Y = 2x + 3 - it's a linear function
for x = 0 → y = 2 · 0 + 3 = 3 ⇒ A(0; 3)
for x = -2 → y = 2 · (-2) + 3 = -4 + 3 = -1 ⇒ B(-2;-1)
Look at the picture.
First find the common denominator
5/8=25/40
2/5=16/40
3/4=30/40
Next you can cross multiply
25/40=x/10 pounds
16/40=x/10 pounds
30/40=x/10 pounds
First
25(10)/40= 6.25 pounds
16(10)/40= 4pounds
30(10)/40= 7.5 pounds
These are the amounts that were left in the bag
10-6.25=3.75
10-4=6
10-7.5=2.5
3.75+6+2.5= 12.25
All together they put 12.25 pounds of soil in the flower bed
