Answer:

the x and y is 6 and -4 respectively

Step-by-step explanation:

The computation of solving the system of equations is given below:

Given that

5x - 7y = 58

And,

y = -x + 2

Put y value in the first equation

5x - 7(-x + 2) = 58

5x + 7x - 14 = 58

12x = 58 + 14

12x = 72

x = 6

So y = -6 + 2

= -4

Hence, the x and y is 6 and -4 respectively

What's equivalent to y^9 - y^3

Yuki888 [10]

Y^9-y^3 can also be written as y^9-y^3=x
so it is also equivalent to x+y^3=y^9
and x-y^9=-y^3

The recursive function LaTeX: f\left(0\right)=1,\:f\left(n\right)=f\left(n-1\right)+2nf ( 0 ) = 1 , f ( n ) = f ( n − 1 ) + 2 n

Question:

The recursive function $f(0) = 1$ , $f(n) = f(n-1) + 2n$ represents the nth term of a sequence. Determine the explicit function

Answer:

$f(n) = n^2 + n+1$

Step-by-step explanation:

Given

$f(0) = 1$

$f(n) = f(n-1) + 2n$

Required

Write an explicit formula

Let n = 1

$f(1) = f(1-1) + 2*1$

$f(1) = f(0) + 2$

$f(1) = 1 + 2 = 3$

Let n = 2

$f(2) = f(2-1) + 2*2$

$f(2) = f(1) + 4$

$f(2) = 3 + 4 = 7$

Let n =3

$f(3)=f(3-1) + 2 * 3$

$f(3)=f(2) + 6$

$f(3)=7+ 6 = 13$

Let n = 4

$f(4) = f(4 - 1) + 2 * 4$

$f(4) = f(3) + 8$

$f(4) = 13+ 8 = 21$

So, we have:

$f(1) = 3= 1 + 2 * 1=1+0*1*2*1$

$f(2) = 7= 3 + 2 * 2=1+1*2+2*2$

$f(3) = 13= 7 + 2 * 3= 1+2*3+2*3$

$f(4) = 21 = 13 + 2 * 4= 1+3*4 +2 *4$

Following the above pattern:

$f(n) = 1 + (n - 1) * n + 2 * n$

$f(n) = 1 + n(n - 1) + 2n$

Open bracket

$f(n) = 1 + n^2 - n + 2n$

$f(n) = 1 + n^2 + n$

$f(n) = n^2 + n+1$

Can someone please help

Andru [333]

A) Growth: f(x) because it is getting larger exponentially due to an integer greater than 1 being raised to an exponent.

b) Decay: g(x) because it is getting smaller exponentially due to an integer less than 1 being raised to an exponent.

c) Have the lead exponent being not equal to 1.

d) Whether or not the number being raised to the exponent is greater than or less than 1.

e) f(x) because it is an exponential growth function, which none of the others are.
