Answer: C
Step-by-step explanation:
We can use the expanding rule to get that one if the expressions is
(9x^2 + 2x - 7)x + (9x^2 + 2x - 7)(-4)
1/2 Because 4/8 is the same as 1/2 and 3/8 is smaller
Answer: 
Step-by-step explanation:
The consecutive numbers are the numbers which come one after another .
Using Algebraic expressions
Let x be the first number , then the second number would be x+1 and the third number would be x+2.
The given statement : The sum of three consecutive integers is 765.
According to this statement , the equation will become :

Therefore, the equation that describes the statement would be :
Question 5: / Pregunta 5:
<u>b. x² + 3</u>
f(x) =

x² = y - 3
\/
x² + 3 = y
\/
x² + 3 = f(x)
Question 6: / Pregunta 6:
<u>b. Yes, but not one to one</u>
Two inputs have an output of 8 so it is not one to one, but no input has two different outputs so it is a function / Dos entradas tienen una salida de 8, por lo que no es una a una, pero ninguna entrada tiene dos salidas diferentes, por lo que es una función.
To find tax : $1,799.91 x 1.06 = $1907.9046. Because it's money, it should be rounded to $1907.90.
Of course, another way to do it is by multiplying $1,799.91 by 0.06, and adding the product that you get to 1,799.91.
Either way, you will still get $1907.9046
