Answer:
The answer is 21/35 or 3/5
Step-by-step explanation:
35-14=21
Answer:
B
Step-by-step explanation:
The exponential function has the form where a is the starting value or y-intercept. B is the rate of change and x is the variable typically time. In this situation, has starting value 4, rate 3 and a -x.
Normally an exponential curve glides left to right growing steeper as it goes. But a -x flips this behavior. The curve starts very steep then gradually slows down. This means only graphs B or D are options. Since only graph B of these two has a y-intercept at 4, graph B is the solution.
X is equal to zero because the equation for slope is the change in Y/change in x.
If we plug in the known values and set the equation equal to -2, x is 0. (4-8/2-x=-2 , 4-8/2-0= -4/2 or -2).
You can ask me any questions if my explanation what confusing haha.
Answer:
#6 is 17 days
Step-by-step explanation:
This is how I answered it
1) 2750 = 550 + 125x
2) subtract 550 from each side
2750-550=2200
so the left over equation is:
2200 = 125x
3) divide each side by 125 to get x by itself
2200÷125= 17.6
4) you are left with: x = 17 days
