Select all 4 true descriptions of the graph of y≤3x+4.

question 1 options:

a)

the y-intercept is (0, 4).

b)

the y-intercept is (0, 3).

c)

the graph is a dotted line.

d)

the graph is a solid line.

e)

the shading is above the line.

f)

the shading is below the line.

g)

the point (1, 7) is on the line.

h)

the point (1, 5) is on the line

A, D, F and G..

Step-by-step explanation:

The following are true:

A.  y -intercept: y = 3(0) + 4 = 4 so it's  (0, 4)

D. It is a solid line because the inequality sign includes 'equals'.

F. The inequality is ' lees than or equal to' so the shading is below the line.

G. y = 3x + 4 . When x = 1 y = 7 so the point (1, 7) is on the line.

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.
