Answer:
5x+6y=60
Step-by-step explanation:
x= $5 per pound of second type of seed
y=$6 per pound of first types of seed
In y = mx + b form, the slope can be found in the m position and the y intercept can be found in the b position.
y = mx + b
y = 2x + 15
slope(m) = 2 and y int (b) = 15
The initial amount is the y intercept, which is 15. The rate of change (the slope) is 2
example :
baskets picked in 1 hr :
y = 2(1) + 15
y = 2 + 15
y = 17
baskets picked in 2 hrs :
y = 2(2) + 15
y = 4 + 15
y = 19
so the slope ( rate of change) is basically saying for every hr of picking, you pick 2 baskets...so your picking 2 baskets per hr.
The y intercept (15) is telling us that they already had 15 baskets to start with.

Step-by-step explanation:
×7 = 
Answer:
Alloy = 12.6 lbs.
Step-by-step explanation:
( 2/7 ) = ( Nickel /4.9)
Nickel = 1.4 lbs.
Ratio of Copper to Zinc:
( 9/7 ) = ( Copper /4.9)
Copper = 6.3 lbs.
Alloy = Zinc + Nickel + Copper
Alloy = 4.9 lbs. + 1.4 lbs. + 6.3 lbs.
Alloy = 12.6 lbs.
