since it states that they hired 2 buses
and the equation is coming up with the total number of students ,
the letter b is for the number of students that rode each bus
Answer:
x = 4
Step-by-step explanation:
Simplify then isolate x
4 (-x + 1 ) = -2 (x + 2) Distribute across brackets
-4x + 4 = -2x - 4 Add 2x to both sides
-2x + 4 = -4 Subtract 4 from both sides
-2x = -8 Divide both sides by -2
x = 4
Answer:
Step-by-step explanation:
Any side to side movement of a function will be reflected inside a set of parenthesis with the x. For example, if the function was a parabola, the parent graph could be, very simply,

Side to side movement would make the equation look like this:

where h is the x coordinate of the vertex.
Up or down movment would make the equation look like this:
for movement upwards, or
for movement downwards. The k represents the y coordiante of the vertex in this parabola.
Because our function has NO numbers inside the parenthesis with the f(x), but it has a -1 after, we are moving the parent graph of this function, whatever it is, down one from its starting position.
The answer is 400 not 435 only the 4 is 400
