Answer:
31/5
Step-by-step explanation:
[f(4) - f(-1)] / 4-(-1)
Answer:
No, because as the x-values are increasing by a constant amount, the y-values are not being multiplied by a constant amount.
Step-by-step explanation:
We have a set of ordered pairs of the form (x, y)
If a function is exponential then the ratio between the consecutive values of y, is always equal to a constant.
This means that:
\frac{y_2}{y_1}=\frac{y_3}{y_2}=\frac{y_4}{y_3}=by1y2=y2y3=y3y4=b
This is: y_2=by_1y2=by1
Now we have this set of points {(-1, -5), (0, -3), (1, -1), (2, 1)}
Observe that:
\begin{gathered}\frac{y_2}{y_1}=\frac{-3}{-5}=\frac{3}{5}\\\\\frac{y_3}{y_2}=\frac{-1}{-3}=\frac{1}{3}\\\\\frac{3}{5}\neq \frac{1}{3}\end{gathered}y1y2=−5−3=53y2y3=−3−1=3153=31
Then the values of y are not multiplied by a constant amount "b"

and 4/2 = 2
Answer:
180
Step-by-step explanation:
So, lets go over what we know:
5% of x = 9
Thinking of this in decimal form, this is:
0.05 * x = 9, or 0.05x = 9
To find the answer, we must multiply both sides to get 1x.
Since 0.05 is 1/20 of 1, we must multiply both sides by 20:
0.05x * 20 = 0 * 20:
1x = 180
So the answer is 180!
Hope this helps!
