Answer:
1. no solution 2. has one solution
Step-by-step explanation:
first you must find the discriminant of each quadratic also remember
if the discriminant is positive b^{2}-4ac> 0, then the quadratic equation has two solutions.
if the discriminant is equal b^{2}-4ac= 0, then the quadratic equation has one solution.
if the discriminant is negative b^{2}-4ac< 0, then the quadratic equation has no solution.
1. the discriminant is 
and when you plug in the numbers you get -55 which is less than 0
2. the discriminant is 0 so there is one solution
Answer:
Domain: (all real numbers)
Range: (all real numbers)
Step-by-step explanation:
p(x)= 1/2*x-3
the domain is the possible values for x
this will work for all values of x
Domain: (all real numbers)
the range is the possible values for the output or p(x)
we can get out any value for p(x)
Range: (all real numbers)
The denominator of the second fraction can be factored as (a-2)(2a-7), then it becomes doable. You cancel the (2a-7) factors, and are left with:
Do note that you have erased the fact that a≠0 and a≠7/2, so you should always mention that.
I think it is 415 sorry if I am wrong. =) =)
A sample. At least that's what it's referred to as in statistics
