Answer: (-4, -1)
Step-by-step explanation: Since these lines are already graphed, we are looking for their point of intersection. This point where the two lines intersect will represent the x and y that is the solution to this system of equations.
The two lines intersect in quadrant III
where x and y are both negative.
When finding the coordinates of a given point,
be very careful with your signs.
Let's just do a quick review on the coordinate system. On the x-axis, left means negative and right means positive and on the y-axis, down means negative and up means positive.
So to find the coordinates for this point, we start at the origin.
Then we move to the left 4 and down 1 so that's (-4, -1).
So the solution to this system is (-4, -1).

By using ratio, it is obtained that if there are 8 atoms of hydrogen, there are 4 atoms of oxygen.
What is ratio?
Ratio is used to find a comparision between two quantities with the same unit
The first part of the ratio is called antecedant and the second part of the ratio is called consequent.
Here,
In a molecule of water, there are 2 atoms of hydrogen and 1 atom of oxygen
Ratio of hydrogen and oxygen = 2 : 1
Number of atoms of hydrogen = 8
Let the number of hydrogen atom be 2x and number of oxygen atom be x
By the problem,
Number of oxygen atom = 4

Answer:
ok
Step-by-step explanation:
make sure to do it
320 bec 600-370= 230 then u add 90 to make 32o
