Answer:
1. x=18 2. x=1
Step-by-step explanation:
Its just a matter of subbing...but keep in mind, for it to be a solution, it has to satisfy all 3 inequalities
x - y > = -4
2x - y < = 5
2y + x > 1
solutions are : (-1,3) and (3,5)
Answer:
All except the second one (angle g is not similar to angle r)
Step-by-step explanation:
Just look at the order of the letters. It it's the same, its similar.
To determine the lines that are parallel, you will need to find the missing angle length in the pairs of supplementary angles (totaling 180 degree).
180 - 114 = 66 degrees
180 - 112 = 68 degrees
Using these you can see the lines that are parallel. They have matching angle measurements.
c // f
d // e
First we have to isolate the varible
-2/5x-2=18
+2 +2
-2/5x=20
then divide both sides by -2/5 to get x completely by itself
-2/5x=20
------- ---
-2/5 -2/5
x=-50
i hope i've helped!
