<span>2k² = 9 + 3k
⇒ </span><span>2k² - 9 - 3k
= 0
⇒ 2k² - 3k -9 = 0
b² - 4ac = 3² - 4*2*(-9) = 81>0
It has 2 real roots.

Answer:
(0,5)
Step-by-step explanation:
Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=1/2x + 6 is 1/2. The slope perpendicular to it is -2.
Using m=-2, substitute it and (4,-3) into the point slope form and simplify to find the y-intercept.
The equation is now in slope intercept form y=mx+b and b is the y-intercept. The y-intercept of y=-2x+5 is (0,5).
A = 1944 m²

Answer:
$329.44
Step-by-step explanation:
$50-25= 25
25.00-2.45=22.55
299.89+22.55=322.44
322.44+7.00= 329.44
I didnt see april 15 if its supposed to be added i there just add 299.89 to the total.
what is the product of -15*(-1/2)
-15 * (-1/2)
-15 * -0.5 =
7.5
