Answer:
x=6, x=-5
Step-by-step explanation:
Factoring this quadratic gets you (x-6)(x+5)=0, for this to be possible, either x-6 or x+5 has to be zero, so therefor x is 6, or x is -5
Answer: The graph is attached.
Step-by-step explanation:
The region is limited by two lines:
and 
You can write the first inequlity
in the following form:

This region are all the values for which the y-axis is less than the line f(x)=x+6 (all the values under the line).
The other inequality x ≤ 4 are all the values for which the x-axis is less than the line x=4 (all the values to the left of the line).
Observe the graphs attached.
40 is 41.6666666667% of 96
Multiply 4x12x2x36
I think
(7.5-3.5)/(4.5-2.5)= 4/2= 2
y - 7.5 = 2(x - 4.5): the answer
To complete: y - 7.5 = 2x - 9
y = 2x - 1.5
