Functions f (x)= 2x+3 and g (x)=6x+2 which composition produces the greatest output

Answers

Answer 1
Answer: I would start by evaluating f(g(x)) and g(f(x)) f(g(x)) = f(6x+2) = 2(6x+2) + 3 = 12x + 4 + 3 = 12x + 7 can you evaluate g(f(x)) ?

The solution to an equation is 21

Answers

an solution to an equation = 21 would be something like 2p + 7

if you wanna know how to solve this 
here is how:
Simplifying 2p + 7 = 21 Reorder the terms: 7 + 2p = 21 Solving 7 + 2p = 21 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 2p = 21 + -7 Combine like terms: 7 + -7 = 0 0 + 2p = 21 + -7 2p = 21 + -7 Combine like terms: 21 + -7 = 14 2p = 14 Divide each side by '2'. p = 7 Simplifying p = 7

5x+y=-10
7x-3y=-36

Answers

5x+y=-10\n \n 7x-3y=-36

Let's multiply the first equation by 3. (As you can see y's coefficient in the first one is 1 and in the second one is -3 , we will multiply the first equation by 3 so when we add the equations their sum will be 0)

3\cdot (5x+y)=3\cdot -10\n \n 15x+3y=-30

Now let's add this new equation and our second equation.

7x-3y=-36\n \n 15x+3y=-30\n \n (15x+3y)+(7x-3y)=(-30)+(-36)\n \n 15x+7x+3y-3y=-30-36\n \n 22x=-66\n \n x=\frac { -66 }{ 22 } \n \n x=-3

We found x=-3

Now let's plug x's value in one of the equations to find y's value.

x=-3\n \n 5x+y=-10\n \n 5\cdot -3+y=-10\n \n -15+y=-10\n \n y=-10+15\n \n y=5

So we found y=5
