Answer:
$12.89
Step-by-step explanation:
3.23 lb × 3.99 $/lb = 12.8877 $
Since we have to round to the nearest cent, Sanaa should collect $12.89.
Y=-2/3 x-2
y=-2x+2
We solved this equations system by equalization method.
-2/3 x -2=-2x+2
Least common multiple: 3
-2x-6=-6x+6
-2x+6x=6+6
4x=12
x=12/4=3
y=-2x+2
y=-2(3)+2=-6+2=-4
Solution: x=3; y=-4
To chek:
y=(-2/3)3-2=-4
y=-2(3)+2=-6+2=-4
The domain is the 1st number in the each pair.
So it’s like this (Domain, Range) hope this helps
Step-by-step explanation:
x, y = 2 numbers
x = 2y
y - x/2 = 20
this is impossible to solve. there is no solution.
because the first equation tells us
y = x/2
and so the second equation is
x/2 - x/2 = 20
0 = 20
so, again, no solution.
