Is x = 6 a solution to the equation 5(x – 3) = x + 13?
Follow the steps to find out.
1. Rewrite the equation 5(x – 3) = x + 13 with 6 substituted for x. Write a question mark over the equal sign to show that you're testing to see if the equation is true.
Write your answer in the space below.

What is tangent function?One of the six fundamental functions in trigonometry is the tangent function. As stated, Tan A = Opposite Side/Adjacent Side is the Tangent Formula. Tangent may be modeled using sine and cosine as follows: Tan A = Sin A / Cos A.
Given:
tan(x)tan(x/2) = ?
We will use formula,
tanA×tanB = 1 - [(tanA + tanB )/tan(A+B)]
Substituting the values,
tan(x)tan(x/2) = 1 - [(tanx + tanx/2 )/tan(x+x/2)]
tan(x)tan(x/2) = 1 - [(tanx + tanx/2 )/tan(3x/2)]
Therefore, 1 - [(tanx + tanx/2 )/tan(3x/2)] is the solution.

Answer:
[tex] \sqrt{32} + 3[/tex]
[tex] - \sqrt{32} + 3[/tex]
Step-by-step explanation:
Use foil method
[tex](y - 3) {}^{2} [/tex]
[tex](y - 3)( y - 3)[/tex]
First multiply y and y
[tex]y \times y = {y}^{2} [/tex]
Next Multiply Outer term y and -3.
[tex]y \times - 3 = - 3y[/tex]
After that ), Multily inner tern -3 and y
[tex] - 3 \times y = - 3y[/tex]
Finally multiply -3 and -3 and you get 9.
Then combine all
[tex] {y}^{2} - 6y + 9 - 32 [/tex]
[tex] {y}^{2} - 6y - 23[/tex]
Now I'm going to complete the square. First get only the y value on the left side so we first set this equal to zero then move add 23 on both sides.
[tex] {y}^{2} - 6y - 23 = 0[/tex]
Add 23
[tex]y {}^{2} - 6y = 23[/tex]
Apply formula
[tex] (\frac{b}{2} ) {}^{2} [/tex]
where b is the coefficient.
plug it in
[tex]( \frac{ - 6}{2}) {}^{2} [/tex]
Which is -3 squared which equal 9.
Then add 9 on both sides
[tex] {y}^{2} - 6y + 9 = 23 + 9[/tex]
23+9=32
Now let factor the left side
the only number that adds to -6 and multiply to 9 is
-3 so we would rewrite the left side as
[tex](x - 3) {}^{2} = 32[/tex]
Now take the sqr root of 32
[tex] \sqrt{(x - 3) {}^{2} } = \sqrt{32} [/tex]
Then add 3 on both sides
[tex]x + - 3 + 3 = \sqrt{32} + 3[/tex]
A sqr root of a number can be positive or negative so
the answer is
[tex] - \sqrt{32} + 3[/tex]
[tex] \sqrt{32} + 3[/tex]
How many fewer students
Answer: 8 fewer students
Step-by-step explanation:
Drums - 32
Trombone - 16
Flute - 40
32 + 16 = 48
48 - 40 = 8
Hope it helps!
(Below is answer)
Step-by-step explanation: Since "fewer" means to subtract, we'll need to subtract 40 by 32.
1. 40 - 32 = ?
2. Zero cannot be subtracted by 2. Hence, we'll need to regroup.
Take one ten from the tens place. (Zero becomes 10)2a. 10 - 2 = 8
3. Solve again.
30 - 22 = 8Hence, our answer is 8.

How many times does X squared minus 4X -12 cross the X axis
We can solve this problem using discriminant.
x^2-4x-12's discriminant is
(-4)^2-4*-12=16+48 which is clearly larger than 0
This means that it crosses over the axes 2 times.
In case you don't know what discriminant is, its in equation ax^2+bx+c
the discriminant is b^2-4ac.
If its positive it has 2 crosses with x axis, if negative then 0 crosses, if 0 then 1 cross.
Hope this helped at least a little bit :D
