Is y=-2/3x+1 and y=-3/2+5/2 perpendicular

No

Step-by-step explanation:

For the two lines to be perpendicular, the product of their slopes must be -1.

Here, the product is

... (-2/3)×(-3/2) = 6/6 = 1 ≠ -1

so, the lines are not perpendicuar.

_____

They are reflections of each other across the diagonal line y=x-2.

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
