Answer:
y=-50*0.2^x
Step-by-step explanation:
the formula for an exponential function is:
y=a*b^x
what do we multiply -50 by to get -10?
-50x=-10
x=-10/-50
x=1/5
x=2/10
x=0.2
This initial value here is -50, it is the first in the table
y=-50*0.2^x
Answer:
157 inches squared
Step-by-step explanation:
Divide the figure into smaller figures (see image for one way):
Then, find the area of each figure. In my example:
= (4x5)+(5x12)+(11x7)
= 20+60+77
= 80+77
= 157 inches squared
Answer:
y=2x+1
Step-by-step explanation:
To find the answer, first graph the equation and find coordinates for atleast 2 points. We can find (0,7) and (1,9). Next we add 3 to the x coordinate of each point. We get (3,7) and (4,9). We know the slope which is 2. So our equation becomes y=2x+b. Next we substitube a coordinate pair, with y and x in the equation. We get 7=2*3+b. Solve and we get 1=b.
Therefore,
y=2x+1.
I hope this helps.
