1) Plug in 2 into the equation:
f(x) = 2x - 6
2) f(2) = 2(2) - 6
f(2) = 4 - 6
f(2) = -2
Feel free to ask if you need me to clarify anything! :)
Answer:
















Step-by-step explanation:
1. Three zeroes equal 1,000
2. One zero equal 10
3. One zero equal 10
4. Look at the value without the zeroes
5. Three zeroes equal 1,000
6. Look at the value without the zeroes
7. Since 890 has one zero, one more zero equal 10
8. Look at the value without the zeroes
9. Same as 8.
10. Three zeroes equal 1,000
11. Look at the value without the zeroes
12. Three zeroes equal 1,000
13. Same as 11.
14. Same as 13.
15. N/A
16. I am not sure about this one cause I don't know if there are more zeroes or not, but same as 13.
For 34, since each diameter is in scientific notation , meaning that we have one number (1-9) followed by a decimal, we simply see which has the smallest power, which is cell C.
For 35, we multiply them out to get 0.83*10^2 (we subtract exponents when dividing). Since scientific notation is one integer from 1-9 followed by a decimal, we move 0.83 one place to the right and therefore remove one power from 10^2, getting 8.3*10
Answer:
the answer is
hours
Step-by-step explanation:
so first we have to turn the fractions into mixed fractions, in order to do that we multiply the whole number by the denominator and add the numerator, our answer becomes the new numerator over the same denominator.

3 x 4 + 3
12 + 3
15

we do the same thing again.

1 x 3 + 1
3 + 1
4

then after we get our mixed fractions we subtract them from each other. Since the denominators are not the same we multiply to get the same denominators.



we subtract the numerators and keep the denominators.

then we simplify.
