Find the value of x.​

Mathematics
1 answer:
tankabanditka [31]2 years ago

Answer:

13

Step-by-step explanation:

(11x - 15) + (5x - 13) = 180 (Since a straight line = 180°)

11x + 5x - 15 - 13 = 180 (Combine like terms)

16x - 28 = 180 (Simplify)

16x - 28 + 28 = 180 + 28 (Add 28 to both sides)

16x = 208 (Simplify)

16x ÷ 16 = 208 ÷ 16 (Divide both sides by 16)

x = 13 (Simplify)

Answer:

13. Answer: 0

17. Answer: 3

19. Answer: 2

Step-by-step explanation:

13. f(g(3))

First find g(3) on the right graph.

We see that at x = 3, g(x) = 4

So g(3) = 4

Next find f(g(3)). Since g(3) = 4, that means we have to find f(4) and the from the left graph we see that f(4) = 0 answer

17.f(f(5))

f(5) = 1

f(f(5)) = f(1) = 3 answer

19. g(g(2))

g(2) = 0

g(g(2)) = g(0) = 2 answer
