Two sailboats are traveling along the same path away from a dock, beginning from different locations at the
same time. John's boat begins 30 miles from the dock and
is 50 miles from the dock after 5 hours. The distance of
Roberta's boat from the dock is represented by the
function y=
5x + 25, where x represents time and y
represents the distance from the dock.
Which boat was farther from the dock at the beginning, and which traveled
more quickly?

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

b.   e = 7.5h

hope this , lovely!

all of them are elements inside set of real numbers since none of them appears to have complex number form.

hope this .
