Answer:
y = -2.5x + 5
Explanation:
Convert -5x - 2y = -10 into slope-intercept form: y = -2.5x + 5
You can start solving for and graphing points by putting numbers in for 'x' in the equation, and the answer you get out will be y.
Ex: -2.5(7) + 5 = -12.5
7 is the number we inserted for x, so it is the x value. -12.5 is the number we got out of the equation, so it is the y value.
The points will now look like this: (x, y) but for the example they would look like (7, -12.5)
Plot the numbers, x being on the horizontal axis, y being on the vertical axis.
First find 7% of 2,500 which is 175, then you add 175 plus 2,500 and you get 2675. So, Mr. Osmund paid $2,675 for his computer! Hope that helps!
I got that x equals -3.809523 (repeating)
x⁴ + x = 0
x(x³) + x(1) = 0
x(x³ + 1) = 0
x = 0 or x³ + 1 = 0
- 1 - 1
x³ = -1
x = -1
