Answer:

f(2) = - 5

Step-by-step explanation:

Using the recursive rule and f(1) = - 3 , then

f(2) = 2f(1) + 1 = 2 × - 3 + 1 = - 6 + 1 = - 5

Whats wrong in this equation ?

Inga [223]

The second step is wrong. What should've been done is to find greatest common factor (gcf) of 1/6 and -2. This is because you cannont add together a number with a variable to a number without a variable. So get the variable by itself by subtracting 1/6 from both sides.

1/5x + 1/6 = -2
___— 1/6_— 1/6
____________

Turn -2 into a fraction and find the gcf of -2 and 6:

1/5x + 1/6 = -2
___— 1/6_— 1/6
____________

1/5x = -2/1 — 1/6 ——> 1/5x = -12/6 — 1/6
1/5x = -13/6

Then divide each side by 1/5 to get the variable by itself; remeber: when dividing a fraction by a fraction, you multiply by the reciprocal.

5/1 • 1/5x = -13/6 • 5/1
x = 65/6

Then, simplify

65/6} 10.83 or 10 83/100

Compute the permutation.

Anon25 [30]

So you have 8 digits (number available) to form 3 digit numbers (number selected).

Using the formula $^{a} P_{c}$ where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.

The number of three digit numbers that can be formed = $^{8} P_{3}$
= 336

 O R

By using the formula $Permutation = \frac{a ! }{( a - c) !}$ where a is the number of available digits and c is the number of digits to be selected.

⇒ $Permutation = \frac{8 ! }{( 8 - 3) !}$

⇒ $Permutation = \frac{40, 320 }{120}$

⇒ Permutation = 336

Answer:

785

Step-by-step explanation:

Plug Each of the Numbers given in for their associated variable

(25-10)^2 + 10(56)

(15)^2 + 560

225 + 560

so 785
