Its simple, so these are two "y=mx+b" form lines that are limited by the signs on the right. Your first line f(x)=-x-4 has to be between -3 and 1 on the x-axis.
You would plot a point at (0,-4) like normal, then go down one, right one as the slope is -1. you would make the dot at 1 though unfilled as x does not equal to 1. It is less than 1. º Should look like the dot I just inserted.
The second line would be plotted, at (0,-6). You would then make a horizontal line between 1 and 5. º-------• (Should look like this)
IMPORTANT:
FILLED DOT - EQUAL TO
UNFILLED DOT - Not equal to
Let mass of truck be t
mass of car A be a
and carB be b
so , a=2b-5
t=a+2135
putting a into t...
t=2b-5+2135
so, a+b+t=11350 ( putting all values)
2b-5+b+2b-5+2135=11350
so b=1845
a=3685
t=5820
so weight of Car A is 3685 lb
weight of Car B is 1845 lb
and truck is 5820 lb ......answers !!
1.Rita spent $26.25 on fabric.
2. I know this because...
- First, I subtracted the cost of the ribbon from how much she paid.
· Equation: $50.00 - $18.50 = $31.50
- Second, I subtracted the change received by the reduced cost ($31.50)
· Equation: $31.50 - $5.25 = $26.25
3. So, the final amount of money Rita spent on fabric is $26.25.
