(3,2)
Step-by-step explanation:
The solution that satisfies both equations is where the two lines intersects.
The two graphs intersect at x=3 and y =2
30 animals on Wednesday =
22 cats x $3.50 per day = $75
8 birds x $1.00 =$8
$75 + $8 = $85
# of birds @ the shelter = 8
# of cats @ the shelter = 22
Find slope: (y2-y1)/(x2-x1)
(6-3)/(-5-0) = 3/-5 = -3/5
Equation: y = -3/5x + b
Plug in a point
3 = -3/5(0) + b, b = 3
Solution: y = -3/5x + 3
Answer:
Step-by-step explanation:
Let the number of notes is x.
<u>20% of notes is: </u>
<u>40% of the remainder is: </u>
- 40% of 0.8x, so it is
- 0.8x*0.4 =
- 0.32x
<u>Remaining notes are:</u>
<u>Total of the notes:</u>
- 0.2x*10 + 0.32x*5 + 0.48x*2 = 1026
- 2x + 1.6x + 0.96x = 1026
- 4.56x = 1026
- x = 1026/4.56
- x = 225
