1.) Solve for the value of x

15/x +1 = 3/x

A) 5
B) 4
C) 1/5
D) 1/4

2.) Which of the following does not apply a Property of Proportions for x/3 = y/4

A) x/4 = y/3
B) (x + 3)/3 = (y + 4)/4
C) 3/x = 4/4
D) x/y = 3/4

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

multiply each one by 3.14

step-by-step explanation:

y=20x
