Answer: r = 11
Step-by-step explanation:
We know that the point (-2, r) lies on the graph of:
2*x + y = 7.
Then, if we that point is on the graph of the equation, we can replace the values and we will have:
2*(-2) + r = 7
and now we solve this for r-
-4 + r = 7
r = 7 + 4 = 11
r = 11
It’s
X=58, Y=32
Z=32
Because a triangle adds up to 180 deg.
Answer: 6
8 + 8 = 16
16 - 10 = 6
Answer:
-5 If it is one of your answers it will be -5
