EXPLAIN WHY THE SYSTEM HAS THE ANSWER GIVEN. SOLVE EACH SYSTEM BY ELIMINATION TO PROVE YOUR ANSWER.
Aleonysh [2.5K]

Answer:

Step-by-step explanation:

The given system of equations is expressed as

3x + y = 9 - - - - - - - - - - - - - - -1

3x = 9 - y - - - - - - - - - - - - - -2

To apply the method of elimination, we would rearrange equation 2 so that it would take the form of equation 1. Therefore, we would add y to the left hand side and the right hand side of the equation, it becomes

3x + y = 9 - - - - - - - - - - - - - - - - -3

Subtracting equation 3 from equation 1, it becomes

0 = 0

The equations have infinitely many solutions because if we input any values of x and y that satisfies the first equation, those values will also satisfy the second equation.

Water freezes at 0° Celsius. The table shows five different temperatures in degrees Celsius. Indicate whether each temperature i
KATRIN_1 [288]
0.5 is above because that .5 of a change is keeping the water from freezing because it is still slightly babouche freezing point.

-13 is below because the number is a negative so is below 0 anyway and is below the freezing point.

100 is above because the number 100 is higher than 0 so it’s above freezing point.

5.5 is above because it is a larger number than the freezing point so the water would not freeze yet at this temperature.

-2.25 is below because it’s a negative number.

I think that’s what you meant not 100% sure but that’s how I would do it :)
