Answer:
-6
Step-by-step explanation:
we just need to do the step slope=(y2-y1)/(x2-x1)
so slope =-30-(-54)/(7-11)=24/-4=-6
1/5 (c) since it goes up only one and then over 5
Answer:
10
Step-by-step explanation:
Since m||n the sum of given angles is equal to 180 (they are supplementary)
6x + 10 + 10x + 10 = 180 add like terms
16x + 20 = 180 subtract 20 from from both sides
16x = 160 divide both sides by 16
x = 10
Answer:
Step-by-step explanation:
7x - 15 = 4x - 12
3x - 15 = -12
3x = 3
x = 1
y = 7(1) - 15
y = 7 - 15
y = -8
(1, -8)
