<em>We can also graph inequalities on the number line. The following graph represents the inequality x≤2 . The dark line represents all the numbers that satisfy x≤2 . If we pick any number on the dark line and plug it in for x, the inequality will be true.</em>
Answer:
16
Step-by-step explanation:
as an expression: (15 - 6) + (-2 + 9)
simplify quantities: (9) + (7)
sum: 16
:D
It states your "X" will be zero when solving for "Y".
So when solving for "Y" your equation would be;
0+y=4
Then you solve. Y=4
Then you do the same with the "X":
X+0=4. Then you solve. X=4
It would end up being (4(x),4(y) )
Then do the same for the next problem.
Answer:
20m/h is equal to 29.33ft/s
Answer: 5.18 pounds
Step-by-step explanation:
Given: The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas.
Let 'p' denote the pressure exerted on the walls and 't' denotes temperature of the gas.
Then the equation is given by :-
, where c is the proportionality constant.
Also, the pressure is 6 pounds per square inch when the temperature is 440° F.

Then, the final equation to calculate pressure becomes :-

Now, the pressure exerted when the temperature of the gas is 380°F is given by :-
