Answer:
I believe the answer is m=30
Step-by-step explanation:
How I got this answer:
first cross multiply
9(m+3) = 11(m-3)
9 m - 11 m = -33 -27
-2m = -60
m= 30 - (Check if the solution is in the defined range).

Answer:
C
Step-by-step explanation:
a function is defined by each x value having only one y value
In option c, a x value of 2 could have a y value of either 1 or 7
Answer:
t = - 3, t = - 1
Step-by-step explanation:
Given
h(t) = t² + 4t + 3
To find the zeros equate h(t) to zero, that is
t² + 4t + 3 = 0
Consider the factors of the constant term (+ 3) which sum to give the coefficient of the t- term
The factors are + 3 and + 1, since
3 × 1 = 3 and 3 + 1 = 4, thus
t² + 4t + 3 = (t + 3)(t + 1) = 0
Equate each factor to 0 and solve for t
t + 3 = 0 ⇒ t = - 3
t + 1 = 0 ⇒ t = - 1
smaller zero is t = - 3
larger zero is t = - 1
