Answer:
x = -8
Step-by-step explanation:
(-8, 7) and (-8, -2)
m=(y2-y1)/(x2-x1)
m=(-2-7)/(-8+8)
m=(-9)/0
m = undefined slope or no slope
x = -8
Answer:
1. (-125 a - 5.75) x + b c (605 x - 550 x^2) + 10.75
2. -125 a x + x (-550 b c x + 605 b c - 5.75) + 10.75
3. 0.25 (-500 a x - 220 b c (10 x - 11) x - 23 x + 43)
Step-by-step explanation:
Answer:
Black dogs
Step-by-step explanation:
The ratio of brown dogs to black dogs is 5:10, which simplifies to 1:2.
90 degrees, a right triangle has 1 right angle which is 90 degrees
Answer:
m < 49/12
Step-by-step explanation:
The portion of the quadratic formula under the square root sign is the discriminant.
If the discriminant is > 0 then there are two real roots.
b² -4ac > 0
-----------------------------
7² - 4(3)m > 0
49 - 12m > 0
Subtract 49 from both sides
-12m > -49
Divide both sides by -12
(when multiplying or dividing by a negative the inequality must be reversed)
m < 49/12
