A hexagon has 6 sides. You can remember this because the prefix "Hexa" means "6", such as in the word "Hexarchy"- an alliance between 6 individual civilizations, such as states or countries. : )

Which values of c will cause the quadratic equation –x2 + 3x + c = 0 to have no real number solutions? Check all that apply.

rodikova [14]

Answer:

-5

negative nine-halves

Step-by-step explanation:

we know that

In the quadratic equation $ax^{2} +bx+c=0$

If $b^{2}-4ac < 0$

then

The system has no real numbers solutions

we have

$-x^{2} +3x+c=0$

$a=-1,b=3$

substitute

$3^{2}-4(-1)c < 0$

$9+4c < 0$

$c < -\frac{9}{4}$

<u><em>Verify each case</em></u>

case 1) -5

For c=-5

substitute

$-5 < -\frac{9}{4}$

$-20 < 9$ ------> is true

therefore

The value of c=-5 will cause the quadratic equation to have no real number solutions

case 2) negative nine-halves

For c=-9/2

substitute

$-9/2 < -\frac{9}{4}$

$-36 < -18$ ------> is true

therefore

The value of c=-9/2 will cause the quadratic equation to have no real number solutions

case 3) negative one-quarter

For c=-1/4

substitute

$-1/4 < -\frac{9}{4}$

$-4 < -36$ ------> is not true

therefore

The value of c=-1/4 will not cause the quadratic equation to have no real number solutions

case 4) 1

For c=1

substitute

$1 < -\frac{9}{4}$ ------> is not true

therefore

The value of c=1 will not cause the quadratic equation to have no real number solutions

case 5) 9 Over 4

For c=9/4

substitute

$9/4< -\frac{9}{4}$ ------> is not true

therefore

The value of c=9/4 will not cause the quadratic equation to have no real number solutions

What is the equation of the line, in slope-intercept form, that passes through the point (0,7) and is perpendicular to the line

Alex Ar [27]

A line perpendicular to another occurs at the negative reciprocal of the slope of the original line. Why this is, I can further explain in the comments if you're interested. What is a reciprocal though? a reciprocal, if you're unfamiliar, is just the flipped form of it.

As an example, the negative reciprocal of 1/4 is -4/1. I multiplied 1/4 by a negative, and flipped the fraction.

So, what would the negative reciprocal of 3 be? well, you can imagine 3 to be 3/1 to help. so we multiply it by a negative, which gives us -3/1, and then we flip it, giving us -1/3. This is the slope of our unknown line. Because of this, we can mark out...well all of them haha. You need to double check your question and answers provided. With the info you've given me, none of your answers are correct. Let me know what happened if you can! if not, I would question your teacher, cause they messed up somewhere haha.
