Answer:
445
Step-by-step explanation:
Define x:
Let the sum be x
Construct the equation:
<span>The sum of 3 times a number and 5 is 2 times the number plus 15.
</span>→ 3x + 5 = 2x + 15
Solve x:
3x + 5 = 2x + 15 | Equation
x + 5 = 15 | Take away 2x from both sides
x = 10 | Take away 5 from both sides
Answer: The number is 10.
Let
x = first odd integer
x + 2 = second odd integer
x + 4 = third odd integer
x + 6 = fourth odd integer
x + (x + 2) + (x + 4) + (x + 6) = -200
4x = -200 - 2 - 4 - 6
4x = -212
x = -53
Therefore, the four consecutive integers are -53, -51, -49, -47.
Limit definition of the Derivative of a function:
At x = a:
If: h = x -π/4, we will have:
When we compare it with a limit definition:
f( x )= tan xf( a ) = 1
tan ( a ) = 1,
a = π/4
Answer:
The answer is C) {(3,2),(4,3),(5,2),(2,6)}
