Ira Lisetskai [31]3 years ago
3 0

Answer:

  • - 5 ± 11

Step-by-step explanation:

2x² + 5x - 12 = 0

  • a = 2,  b = 5, c = -12
  • x = (-b ± D)/2a
  • D = √b² - 4ac = √5² -4*2*(-12) = √25+96 = √121 = 11
  • x = (-5 ± 11)/4

Correct choice is the second one or B

2x-3y=9<br> Find slope-<br> x-intercept-<br> y-intercept-
Readme [11.4K]

get the equation in slope intercept form

2x-3y=9

subtract 2x from each side

-3y = -2x +9

divide by -3

y = 2/3 x -3

slope = 2/3

y intercept = -3

x intercept set y=0 and solve

0 = 2/3 x -3

add 3 to each side

3 = 2/3 x

multiply each side by 3/2

9/2 = x

the x intercept is 9/2 or  4 1/2
