Answer:

D There is an infinite number of solutions to the system of equations

Step-by-step explanation:

When you put the first equation in standard form by dividing it by 2, you get ...

x -2y = 4

When you put the second equation in standard form by dividing it by 8, you get ...

x -2y = 4

These are the same equation, so describe the same line. There are an infinite number of (x, y) pairs that will satisfy this equation.

There is an infinite number of solutions.

ollegr [7]

Answer:

g o f = $g(f(x)) = 32x^2 + 32x + 4$

Step-by-step explanation:

Given

$f(x) = 4x +2$

$g(x) =2x^2 - 4$

Required:

Find g o f

This is calculated as:

$gof = g(f(x))$

$g(x) =2x^2 - 4$

So:

$g(f(x)) = 2(4x+2)^2 - 4$

$g(f(x)) = 2(4x+2)(4x+2) - 4$

$g(f(x)) = 2[ 16x^2 + 16x + 4)] - 4$

$g(f(x)) = 32x^2 + 32x + 8 - 4$

$g(f(x)) = 32x^2 + 32x + 4$

first you have to do the 11-9 its gonna be 2 then you have to the cubic of 2 wich is 8 and after it you have to get 8 divided by 2 youre gonna get 4

after it you have to start from the left 320/4 equal to 80 than 80by 8 equal to 640

6+b/b is an integer number. find all possible integer values of b

Andrei [34K]

Step-by-step explanation:

(6+b)/b = x (= an integer number)

6 + b = bx (= still an integer number)

6 = bx - b = b(x - 1) (= still an integer number)

b = 6/(x - 1) (= still an integer number)

now for b to be integer, (x-1) must be a factor of 6 (6 must be divisible by x-1 with 0 remainder).

and integer includes negative numbers too.

the factors of 6 are therefore

1, 2, 3, 6, -1, -2, -3, -6

so, b can be 6/±1 = ±6

b can be 6/±2 = ±3

b can be 6/±3 = ±2

b can be 6/±6 = ±1

so, all possible values for b are also the listed factors of 6 :

-6, -3, -2, -1, 1, 2, 3, 6
