Answer:
Tip Total: $ 11
Total (Bill + Tip): $ 62
Step-by-step explanation:
|2x-3|=2x-1
need to consider two cases
(1) 2x-3<0 --> x<3/2
-(2x-3)=2x-1
x=1, and this is <3/2 so that's a valid solution
(2) 2x-3>=0 --> x>=3/2
2x-3=2x-1
-3 = -1 so there no solution for x>=3/2
The single solution is x=-1
0.6 I think that’s what you’re asking
The first term is -5, the 50th term is -5-2*49=-103
The sum is the average of these terms times number of terms, which is (-5-103)/2*50=-2700
Y=mx+b
m=slope
b=y intercept or where the line crosses the y axis
slope=rise/run, from left to right
so
1.
ok, so we see it is going throught (-2,1) and (-1,4)
so it hits (-2,1) and then goes up 3 and right 1
so sloe=3/1 or 3
y intercept, it hits at y=7 so
y=3x+7 is equation
2.
we gots a hit at (0,2) and (5,6) about
so goes up 4 and to the right 3 so
4/3 is slope
hits y axis at about y=2
y=(4/3)x+2
