Answer:
(f◦g)(2)
Step-by-step explanation:
The rule is that f(g(x))=(f◦g)(x)
The reflection of point S across the y-axis is point V. The reflection of point Q across the x-axis and the y-axis is point V, whose coordinates are (-5,-5.5).
Answer:
80
Step-by-step explanation:
180=(50+50)+x
180 = 100+x
x=80
The perimeter of any shape is the distance all the way around it.
For a triangle, it's the sum of the three side lengths.
I would normally copy them into my answer and then add them up.
But you've set them up in such a beautiful table in the question,
you can just look at that list and add them up.
Add up all the x's : x + x + x = 3x
Add up all the plain numbers: -3 + 2 + 4 = 3
There's your perimeter . . . . . 3x + 3 .
Subtract the one value from 180 and then divide that number by 2 to get the 2 values. So if one side is 90, they other sides would be 45 each
