Answer:

- 2 - -12 = 2

3 9 3

Step-by-step explanation:

1_3/9 =

9 x 1 + 3 = 12

That is how I got -12/9

If you did not understand, the answer is 2/3 because -2 - -12 = 10

& -3 - -9 = 6

10/6 = 2/3

Given: sin(18m-12)=cos(7m+2), find the value of m.

V125BC [204]

Answer:

m = -2/7 + π/14 + (π n_1)/7 for n_1 element Z

or m = 2/3 - (π n_2)/18 for n_2 element Z

Step-by-step explanation:

Solve for m:

-cos(7 m + 2) sin(12 - 18 m) = 0

Multiply both sides by -1:

cos(7 m + 2) sin(12 - 18 m) = 0

Split into two equations:

cos(7 m + 2) = 0 or sin(12 - 18 m) = 0

Take the inverse cosine of both sides:

7 m + 2 = π n_1 + π/2 for n_1 element Z

or sin(12 - 18 m) = 0

Subtract 2 from both sides:

7 m = -2 + π/2 + π n_1 for n_1 element Z

or sin(12 - 18 m) = 0

Divide both sides by 7:

m = -2/7 + π/14 + (π n_1)/7 for n_1 element Z

or sin(12 - 18 m) = 0

Take the inverse sine of both sides:

m = -2/7 + π/14 + (π n_1)/7 for n_1 element Z

or 12 - 18 m = π n_2 for n_2 element Z

Subtract 12 from both sides:

m = -2/7 + π/14 + (π n_1)/7 for n_1 element Z

or -18 m = π n_2 - 12 for n_2 element Z

Divide both sides by -18:

Answer: m = -2/7 + π/14 + (π n_1)/7 for n_1 element Z

or m = 2/3 - (π n_2)/18 for n_2 element Z

-3/4x>12 solve for x

Ad libitum [116K]

Answer:

$\Huge\boxed{\mathsf{\rightarrow X$

Step-by-step explanation:

$\Large\boxed{\mathsf{SUBJECT: MATH}}$

Isolate x on one side of the equation.

Find the value of x.

First, multiply -1 from both sides.

(-3/4x)(-1)<12(-1)

Solve.

12(-1)=-12

3/4x<-12

Next, multiply 4 from both sides.

4*3/4x<4(-12)

Solve.

Multiply the numbers from left to right.

4(-12)=-48

3x<-48

Then, divide by 3 from both sides.

3x/3<-48/3

Solve.

Divide the numbers from left to right.

-48/3=-16

X<-16

$\Large\boxed{\Rightarrow \mathsf{X$

The correct answer is x<-16.

Answer:

Subtract by 5 on both sides.

Step-by-step explanation:

x+5 = -10. if you subtract both sides by 5, you will get x+5-5=-10-5, which can be simplified to x=-15.
