Answer:
8+8/-8-4
16/-12
4/-3
8=4/-3(-8)+b
8*3=12+b
24=12+b
12=b
y=-4/3+12
Step-by-step explanation:
I think this helps, like a lot!
Y = -3x + 5
5x - 4y = -3
5x - 4(-3x + 5) = -3
5x + 4(3x) - 4(5) = -3
5x + 12x - 20 = -3
17x - 20 = -3
+ 20 + 20
17x = 17
17 17
x = 1
y = -3x + 5
y = -3(1) + 5
y = -3 + 5
y = 2
(x, y) = (1, 2)
4.85
<= x < 4.95 . does not intersect x > 5.No it
does not need to be sent to the lab. B.
<span>yes,
since the beaker meaures to the nearest tenth of a liter , the range of
the actual value is plus or minus 0.1 liters , which means there could
be up to 5 liters of the substance </span>
Answer:
A. 5b > 650 + 2.25b; B. 237 brownies
Step-by-step explanation:
A. Set up the inequality
Let b = the number of brownies. Then
Cost = 650 + 2.25b
Sales = 5b
Profit = Sales - Cost
To make a profit, we must have
Sales - Cost > 0 or
5b > 650 + 2.25b
2. Solve the inequality
3. Check
OK.
