Hey there!
The answer is C
If you plug them all in for "y", that is the only one that works.
(There is a way to solve it, though, but it's timed so I figured I wouldn't take hours to explain, comment if you want me to explain it to you, though)
Have a good day :)
Answer:
Step-by-step explanation:
On a certain hot summer's day, 691 people used the public swimming pool. The daily prices are $1.50 for children and $2.25 for adults. The receipts for admission totaled $1260.75. How many children and how many adults swam at the public pool that day?
Yes, the equation “N2 + 3H2 = 2NH3” is balanced.
Answer:
B) (3, –2)
Explanation:
The inequality is y ≤ –x + 1
There are two ways to do this. You can try the four options by seeing where they lie on the graph, or by inputting them into the inequality and seeing if they check out. I am going to do a bit of both.
I know that the solution cannot have two positive coordinates because the first quadrant is not part of the solution, so I won't guess A or C.
I'll try (3, –2) (which is option B).
On the graph, (3, –2) is on the line, which means it is part of the solution because the line is solid and the inequality is a greater than or equal to sign.
Try it in the inequality:
y ≤ –x + 1
–2 ≤ –3 + 1
–2 ≤ –2 yes this checks out.
Answer: 
Step-by-step explanation:
Let's re-write 3 as a fraction: 
Now all we have to do is multiply the numerator by the reciprocal of the denominator.
