5 0

Answer:

For -7x^2 - 6x + 9: -\frac{3+6\sqrt{2} }{7} -\frac{3-6\sqrt{2} }{7}

For 3x^2 -x + 7: \frac{x+i\sqrt{83} }{6} \frac{x-i\sqrt{83} }{6}

Step-by-step explanation:

Find the zeros using the quadratic formula. Solution attatched. I apologize for poor handwriting. Also, there should be a negative sign before the answer to the first expression in the solution.

What is an equation of the line that passes through the points (4,-2) and (8,3)?​
Maslowich

Answer:

y-4=\frac{5}{4} (x+2)

Step-by-step explanation:

First you can find the slope of the line that would pass through those two points using the formula:

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m = \frac{3-(-2)}{8-4}

m=5/4

Now you can just plug the slope and one of the points into point-slope form for an equation of the line that will pass through both points. You can choose either point here: I'll just use the first one.

So,

y-4=\frac{5}{4} (x+2)

(don't leave out the parentheses!)
