The answer is obvious that is option B, however for educational purposes we will graph the different cases
using a graph tool
see the attached figure
case A-------> is a parabola is not a straight line
case B-------> is a straight line
case C-------> there are two straight line
case D-------> is a circle is not a straight line
hence
the answer is the optionB.f(x) = x + 1
If a is directly proportional to b, we have the relationship to be:

When a = 25, b = 35. Therefore, we can calculate the value of k as follows:

Therefore, the relationship is given to be:

When a = 40, we can calculate the value of b to be:

The value of b is 56.
Just imagine having 6 one blocks. Then you have 7 groups of those 6 one blocks. Then that's it!
Step-by-step explanation:
We have,
A ball is thrown into the air with an upward velocity of 36 ft/s. Its height h in feet after t seconds is given by the function :
......(1)
Part (a) :
The maximum height reached by the ball is given by :

Part (b) :
The maximum height of the ball is calculated by putting t = 1.125 in equation (1) such that :

Answer:
a = 60
Step-by-step explanation:
90 + 30 = 120
120 - 180 = 60
