============================================
Work Shown:

---------------
Explanation:
The idea is to first get all the y terms to one side. I did this by subtracting 2y from both sides in the third step.
Then factor out y and divide both sides by (8x-2)
Afterward there's the optional steps of simplifying (as shown in the final two steps).
For this case we have the following exponential function:

To find the value of f (-2) what we must do is substitute the value of x = -2 in the given function.
We have then:

Then, rewriting the function we have:

Finally, simplifying we have:
Answer:
The value of f (-2) is:
option B
Answer:
She has 100 ounces.
Step-by-step explanation:
Since one bag has 8 apples, two of the bags have 8 apples and the one half bag of apples has 4 apples.
Then, since each apple weighs 5 ounces you multiply:
Equation:
= 2 1/2 × 8
= 5/2 × 8
= 40/2
= 20
20 x 5 = 100
Answer:
option-1
option-2
Step-by-step explanation:
Suppose, we have to find distance between x=a to x=b
so, we get distance
distance = b-a
or we can also write as
distance =|b-a|
or
distance =|a-b|
we are given
the distance between 1.8 and 9.4 on the number line
we can write distance as
distance =|9.4-1.8|
distance =|1.8-(9.4)|
so, option-1 and option-4......Answer
