Answer:
8 + .21 = 8.21
8 - .21 = 7.79
Step-by-step explanation:
Y = 8x - 2.....slope here is 8. A parallel line will have the same slope.
The other line would be : y = 4 + 8x (or y = 8x + 4).....because they both have the same slope, which makes the lines parallel to each other
Using pythagoras length of the other leg = sqrt ( 8^2 - 4^2) = sqrt 48 = 4 sqrt3
the ratio of the sides of the triangle = 8 : 4 :4 sqrt3 = 2:1:sqrt3 so this is a
30-60-90 degree triangle
I think the answer is A 28,4 I hopes this helps
Answer:
A
Step-by-step explanation:
Slopes for everything is Rise/Run or change in Y/ Change in X
Slope of A = 2x since its twice of x
Slope of B = 1/2 since its 5-4/4-2
Slope of C = 5/2
Slope of D = 3/2
Biggest slope is A
