(1,-3)
(5,-27)
Step-by-step explanation:
Plug x values into the equation.
Answer:
Cost of One Journal = $3.99
Cost of One pen = $0.59
Step-by-step explanation:
Let
Cost of One Journal = x
Cost of One pen = y
We can make equation from given statements.
Mr. Bowden purchases 18 journals and 40 pencils for $95.42.

Ms. Jacinto purchases 11 journals and 16 pencils for $53.33.

Now solving these equations to find the value of x

Multiply eq(1) with 2 and eq(2) with 5

We get the value of x is: x=3.99
Now, putting value of x in equation 1 to find value of y.

So, we get the value of y: y = 0.59
Now, finding the costs:
Cost of One Journal = x = $3.99
Cost of One pen = y = $0.59
They would be alternate exterior so they would have to to be equal

Answer:
When the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas. We observe this gas as water vapor or steam.
