Can somebody solve using elimination method algebra2

Answers

Answer 1

Answer: For the first one, you just add them and you obtain an equation in y. Solve for y, then substitute y for the solution in either of the equations, then solve for x.
In the second one, multiply the first by -2, then do the addition and something similar to the first one.

Let z =8(cos (pi/3) + i sin (pi/3)) and w= 3(cos(pi/6) +isin (pi/6)

Which statement describes the geometric construction of the product zw on the complex plane?

Answers

No statements are given...

At the very least, we can compute the product zw by multiplying the moduli and adding the arguments. That is, if

z = 8 (cos(π/3) + i sin(π/3))

w = 3 (cos(π/6) + i sin(π/6))

then their product is

zw = 8•3 (cos(π/3 + π/6) + i sin(π/3 + π/6))

zw = 24 (cos(π/2) + i sin(π/2))

zw = 24i

The product of complex numbers z and w results in a point that is situated along the positive y-axis in the complex plane, being 24 units away from the origin.

In complex numbers, the geometric meaning of a product of two numbers, here zw, corresponds to the multiplication of the moduli and the addition of the arguments of the two numbers.

Here, z = 8(cos (pi/3) + i sin (pi/3)) and w = 3(cos(pi/6) + i sin (pi/6)), so the modulus of zw is 3*8 = 24.

The argument is the sum of the arguments (pi/3 + pi/6) which is pi/2. Hence, the product can be rewritten as zw = 24(cos(pi/2) + i sin(pi/2)). This geometric construction will situate the point along the positive y-axis in the complex plane, with a distance of 24 units from the origin.

Solve for y. 7y-4y=6 Simpify your answer as mucls as possible.

Answers

Answer: y = 2

Step-by-step explanation:

First, we combine like terms.

7y-4y = 6

Since the terms are already combined, we can solve this equation.

First, we do 7y-4y.

7y-4y = 6

3y = 6

Now, we solve for y.

3y = 6

y = 6/3

y = 2

Final answer:

To solve the equation 7y - 4y = 6 for y, we first simplify the left side to get 3y = 6. Then we divide both sides by 3 to get y = 2.

Explanation:

The given problem is a simple algebraic equation which we need to solve for y. The equation given is 7y - 4y = 6.

First, we simplify the left side of the equation by subtracting the coefficients of y: 7y - 4y equals 3y. So our equation is now 3y = 6.

To get y by itself on the left side of the equation, we need to divide both sides of the equation by 3. This gives us: y = 6/3 .

Therefore, the value of y that satisfies the equation is y = 2.
