For this case we must find the value of the variable "x" of the following equation:

$12 = x + 3$

So, we follow the steps:

Subtracting 3 from both sides of the equation we have:

$12-3=x+3-3$

Different signs are subtracted and the sign of the major is placed:

$9 = x\\x = 9$

Thus, the value of x is 9.

Answer:

$x = 9$

Travis is deciding how to study math tonight he is choosing between studying ofG patterns P or equations E he also is deciding w

expeople1 [14]

Answer:

GT, GV, PT, PV, ET, and EV.

Step-by-step explanation:

Given that

The number of topics Travis has to chose from are 3 topics(G, P, E).

The number of ways Travis can study each topic are 2 ways(T, V).

Essentially, the number of combinations Travis is expected to be able to chose from is given as

The number of combinations = The number of topics * The number of ways

The number of combinations = 3 * 2

The number of combinations = 6

Therefore, the total possible combinations has to be

GT, GV, PT, PV, ET, and EV

Answer #6 and tell the steps of how u did it

sineoko [7]

Answer:

3131x+1

Step-by-step explanation:

Make equation simple

5x times 5x times 5x times 5x times 5x +x+1

Solve

5 times 5 times 5 times 5 times 5 = 3125

x times x times x times x times x times x = 5x

3125+5x=3130x

Now you might be thinking you cant add x but here your can because it is just broken apart

now add x+1

3131x+1

Consider the linear function f(x)=4x -5.<br> Find f(3), f(0), f(-2).

nika2105 [10]

Answer: f(3)= 7, f(0)= -5, f(-2)= -13

Step-by-step explanation:

Substitute and plug in.

For f(3), we plug in 3 for x in the equation.

So, 4(3)-5, which is just 12-5, which is 7

We do the same for f(0),

4(0)-5, which is 0-5, which is -5

Once again for f(-2),

4(-2)-5, which is -8-5, which is -13

Hope this helps!
