Part A:
1 solution. It is a linear equation => one solution.
Part B:
3(2x - 7) = 3
(divide through by 3) 2x - 7 = 1
(add 7 to both sides) 2x = 8
(divide through by 2) x = 4
we are given
To find x-intercept means we have to find zeros
and for finding zeros , we will use quadratic formula
and we have it has two x-intercepts
so, it's discriminant must be greater than 0
so, we will find discriminant
now, we can compare with
and then we can find a , b and c
now, we can find D
It has two x-intercepts
so,
now, we can solve for m

Answer:
It does not, unless or
If you remember how to raise a power to a given power you remember to multiply the exponents (or, if you don't, apply the definition of
At this point you're being asked if and the only two numbers for which this is true are 0 and 1 (side note: if the left hand side was an even function also was a possible candidate, but alas 9 is odd).
