The right answer is
H=(1)/(2)r+3b-(1)/(4)=
r=2H-6b+(1)/(2)
F(5) would be 16. because f(1) is only 3.2 so if you multiply 3.2 x 5 you will get 16
assuming the scale is by 1,
a) the slope is rise/run so it rises 3 units and moves 4 units right therefore the slope is 3/4
b) the y intercept is where the line crosses the y axis so by looking at the graph you can tell that the y int is 1
c) and the equation is made up of the slope and the y intercept: y= 3/4x + 1
Factorize the quadratic trinomial
by the rule:

1. Find the roots:

2. Factorize the polynomial:

3. Only factor x-2 is given in options, then the correct choice is B.
