N = x-7
2x = 5n-7
2x = 5(x-7)-7
2x=5x-35-7
-3x=-42
x=14
n=7
7 is the answer
Answer:
C is variable. -10 times c is equal to -0.1
Step-by-step explanation:
Neither of the given graphs is the answer for your question... Since 2^y=3, y=log_2(3), by definition of log. You can see that y is a fixed value, so the graph must be a horizontal line. The value of y doesn't change as x change, since x doesn't even appear in the equation.
V=2πrh
28.27=(2)(3.14)(1.5)h
h=28.27/(2)(3.14)(1.5)
h≈3
answer c. 3.0
