Which linear inequality is represented by the graph?
y> 2x + 2
yz 1x+1
y> 2x + 1
yz 2x+2

y> 2x + 1

Step-by-step explanation:

The only graph that has a y-intercept of 1 (as shown on the graph and a slope of 2 (steeper than a slope of 1) is the third answer choice listed.

y> 2x + 1 is correct

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: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
