Answer:

There are only 3 differences perform

Step-by-step explanation:

I. If x is negative, y is negative then the answer is possitive

eg. x is -2, y is -3

-2 × -3 = 6

II. If x is negative, y is positive then the answer is negative

eg. x is -1, y is 2

-1 × 2 = -2

III. If x is possitive, y is possitive then the answer is positive

eg. x is 2, y is 5

2 × 5 = 10

Alt. No matter how long x, y, z, a, b there always apply only 3 rules above. Multiply or Devide are the same rule.

Solve This Using The Quadratic Formula: 3x^2+9x-6=0

aivan3 [116]

<h3>Therefore either $x = \frac{-3+\sqrt{17}}{2}$ or, $x = \frac{-3-\sqrt{17}}{2}$ </h3>

Step-by-step explanation:

$3x^2 +9x -6=0$ $x = \frac{-b\pm\sqrt{b^2- 4ac} }{2a}$

$\Leftrightarrow x = \frac{-9\pm\sqrt{9^2- 4.3(-6)} }{2.3}$ here a = 3 ,b = 9 and c= -6

$\Leftrightarrow x = \frac{-9\pm\sqrt{153} }{6}$

$\Leftrightarrow x = \frac{3(-3\pm\sqrt{17}) }{6}$

$\Leftrightarrow x = \frac{-3\pm\sqrt{17}}{2}$

Therefore either $x = \frac{-3+\sqrt{17}}{2}$ or, $x = \frac{-3-\sqrt{17}}{2}$

Find the domain and range of the function

Karolina [17]

Domain- {-2, 1, 0, 1, 2}
Range- {-2, 0, 2}

My domain is right but I don’t think my range is. I did learn this 4 years ago though so

The slope of the line below is 5. which of the following is the point-slope form of the lne?

irga5000 [103]

Point-slope form of a line is

y=mx+b

where m is the slope and b is your y intercept

So, if the slope is 5, then that is your m value

y=5x+b

To find the value of b, that is just the value of where the line passes the y axis
