Step-by-step explanation:
You know that 500=100%, so we can set up the following
15%(500/100%) = 75
so the discount 75 dollars
Answer:
-1/2
Step-by-step explanation:
cos(x+pi) = -cos(x), so the answer is -1/2.
Answer:
D
Step-by-step explanation:
The fruit punch has 2.4 gallons but x %
Apple juice has 5.6 gallons but 100 % or 1
The total mixture would then have 8 gallons and 82 %.
2.4+5.6=8
8×0.82 = 6.56
Then you would do 2.4x + 5.6(1) = 6.56
2.4x + 5.6 = 6.56
2.4x = 0.96
0.96/2.4 = 0.4 = 40%
Therefore, Brand A has 40% fruit juice

Step-by-step explanation:</h3>
Functions are a set of points that show how dependent variables change through independent variables.
Defining a Function
In functions, each x-value is assigned to exactly one y-value. This means that x-values do not repeat. So, if there is one x-value more than once in a set, then it cannot be a function.
For example, set B has the x-value 3 and 4 repeated twice. Thus, it does not represent a function.
Graph of a Function
Functions can also be defined through a graph. Just like with coordinate points, x-values do not repeat on the graph. You can use the vertical line test to see if a graph is a function. If you can draw a vertical line at every point on a graph without it ever intersecting with the graph more than once, then it is a function.
