This is an example of independent events. Rolling a pair of number cubes has nothing to do with and will not affect the outcome of you flipping a coin.
A) Independent
-10 + (-7) and -10 - 7
-10 + 7 and -10 - (-7)
-1 / -1/4 and 1(4)
-1(4) and 1 / -1/4
Answer:
Step-by-step explanation:
In general, a solution of a system in two variables is an ordered pair that makes BOTH equations true. In other words, it is where the two graphs intersect, what they have in common. So if an ordered pair is a solution to one equation, but not the other, then it is NOT a solution to the system.
Answer:
y = -2x - 3
Step-by-step explanation:
The altitude will be a line perpendicular the the opposite side DE.
The slope of DE = (3 - -1) / (3 - -5)
= 4/8 = 1/2
So the slope of the altitude = -1 / 1/2 = -2
Thus the equation of the altitude through F (1, -5) can be found using the point-slope form y - y1 = m(x - x1):-
y - -5 = -2(x - 1)
y + 5 = -2x + 2
y = -2x + 2 - 5
y = -2x - 3 (answer)
