You just break it up, do 20x8 then another 20x8 then 5x8
Technically this is not necessarily true for all. A function has each input mapped to one output, therefore there can be two inputs that have the same output. However, when inverted, the input will have two outputs, which is not a function. For example with (1,3) (2,3) (3,4) (4,5) this is a function but switched (3,1) (3,2) ! Two inputs have the same output, which is not a function!
Answer:
(1,-2)

Answer: 
Step-by-step explanation:
Given
Hester get a fixed amount and an additional $15 for an extended warranty
Suppose x is the amount of fixed amount
for 15 television sale, the price is $1275
Thus, we can write
Therefore, the fixed amount of television is 
<span>w^2 + 18w + 77 = 0
breaking the middle term
</span><span>w^2 + 11w + 7w + 77 = 0
making pairs,
</span>(w^2 + 11w) + (7w<span> + 77) = 0
</span>w(w + 11) + 7(w + 11) = 0
(w+11)(w+7)=0
Hence,
the best answer is :
<span>C. (w + 7)(w + 11) </span>
