Answer:
-3/4
Step-by-step explanation:
Get the coordinates of the two points and use the slope formula to find the slope.
We'll call the points point A and point B.
Point A's coordinates are (-3,1) and point B's coordinates are (1,-2)
Now, plug the numbers into the slope formula
Slope formula is: y2-y1/x2-x1
-2-1/1--3
-3/4
Answer: y = -9x - 9
First, you need to put the two equations into slope intercept form (y=mx+b.)
1) y= -9x + 9
2) y= -10x - 9
First take the slope of #1
m = -9x
Then take the y-intercept of #2
b = -9
Now, put it into an equation.
y = -9x - 9
Answer:
x = 2
Step-by-step explanation:
A = lw
44 = 4(3x+5)
44 = 12x + 20
24 = 12x
x = 2
Answer: Its A Im pretty sure
Step-by-step explanation:
The truck cover 80 km per 1 hour that is 80 km per 60 min.
For half the time, the truck will cover half the distance.
So, for 30 min (half of 60 min) the truck will travel 40 km (half of 80).
In general, we could have done the following:
The truck travels
80 km per 60 min, so:
80/60 km per 60/60 min
that is
4/3 km per 1 minute.
in 30 minutes, the truck will cover a distance of (4/3)*30=4*10=40 (min)
Answer: 40 min
