Answer: The exponential function would be
Step-by-step explanation:
Since we have given that
We have points (0,15) and (2,24)
First we take when x= 0, y = 15.
So, our equation becomes,
and we take when x = 2 and y = 240
So, the exponential function would be
Answer:
x = 4
Step-by-step explanation:
1.3x - 10 = 0.8x - 8
Add 10 to both sides.
1.3x = 0.8x + 2
Subtract 0.8x from both sides.
0.5x = 2
Divide by 0.5.
x = 4.
Proof:
1.3x - 10 = 0.8x - 8
1.3(4) - 10 = 0.8(4) - 8
5.2 - 10 = 3.2 - 8
-4.8 = -4.8
