Answer:
(-1, -2)
Step-by-step explanation:
Plug (x-1) for y in the first equation:
-4x + 3(x-1) = -2
Simplify:
-4x + 3x - 3 = -2
-x = 1
x = -1
Plug in x=-1 into the second equation:
y = (-1) - 1
y = -2
Aaron's sister Miriam has checking accounts in seven different banks.
They are all overdrawn.
All together, Miriam owes $35 to all 7 banks combined.
What is the average balance in each of Miriam's seven accounts ?
Answer:
A) 3500
Step-by-step explanation:
C(x) = 0.75x + 3500
C(x) = Total cost
0.75x = variable cost
3,500 = fixed cost
The fixed cost of the function = 3,500
Variable cost refers to cost of production that changes during production such as cost of raw material, wages of workers etc.
Fixed cost are cost of production that remains the same (does not change) with the production process such as building, machineries etc
Total cost is the addition of all cost of production, that is, the addition of fixed cost and variable cost
Answer:
The distance between the two piers is <u>3 miles.</u>
Step-by-step explanation:
If in Tasha's drawing 2cm represents 0.5 miles between the two piers, and the distance between the two piers in Tasha's drawing is 12cm.
The answer is found by <u>the rule of three:
</u>
2 cm : 0.5 miles
12 cm : X
X = (12 * 0.5) / 2
X = 3 miles.
The distance between the two piers is actually 3 miles.
Solution :
Since, we can measure the height of fluid. Let it be h.
So height of cylinder is double the height i.e. 2h because cylinder is partially filled.
Also, we can also measure diameter. Let it be d.
Now, we know, radius is haft the length of diameter.
So, r = d/2.
Volume of cylinder is given by :
Hence, this is the required solution.
