x=41.25
Answer:
School X: 8 points School Y: 2.6̅ or 6 repeating.
Step-by-step explanation:
When you know that School X has <em>8 points</em>, and School Y has <em>3 times less</em>, you have to divide 8 by 3. When you do that, you get 2.6̅, or 2.6 repeating, which means that you have 2 that goes into 3 goes into 8 3 times, because 3 x 3 would be 9, which is bigger than 8. Anyway, when you divide again because you have to add a decimal point after the number to keep dividing, <em>you keep getting 6</em>. it's never going to change, because thats what 6̅ is. 6 REPEATING.
I hope this helps! ;)
<span>y = -3.5x - 3.5
y = -3.5x 3.5
I do not see a sign for the constant term (y-intercept) in the second equation.
In any case, since the equation reads y=-3.5x + (y-intercept) in both cases, the lines are parallel to each other.
If the y-intercepts are identical, then the equations are also identical, therefore there are infinitely many solutions.
If the y-intercepts are different (e.g. +3.5 and -3.5), then the two equations form distinct (i.e. not coincident) parallel lines, and therefore has solution.
So it depends on the missing sign, and you will be able to judge when the sign is given.</span>
