Answer:
9/25
Step-by-step explanation:
C. SSS is when all three sides are congruent
Direct variation: y=kx where k is some number thats not 0
that means if x is 2, y is 2k. if x is 1, y is k. if x is 0, y is 0.
notice: no matter what k is, when you put 0 in for x, y will always be 0. that means that a direct variation always goes through the origin, a.k.a. (0,0).
do all lines go through the origin? nah. a line is y=mx+b, where m and b are some numbers. a line is only a direct variation if b is 0. this makes sense because if b is 0, then the y-intercept is 0, so the line goes through the origin.
in conclusion, no, not all linear relationships are direct varations, but all direct variations are linear relationships.
The sub is at 1320 ft below sea level and must get to 180 ft below sea level
do 180 - 1320.
it comes out to 1140.
Which means, the sub must travel 1140 feet.
Must travel 19 feet per minute to do 1140 feet in 60 minutes.
Answer:
if you can provide the figure it would be quite easy for the people giving answers
