Hey can anyone pls answer these math problems!!

Zepler [3.9K]

Answer:

1={5 and 3} 2={0} 3={0.209 and 4.791} 4={-3 and 4} 5={1 and 9} 6={-4.303 and -0.697}

Step-by-step explanation:

Your probably confused on what a, b, and c means.

The problems are written like this.

$ax^2+bx+c=0$

That formula finds the zeros.

For example 1:

$x^2-8x+15=0\\ax^2-bx-c\\a=1\\b=-8\\c=15$

Then use the formula

$x=\frac{-b+-\sqrt{b^2-4ac} }{2a} \\\\x=\frac{-(-8)+-\sqrt{-8^2-4(1)(15)} }{2} \\x=\frac{8+-\sqrt{64-60} }{2} \\\\x=\frac{8+-2}{2}\\$

If plus then 5, if minus then 3

CHECK:

$x^2-8x+15=0\\5^2-8(5)+15=0\\25-40+15=0\\0=0\\3^2-8(3)+15=0\\9-24+15=0\\0=0$

Hope this helps you understand how to do this by yourself. Now to do the rest ;-;

GrogVix [38]

Answer:

The answer to your question is x-axis, y-axis

Step-by-step explanation:

To answer this question just remember the equation of the slope

m = $\frac{y2 - y1}{x2 - x1}$

Then:

If the numerator is zero, the line is parallel to the x-axis and the slope will be zero.

If the denominator is zero, the line is parallel to the y-axis and the slope will be undefined.
