The average rate of change for this is the slope of the secant line that connects those 2 points (3, y) and (15, y). What we need for the slope formula of change in y over change in x are the y values which are unknown as of right now. We can find them though! Don't worry! The equation is y = .01(2)^x. Using that equation, let's sub in both the 3 and the 15 and find the corresponding y values. Subbing in first a 3 gives you y = .01(2)^3, and y = .08. Subbing in a 15 gives you y = .01(2)^15 and y = 327.68. Now we have the coordinates we need to find the slope of the secant line connecting those 2 points: (3, .08) and (15, 327.6). Fitting those into the slope formula gives us (327.68-.08)/(15-3). Simplifying that is 327.6/12 which divides out to 27.3
100 more than 146 is 246
add 100 to 146 and it becomes 246
-6z+ 12
= -6(z -2) (distributive property)
The final answer is -6(z -2)~
Answer:
18.05
Step-by-step explanation:
The sum of two supplementary angles is 180 degrees.
A+B=180.
80+B=180
B= 180-80
B=100
