Solve the quadratic equation by using either numeric or graphic approach x^2 + 2x - 3 = 0

fomenos

Answer:

Step-by-step explanation:

$x 1= \frac{ - b + \sqrt{ {b}^{2} - 4ac} }{2a} \\ x2 = \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a} \\ x1 = \frac{ - 2 + \sqrt{ {2}^{2} - 4\times 1 \times ( - 3)} }{2} = 1 \\ x2 = \frac{ - 2 - \sqrt{ {2}^{2} - 4 \times 1 \times ( - 3)} }{2} = - 3$

What is the slope intercept from of the equation of the line that passes through (7, -5) and (3, -9)

never [62]

Answer:

B. $y = x - 12$

Step-by-step explanation:

First, find the rate of change [slope]:

$\frac{-y_1 + y_2}{-x_1 + x_2} = m$

$\frac{5 - 9}{-7 + 3} = \frac{-4}{-4} = 1$

Then use the Slope-Intercept Formula instead of the Point-Slope Formula because you get it done faster that way. It does not matter which ordered pair you choose:

−9 = 3 + b

−12 = b

$y = x - 12$

________________________________________________________________________________________________

−5 = 7 + b

−12 = b

$y = x - 12$

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

I am joyous to assist you anytime.
