10x-2y=10 We need to solve this equation for "y" to put it into slope intercept form:
10x-2y=10
-2y = -10x +10 Subtracted 10x from both sides
y = 5x - 5 Divided both sides by -2
y = 5x - 5 Is slope intercept form
Yes, no two ordered pairs in this list has the same first element
Remember the x-value is the important one, if there are repeated x-values then it is not a function but rather a relation...
Hope this helps :)
<span>Simplifying
5x2 + -35 = 0
Reorder the terms:
-35 + 5x2 = 0
Solving
-35 + 5x2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '35' to each side of the equation.
-35 + 35 + 5x2 = 0 + 35
Combine like terms: -35 + 35 = 0
0 + 5x2 = 0 + 35
5x2 = 0 + 35
Combine like terms: 0 + 35 = 35
5x2 = 35
Divide each side by '5'.
x2 = 7
Simplifying
x2 = 7
Take the square root of each side:
x = {-2.645751311, 2.645751311}</span>
24 just finished and you gotta solve it yourself to make sure it’s right
