W=8
k=2
-9(-3k+6w)
-9(-3(2)+6(8)
-9(-6+48)
-9(42)
-378
The answer is -378
7.86 x 4 is 36.156 because you have to line up the decimals and multiply them and then you get 36.156
First find the slope of the line connecting these two points:
6-5
m = ------------ = -1/2
-4+2
Substitute this slope into y = mx + b: y = (-1/2)x + b.
Next, subst. 5 for y and -2 for x, and find b:
5 = (-1/2)(-2) + b, or 5-1=b. Then b = 4, and
the equation of the line is y = (-1/2)x + 4.
I only see the store question but the answer is correct, 600
The unit rate is 30/1 since there’s 180 gallons in 6 minutes there is 30 in 1. i’m not sure what the origin really represents other than the starting point. do you need help with the graphing too ?
