Answer:
Solid Line, Shade Above
Explanation:
Given:
The second inequality in the system is:
The intercepts of the boundary line (y=x-4) are (0, -4) and (4,0).
Since the inequality has an equal to sign attached, we use a solid line.
At (0,0)
Since the inequality 0≥-4 is true, shade the side that contains (0, 0) as shown in the graph below:
So, we use a solid line and shade above the boundary line.
Answer:
Capacity of old tank = 1650 barrels.
Capacity of new tank = 2000 barrels.
Explanation:
Let a be the capacity of old tank and b be the capacity of new tank.
A company added a new oil tank that holds 350 barrels of oil more than its old oil tank.
So we have b - a = 350 ----------------------equation 1
Together they hold 3650 barrels of oil
a + b = 3650 ----------------------equation 2
equation 1 + equation 2
2b = 3650 + 350 = 4000
b = 2000 barrels.
Substituting in equation 1
2000 - a = 350
a = 1650 barrels.
Capacity of old tank = 1650 barrels.
Capacity of new tank = 2000 barrels.
The answer is 47 minutes.
You basically imagine this: Debra has a phone card for $30. She used x minutes every 16 cents. You end up with $22.48.
30 - (0.16x) = 22.48
You can basically graph that equation and the x-intercept will show you your answer. x = 47
Answer:
a^2 - b^2 = (a+b)(a-b) where a = X and b = 6
(X+6)(X-6)

Step-by-step explanation:
Answer:
C. 0.492
Step-by-step explanation:
All I did was add the two numbers. Add them like normal, even though they are in decimal form. You could also use a calculator. If you don't have one, there should be one programed into your phone and computer.
0.467
+ 0.025
= 0.492
