Answer:
False
Step-by-step explanation:
To be a function each x can only go to one y
The number 5 goes to both 2 and 1, which violates the rule
Therefore, this is a relation, not a function
Factor the equation into...
(3b+5)(3b+5)=0
Each factor 3b+5=0 so 3b=-5 so b=-5/3
Check:
9(-5/3)^2+30(-5/3)+25=
9(25/9)-50+25=
25-50+25=0
It checks,
So answer is A.-5/3
Answer:
The solution of this system is
(4). (6.0,5.4)
Step-by-step explanation:
First we have to find the equation of the line represented in the table; for that we have to find it's slope
and it's y-intercept
and then write it in the following form:

The slope
of the line we get from first two points:

thus we have

we find
by putting the point
into the function:


Thus we have

Now we have to find where this line intersects with
; to do this we just substitute
with
:



<em>We have the x-coordinate of the intersection.</em>
We find the y-coordinate by substituting
into
:


Thus the solution to the system is

which is option 4.
Step-by-step explanation:

so the complimentary solution is

solving for particular solution we get

to find the values of constants a,b we put values in main equation and

as g(x)=sin x
so above equation yields us

so writing the solution

using IC's to get the values for 

solving for upper range
