Let the equation of a line be described by Equation A:

umka2103 [35]

10y - 5x = 40 Add 5x to both sides
10y = 5x + 40 Divide both sides by 10
y = $\frac{1}{2}$ x + 4

The y-intercept is 4 and the slope of the line is $\frac{1}{2}$ .

You can find these by comparing your equation to the equation y = mx + b, where m is the slope of the line and b is the y-intercept.

Find the sum and product of the roots. 2x^2 + 6x - 8 = 0

netineya [11]

Suppose you can factorize:

$ax^2+bx+c=a(x-r_1)(x-r_2)$

Then by expanding the right side, you have

$ax^2+bx+c=a(x^2-(r_1+r_2)x+r_1r_2)=ax^2-a(r_1+r_2)x+ar_1r_2$

which means in this case, you have to have

$\begin{cases}6=-2(r_1+r_2)\\-8=2r_1r_2\end{cases}\implies\begin{cases}r_1+r_2=-3\\r_1r_2=-4\end{cases}$

How do you write 720,080 in expanded form with exponents

liraira [26]

The expanded form for that problem would be (7x10^5) + (2 × 10^4) + (8x10^1)
when i put ^then a number i mean to that power like 2 to the 4th power i would write 2^4
