Add 72, 75, and 83, which equal 230. Then, since there are three values, you divide the total (230) by 3, which would equal 76.6 (cont), therefore meaning they can only raise their average (using the three tests, from a base grade of 0) to a 76.6 percent (or 77 if teacher rounds grade)

x < 2
Answer:
(17-3)/2=7 games
Step-by-step explanation:
So she paid $3 for shoes so we can take away $3 from $17 then we can take that answer and divide it by 2 (because it is $2 per game) and we will get our answer. The equation would be:
(17-3)/2
17-3 is in () because we have to do that first and parenthesis are the p in order of operations (pemdas). Now to solve:
parenthesis first:
(17-3)/2=
14/2=
7

Answer: Hello mate!
we have the function y = f(x) and we want to see how the next changes affect the graph of it:
a) y = 5f(x)
this is a "dilatation" in the y-axis, this means that the graph is 5 times higher than the original graph.
b) y = f(x − 4)
Now we have y = f(0) when x = 4, so here we have the whole graph translated to the right by 4 units
c) y = −2f(x)
This case is similar to the case in a, here we have dilatation of 2 units, but also the points where before the graph was positive, now is negative, and where the graph was negative, now is positive.
So we also have a reflection over the x-axis
d) y = f(3x)
Now, in the point x = 1, we have the value of y = f(3), this means that the value of y = f(1) is in between the x values of 0 and 1, then this is a contraction in the x-axis by 3 times.
e. y = 2f(x) − 5
Ok, here we have two things.
First, you can see another dilatation in the y-axis, but here we also have a subtraction of a constant, this means that the graph is dilated two times in the y-axis, and is translated by -5 units in the y-axis ( translated down by 5 units)
