Answer:
12 miles
Step-by-step explanation:
30-6=24
24/2=12 miles
Answer:
$150
Step-by-step explanation:
Mary+4 friends=5 people
5 people x $30 each person = 150 in total
$150
<span>1 12 f(x) = g(x)
or 112*(</span>14x3 + 28x2 – 46x )= <span>2x + 7
and </span>112*(42 +56 – 46x )= <span>2x + 7
</span>112*(98 – 46x )= <span>2x + 7
</span>and 10.976- 5.152x=2x+7
and -5.152x-2x=7-10.976
we have -5.154x= -10.969
and x= 10.969/5154
Have fun
Answer:
The answer in each numeral is:
- <u>f(4) = 28</u>
- <u>f(10) = -19</u>
- <u>f(-5) = -33</u>
- <u>f(9) = -9</u>
Step-by-step explanation:
To obtain the result in each case, you must replace the variable (n) by the value that appears in the second case, I'll explain it with the first exercise:
- 1. f(n) = 5n + 8
- f(4) = ?
As you can see, in the second doesn't appear f(n), but f(4), that means you must replace the "n" in the equation by 4, if we do this, we obtain:
- 1. f(4) = 5*(4) + 8
- f(4) = 20 + 8
- <u>f(4) = 28</u>
The first answer is 28, now we'll continue with the next exercises:
- 2. f(n) = -2n + 1
- f(10) = -2*(10) + 1
- f(10) = -20 + 1
- <u>f(10) = -19</u>
- 3. f(n) = 6n - 3
- f(-5) = 6*(-5) - 3
- f(-5) = -30 - 3
- <u>f(-5) = -33</u>
- 4. f(n) = -n
- <u>f(9) = -9</u>
In this form, <u><em>you can prove the answers are: 28, -19, -33, and -9 respectively</em></u>.
I got E and F. A would be correct as is I think, B is 9^2x, C, correct as is, D, is 9 ^2x, and E and F is 9^x
