Answer:
65
Step-by-step explanation:
because this equals that and that proves it
Sum of interior angles of a triangle = 180
so
<span>third angle = 180 - 78 - 49 = 53

Answer:
dy/dx = (4 (x + y)^3 - y) / ( x - 4(x + y)^3).
Step-by-step explanation:
xy = (x + y)^4
Using implicit differentiation:
x dy/dx + y*1 = 4 (x + y)^3 * (1 + dy/dx)
x dy/dx + y = 4 (x + y)^3 + 4 dy/dx (x + y)^3
x dy/dx - 4 dy/dx (x + y)^3 = 4 (x + y)^3 - y
dy/dx( x - 4(x + y)^3) = 4 (x + y)^3 - y
dy/dx = (4 (x + y)^3 - y) / ( x - 4(x + y)^3)
Answer:
f and g have the same value at x = 3 and again at x = 7.
Step-by-step explanation:
Note that f(3) = g(3) = -9, and that
f(7) = g(7) = 2.
