If f(x) = 3x - 1 and g(x) = x + 2, find (f + g)(x).

Alexxx [7]

Answer:

4x + 1

Step-by-step explanation:

Multiply f + g by x because f + g is in parenthesis:

f(x) + g(x)

Then implement equation #1 for f(x) into our equation:

3x - 1 + g(x)

Then implement the other equation for g(x) into our equation:

3x - 1 + x + 2

Then switch the positions of -1 and +x:

3x + x - 1 + 2

Simmplify:

4x + 1

Hey!

Let's write the problem.
$2x-4-5x=2$
Add like terms...
$-3x-4=2$
Add $4$ to both sides.
$-3x-4+4=2+4$
$-3x=6$
Divide both sides by $-3$ .
$\frac{-3x}{-3}=\frac{6}{-3}$

Our final answer would be,
$x=-2$

Thanks!

Please help, I'm really confused with these two questions ):

erik [133]

Step-by-step explanation:

The die is rigged, so "not 3" is not a possibility. Ruling out those branches of the tree, there are 4 possible outcomes, one of which is the desired outcome. So the probability is 1/4.

A fair die has six sides that are equally likely, so the probability of rolling more than 2 is always 4/6. The outcome of the first roll does not effect the outcome of the second roll.

Need hep teaching my daughter. Janet went to Resturant and left 20% tip. If tip was $3.20 how much was meal? Solve with equation

Stels [109]

Answer:

The meal was $16.00.

Step-by-step explanation:

since the equation for finding the tip is: decimal of percent times total bill, what you want to do is isolate the bill. you do this by dividing both sides by percent and your equation is total cost = tip/percent

let's say our total equation is x.

x=3.20/0.2

x=16

Now check your work.
