The first 3 are functions as their x coordinate (number on the left side of the parentheses) is not repeated in any of the other parentheses
Answer:
y = -2/3x-9
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -2/3x+b
We have a point we can substitute into the line
-5 = -2/3(-6)+b
Subtract 4 from each side
-5-4 =4+b-4
-9 =b
y = -2/3x-9
Answer:
y= 7^-t
Step-by-step explanation:
Equation for exponential decay:
An equation represents exponential decay if a term between 0 and 1 is elevated to the independent variable.
In this question:
First option 4 is elevated, so not exponential decay.
Second option:
, thus, the second option represents exponential decay.
<span>The minute hand of a watch is 6 inches long. How far does the tip of the minute hand go in 15 minutes? How much do you move in 25 minutes?</span>
Answer:
True
Step-by-step explanation:
Take 4/11 and you get 0.363636363636, which is the same if you take 12/33. So the proportion of the two is the same.
