The function and the first value stated for x are confusing.

Doing some research, I found that the problem is to evaluate the function $f(x)=4.7^x$ for x = - 1 and x 2.

The solution is:

1) For x = - 1

$f(-1)=4. 7^{-1} =4. (1/7)=4/7$

2) For x = 2

$f(2)=4.7^2=4(49)=196$

Step-by-step explanation:

5x−4=5

1 Add 44 to both sides.

5x=5+4

2 Simplify 5+45+4 to 99.

5x=9

3 Divide both sides by 55.

x=\frac{9}{5}

Murljashka [212]

3 1/2 pound = 7/2 pounds.
We know that the dog eats 7/2 (3.5) pounds every 21 days since there are 7 days in a week and Mr.Z only buys dog food every 3 weeks.

Set up a proportion. 3.5 lb = x 
 21 days 365 days

Cross multiply and divide. 3.5 lb x 365 days = 1277.5 / 21 days = 60.83 lb

As the key suggests, the left part is the integer part of the number, while the digit on the right is the decimal part of the number.

So, for example, the first row describes the two values 97.2 and 97.8, while the second row describes the values 98.1, 98.3 (repeated twice), 98.5, 98.6 and 98.7 (repeater three times).

So, the number of values is given by the number of leaves: you simply have to count how many digits are there on the right part of the screen.

The answer is thus 24
