore the dimensions are 153cm by 102cm, which is F.
M²+8m+16=45
m²+8m-29=0
D=64+4*29=180
m₁=(-8+√180)/2=2.7
m₂=(-8-√180)/2=-10.7
m₁=2.7
m₂=-10.7
Hope this helps with the answer to your question
