Answer:

False

Step-by-step explanation:

4x+4+5y=9xy+4

Step 1: Add -9xy to both sides.

4x+5y+4+−9xy=9xy+4+−9xy

−9xy+4x+5y+4=4

Step 2: Add -5y to both sides.

−9xy+4x+5y+4+−5y=4+−5y

−9xy+4x+4=−5y+4

Step 3: Add -4 to both sides.

−9xy+4x+4+−4=−5y+4+−4

−9xy+4x=−5y

Step 4: Factor out variable x.

x(−9y+4)=−5y

Step 5: Divide both sides by -9y+4.

x(−9y+4)

−9y+4

=

−5y

−9y+4

x=

−5y

−9y+4

Answer:

x=

−5y

−9y+4

this does not add up as in um.. i forgot the word- but yea its false

Hi there!

\large\boxed{x = \frac{\pi}{3} \text{ and } \pi}

We are given:

cos(7x)cos(4x) = -1 - sin(7x)sin(4x)

Begin by moving all terms with variables to one side:

cos(7x)cos(4x) + sin(7x)sin(4x) = -1

The corresponding trig identity is cos(A - B). Thus:

cos(7x - 4x) = cos(7x)cos(4x) + sin(7x)sin(4x) = -1

cos(3x) = -1

cos = -1 at  π, so:

3x = π

x = π/3

We can also find another solution. Let 3π = -1:

3x = 3π

x = π

Thus, solutions on [0, 2π) are π/3 and π.
