Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57

Emily's number was 28
Answer:
True
Step-by-step explanation:
Both functions are straight lines. This means they will continue in both directions forever. So the both have a range and domain of all real numbers. Linear functions commonly have range and domains of all real numbers.
Answer:
Step-by-step explanation:
f(x) = 250(10) + 10 = 2500 + 10 = 2510
Answer:
The correct option is B). 
Step-by-step explanation:
Given function is 
On simplifying,
=
=![[4x^{2}+16x+16]-(2x^{2} +6)](https://tex.z-dn.net/?f=%5B4x%5E%7B2%7D%2B16x%2B16%5D-%282x%5E%7B2%7D%20%2B6%29)
=
=
Thus, The correct option is B). 
-1x(6x - 8)
= -x(6x - 8)
= -x(6x) - x(-8)
= -6x^2 + 8x
