Answer:
x = 15
Step-by-step explanation:
Since it a right triangle we can use the Pythagorean theorem
c² = a² + b²
c = hypotenuse
a, b = legs
plug in the values
x² = 9² + 12²
solve
x² = 81 + 144
x² = 225
x = 15
Answer:
Step-by-step explanation:
for table the equation is
A) y = 2x + 5
for graph equation is
y = 1/2x -1
Your sequence appears to be geometric with a common ratio of 2. It can be described by
a(n) = (-2 2/3)·2^(n-1)
_____
This can be written in a number of other forms, including
a(n) = (-8/3)·2^(n-1)
a(n) = (-1/3)·2^(n+2)
a(n) = (-4/3)·2^n
Answer:
8
Step-by-step explanation:
18+8=26
26 / 3 = 8
