Answer:
-10
Step-by-step explanation:
Find the slope:
5-0/3-2=5
y=5x+b
substitute and ordered pair for x and y
5=5(3)+b
solve for b
b=-10
Only a immature fool would laugh at someone asking for help.
see how x goes up one (the top one)
y goes up? 0.8
so the next is 6.2 and 7.0

Answer:
The scientist must use 10 ounces of Solution A and 40 ounces of Solution B.
Step-by-step explanation:
Since a scientist has two solutions, which she has labeled Solution A and Solution B, each containing salt, and she knows that Solution A is 40% salt and Solution B is 90% salt, and she wants to obtain 50 ounces of a mixture that is 80% salt, to determine how many ounces of each solution should she use the following calculation must be performed:
100 x 0.9 + 0 x 0.4 = 90
90 x 0.9 + 10 x 0.4 = 85
80 x 0.9 + 20 x 0.4 = 80
50 x 0.8 = 40
Therefore, the scientist must use 10 ounces of Solution A and 40 ounces of Solution B.
