The answer is D The value of X can be any real number greater than or equal to 0 but the value of Y must be an interger greater than or equal to 0.
Answer:
Step-by-step explanation:
hello :
f(x)=4^x so : f(-2)=4^(-2) = 1/4^2 = 1/16
X = 40, Y = 15
40(2) + 15(2) = 80 + 30 = 110 :)
Answer:
m [slope] = 0
Step-by-step explanation:
When the slope is 0, x cancels out so the y value will remain the same.
There are several methods to finding slope but the easiest way to do this is by dividing the second y value - first y value by the second x value - first x value.
m = ∆y/∆x = y2-y1/x2-x1
You y2 and x2 are interchangable with y and x, because y1, and x1 are part of the starting coordinate,.
The reason you subtract the second
value from the first is because in a directly proportional relationship, y increases as x increases so the next x values will have a greater y value, this is a measure of steepness.
So the slope is:
-1 - -1 / 3 - -2 = -1 + 1 / 3 + 2 = 0 / 5 = 0.
