Answer:
Step-by-step explanation:
A function has a root only if cuts the x axis .
If it cuts once it means it has one real root, if twice then two roots and so on .
Here in the graph of G(x) shown ,it never crosses the x axis so we can say that there is no real root of the given function G(x).
It means the option A which states G(x) has zero roots is correct.
Answer:
B. divide both sides of the bottom equation by 2
Step-by-step explanation
If opposite means additive inverse, then none of the answers is correct
The given system of equations is
4x+2y=4
12x+y=22
The coefficient of y in the top equation is 2 and the coefficient of y in the bottom equation is 1.
One way to make the coefficient of y have opposite sign is to multiply the bottom equation by -2 to get:
4x+2y=4
-24x-2y=-44
Or we divide the top equation by -2
-2x-y=-2
12x+y=22
If opposite means, multiplicative inverse, then dividing through both sides of the bottom equation by 2 gives:
4x +2y=4
6x + ½y=11
Hence the second choice is correct.

Answer:
StartFraction 24 Over 65 EndFraction
Step-by-step explanation:
Total number of students = 26
Number of boys = 10
Number of girls = 26-10
=16
Eduardo has to pull two names out of the hat without replacing them.
First name
Probability= Favourable outcome/Total outcome
Probability of girls=16
Total probability=26
Eduardo has to pull two names out of the hat without replacing them.
Probability= Favourable outcome/Total outcome
=16/26
=8/13
For the second name:
Without replacement of the first hat
Probability of girls=16-1=15
Total probability=26-1=25
Probability= Favourable outcome/Total outcome
=15/25
=3/5
Probability of both of Eduardo's partner for the group project will be girls=8/13*3/5
=24/65
