4(x² - 2) = 28

1. Distribute the 4
4x² - 8 = -28

2. Plug in 3 and -3
4(3)² - 8 = 28
4(-3)² - 8 = 28

3. Square 3 and -3
4(9) - 8 = 28
4(9) - 8 = 28

28 = 28

The reason both answers are the same is because whenever you put a negative number to an even power, the result becomes positive because any negative multiplied by a negative number is always positive.
28 = 28

bogdanovich [222]

Answer:

$\displaystyle y = - \frac{1}{2} x - 3$

Step-by-step explanation:

we are given a line

we want to figure out the equation of theline remember the slope-intercept form of linear equation:

$\displaystyle y = mx + b$

where:

m is the slope of the equation
b is y-intercept

from the graph we can clearly see that the line passes y-intercept at <u>(</u><u>0</u><u>,</u><u>-</u><u>3</u><u>)</u> point therefore b is <em>-</em><em>3</em>

to figure out m we can consider the following formula:

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

from the graph we obtain:(0,-3),(2,-4)

$\displaystyle m = \frac{ - 4 - ( - 3)}{ 2 - 0}$

simplify substraction:

$\displaystyle m = - \frac{ 1}{ 2 }$

now altogether substitute:

$\displaystyle y = - \frac{1}{2} x - 3$

and we are done!
