2x - 5y = 11. (4, a). x = 4, y = a
Substituting into 2x - 5y = 11
2(4) - 5(a) = 11
8 - 5a = 11
-5a = 11 - 8
-5a = 3
a = 3/-5 = -3/5 =- 0.6
Other coordinate = -3/5 = -0.6
Answer: D) 18
Step-by-step explanation:
6 - x = -12
Subtract 6 from both sides.
-x = -18
Divide by -1 on both sides so as to isolate x.
x = 18
One dice has 6 sides and two dice will give us 12 sides with 36 possibilities
it will be 9/36=.25
so it will have 25% chance of the two dice to have a sum of 9
Answer:
perpendicular
Step-by-step explanation:
if you find the slope of the points, they are completely opposite 4/3 and -3/4
y - 4 = -2 ( x - ( -11)) which would simplify to y - 4 = -2 ( x + 11) !!
