Answer:
f(x) = 8·1.25^x
Step-by-step explanation:
An exponential function has the form ...
... f(x) = a·b^x
Then f(0) = a. Your graph shows f(0) = 8.
The base "b" can be found from any other point on the graph. You have marked the point (1, 10), so we can find "b" from ...
... f(1) = 10 = 8·b^1 = 8b
... 10/8 = b = 1.25 . . . . . . . divide by the coeffiicient of b
Now, we know the exponential function is ...
... f(x) = 8·1.25^x
Answer:
The correct answer is f(x) = 8·1.25^x

Answer:
-3 and 4
Step-by-step explanation:
We can start naming the first number x
Hence, the second number would be 10+2x
Set up an equation.
10+2x+x=1
Combine like terms
10+3x=1
Subtract 10 from both sides
3x=-9
Divide both sides by 3.
x=-3
The first number is he first is -3.
Plug that into the expression for the second number.
10+2x
10+2(-3)
10-6
4
The two numbers are -3 and 4.

- hundredths
- seven and fourteen hundredths
- 7+.1 +.04
Step-by-step explanation:
Given:
7.14
Find:
- the whole number
- the farthest place value to the right
- the decimal in word form
- the decimal in expanded form
Solution:
a) The whole number is the integer portion, the part of the number to the left of the decimal point: 7.
__
b) The right-most place value is hundredths.
__
c) seven and fourteen hundredths
__
d) There are several versions of "expanded form." Choose the one applicable to your curriculum.
7.14 = 7 +0.1 + 0.04
7.14 = 7×1 + 1×.1 + 4×.01
7.14 = 7×10⁰ +1×10⁻¹ +4×10⁻²
