Answer: The system of equations represents the constraints in this situation are:
s + h = 40
$18s + $14h = $700
The above equations are known as simultaneous equations. 40 scarves and hats were sold, this can be represented with this equation:
number of hats sold + number of scarves sold = 40
s + h = 40
The total amount made from the sales is the sum of the total amount made from the sale of the hats and the total amount made from the sale of the scarves. This can be represented with this equation:
($18 x s) + ($14 x h) = $700
Step-by-step explanation:
Answer:
y = –x + 3
Step-by-step explanation:
I got right on ed.
A) it represents trough fill rate. It basically states after 8 minutes, the water level raised 28 cm.
B) for every 1 minute of pouring, the water level rises 3.5 centimeters.
C) if you look at those points as proportions
6/21 = 1/3.5
Or 8/28 = 1/3.5
They both can be proportionate.
Answer:
The red one/bottom one. x>-8
Step-by-step explanation:
Subtract 7 giving you 16. Divide by negative 2 which gives you -8, but since your dividing by a negative you have to flip the sign. The Answer is x>-8. The Sign points which way you have to shade, the answer is which point you shade at, and the opened circle means that it is NOT equal to that answer but it is bigger. Closed circle if it is equal to. ;)
