Answer:

Step-by-step explanation:

3/7x+5=8

Subtract 5 from each side of the equation.

3/7x=3

Divide each side by 3/7

X=3/ (3/7)

To divide by a fraction, we Can flip the fraction, (7/3) and multiply.

X= 3(7/3)

X=21/3

X=7

Identify the independent and dependent variables. Write a function in function notation. Then use the function to solve the prob
bekas [8.4K]

Answer:

He is being paid $180 on Monday.

Step-by-step explanation:

Since it asks for function notation, I'll relate the variables accordingly. So, x, the independent variable, is the one that is being adjusted. That would be the amount of miles that he is assigned so x = miles assigned. Next, the dependent variable, f(x), is the amount of cash he is paid, so f(x) = total amount paid.

Here is the function that can be used to represent the situation:

f(x) = 3.50x + 75

Now, plug in 30 to find out how much he earns after completing a 30 mile route:

f(30) = 3.50(30) + 75

f(30) = 105 + 75

f(30) = 180

Also, the $75 is a fixed amount. No variable association.

What is 2 to the power of -2? My teacher said it does not equal -4… does it equal positive 4??
mihalych1998 [28]

Answer:

1/4

Step-by-step explanation:

2 to the power of -2 would be 1/4.

This is because 2 to the power of -1 would be 1/2. And the power of 2 would square the 2 as the denominator making it 1/4.

The reason -1 makes the 2 turn into a fraction is that to the power of 2 means 2x2, to the power of one means 2, The power of zero would therefore divide by 2 so 2/2 = 1 and so 2 to the power of -1 would be 1/2.
