If y = 10, 4*10 is 40. 40/5 is 8.

your question: 

Help and explain please!

Help and explain please! 2x+3y=12

Help and explain please! 2x+3y=12Solve for y.

answer: 

2x + 3y = 12

so basically we want to get y by its self.

first were going to get y on the left side and everything else on the right. in order to do that we have to subtract 2x from the left and do the same on the other side.

2x + 3y=12

-2x. -2x

3y = 12 -2x

then we divide everything by 3 on the other side to get y by its self.

3y = 12-2x

--- ----. ----

3. 3. 3

y= 4 -2/3x

should be your answer.

Hope this helps, have a great day!

The answer is 66.54 because you do 3.14 times 11 which equals 34.54 and then add 32 which comes out to 66.54

Find the values for which the statement is true and mark them on the number line: |x|=x

gogolik [260]

Answer:

The function f(x) = IxI works as follows:

if x ≤ 0, then IxI = -x

if x ≥ 0, then IxI = x

notice that if x = 0, then I0I = 0 = -0

Now, we want that:

IxI = x

Then we have that x must be greater or equal than zero:

x ≥ 0.

To represent it in the number line, you should use a black dot in the zero an shade all the right region:

__-2__-1__0__1__2__3__4__5__6__....

5 - 3tan3x = 0 trên -π< x < π.

serious [3.7K]

Answer:

x = 0.343

Step-by-step explanation:

We want to solve:

5 - 3tan(3x) = 0

such that:

-π< x < π

where π = 3.14

then:

-3.14 < x < 3.14

Let's solve the equation:

5 - 3tan(3x) = 0

-3tan(3x) = -5

tan(3x) = -5/-3 = 5/3

Now we can use the inverse tan function, Atan(x).

Remember that:

Atan( tan(x) ) = tan( Atan(x)) = x

Then if we apply that function to both sides, we get:

Atan( tan(3x)) = Atan(5/3)

3x = Atan(5/3)

x = Atan(5/3)/3 = 0.343
