If you would like to simplify the expression (x - 8y) - (2x - 4y), you can do this using the following steps:
(x - 8y) - (2x - 4y) = x - 8y - 2x + 4y = -x - 4y
ax + by = -x - 4y
a = -1
b = -4
The value of b would be -4.
If you would like to simplify the expression (4x - 6) - (3x + 6), you can do this using the following steps:
(4x - 6) - (3x + 6) = 4x - 6 - 3x - 6 = x - 12
The correct result would be x - 12.
Step-by-step explanation:
- 5x²-45=0
- 5x²=45
- x²=9
- x=√9
- x=3
hope it helps.
Answer:
mmm, well, not much we can do per se, you'd need to use a calculator.
I'd like to point out you'd need a calculator that has regression features, namely something like a TI83 or TI83+ or higher.
That said, you can find online calculators with "quadratic regression" features, which is what this, all you do is enter the value pairs in it, to get the equation.
