Hello from MrBillDoesMath!
Answer:
y = (1/8)x + 5
Discussion:
The slope (m) of y = -8x +4 is -8. The slope of the perpendicular lines is the negative reciprocal of the slope of the first line. That is, the perpendicular slope is -1 /(-8) = + 1/8
y = (1/8) x + b (*)
Also, the perpendicular line passes through the point (0.5) so substituting these values in (*) gives
5 = (1/8)(0) + b => as (1/8) 0 = 0
5 = b
The perpendicular line is given by y = (1/8)x + 5
Thank you,
MrB
The answer is C) 11/20<4/7
For this case we have that if each package of pencils has 10 pencils we have:
Thus, we have a total of 90 pencils.
If Peter lost 18 pencils we have:
Thus, Peter has 72 pencils left.
Answer:
After losing 18 pencils, Peter has 72 pencils left.
