Bumek [7]3 years ago

Hi! i’m going to assume that the 2 next to the x is an exponent, so forgive me if i answer incorrectly. after plugging in x for -6 your equation should be 4(-6^2+3)-2y (the ^ indicates a exponent)

multiply the exponents and get:

4(36+3)-2y

add the parentheses:

4(39)-2y

multiply by 4:

156-2y

and divide by -2 (to isolate the y)

y=-78

this might be wrong, but i hope it helps :)

Sin C = AB / AC
We have AC. We need to calculate AB

ABC is a right triangle. Therefore, AC² = AB²+BC²
82² = AB ² + 80² => AB² = 82² - 80²
AB = 18

Sin C = 18/82 = 9/41

Good luck

3x² - 33x - 180 = 0
3(x² - 11x - 60) = 0
3(x² - 15x + 4x - 60) = 0
3(x + 4)(x - 15) = 0
3(x - 4) = 0 or x - 15 = 0
3x - 12 = 0     <u>  + 15  + 15</u>
<u>    + 12 + 12</u>           x = 15
       <u>3x</u> = <u>12</u>
        3      4
         x = 3

The answer is equal to H.15 and E. 4.
