The first option,
both have to be negative, because they were originally both part of the one fraction, which was all negative.
Answer:
Step-by-step explanation:
Use the slope formula:
where m = slope
(-5, 0) -> means x1 = -5. y1 = 0
(7, 8) -> means x2 = 7 , y2 = 8
Substitute these values into the slope formula above and you get:
Answer:82
Step-by-step explanation:
Answer:
A triangle equals to 180. Given that it is a right triangle, one angle should be 90.
So, 90+20 = 110
180-110= 70
Therefore, the other two angles are 90 and 70.
Answer:
-2a + 20b - 2c
Step-by-step explanation:
(6a + 5b + 4c) + (–6c + 15b) + (–8a) = 6a + 5b + 4c - 6c + 15b - 8a
= 6a - 8a + 5b + 15b + 4c - 6c
= -2a + 20b - 2c
