Answer:
i cant tell you the answer but one dot go to -1 and other one go to 5 then keep dotting
Step-by-step explanation:
use a ruler or ask your teachee
There's no way to tell with the given information.
You've given us one point on a graph . . . (-15, 12) .
There are an infinite number of different lines that can
go through that point. We don't know anything about
the function (how 'y' depends on 'x'), so we have no way
to know any other point on the graph.
Meet in 2 hours
means that the distance covered over 2 hours adds to total distance which is 13miles
basically, imagine instead of moving in oposite directions, toward each other, imagine that one moves for 2 hours then theh other one moves for another 2 hours, total 13 miles
so
speed1=x
speed2=y
x is 2.1 more than y
x=2.1+y
distance=speed times time
time=2hours
speed=x and y
total distance=13
13=2x+2y
x=2.1+y
sub
13=2(2.1+y)+2y
13=4.2+2y+2y
13=4.2+4y
minus 4.2 from both sides
8.8=4y
divide both sides by 4
2.2=y
sub
x=2.1+y
x=2.1+2.2
x=4.3
the hikers hiked 2.2mph and 4.3mph

Answer: -x + 2
Step-by-step explanation:
So I assume that the question would be set up like this if you are finding the sum of all 3 terms:
(x + 5) + (-4x - 2) + (2x - 1)
1) Take out parentheses
x + 5 - 4x - 2 + 2x - 1
2) Add like terms
For the x terms:
x - 4x = -3x
-3x + 2x = -x
For the other terms:
5 - 2 = 3
3 - 1 = 2
The sum of the terms is <u>-x + 2</u>
