Answer:

a = 1/2b

b = 2a

Step-by-step explanation:

-3a + 6b = a + 4b

Add -a and -6b on both sides.

-3a - a = 4b - 6b

-4a = -2b

Divide both sides by -4.

a = -2/-4b

a = 1/2b

To find b, multiply both sides by 2.

2a = b

Solve the equation for y:<br> 3 + 5y/2<br> = X
pychu [463]

Answer :

y = \frac{2}{5} ( x - 3)

Step-by-step explanation:

6 + 5y = 2x

or, 5y + 6 - 6 = 2x - 6

or, 5y = 2x - 6

or, 5/5 y = 2 ( x - 3) / 5

or, y = 2/5 ( x - 3)

therefore, y = \frac{2}{5} ( x - 3 )

Solve the equation 6(x + 2) = 3(2x + 4).How many solutions are there? Show your work ​
Naily [24]
6(x + 2) = 3(2x + 4)
STEP ONE:
Multiply both sides
6x + 12 = 6x + 12
STEP TWO:
You can see both sides are identical, therefore you can conclude there are infinite solutions

Use the laws of sine and cosine to find the missing Dimension part 3
BigorU [14]

9514 1404 393

Answer:

  12 or 103

Step-by-step explanation:

The given angle is opposite the shorter side, so there will be two solutions.

In order to find f, we need to know angle F. We can find that by first finding angle E.

  E = arcsin(e/d·sin(D)) = arcsin(71/62·sin(36°)) = 42.307° or 137.693°

  F = 180° -D -E = 180° -36° -{42.307°, 137.693°} = {101.693°, 6.307°}

Then the measure of f is ...

  f = sin(F)/sin(D)×d = 62/sin(36°)×sin({101.693°, 6.307°})

  f = {103.29, 11.59}

Side f is either 12 or 103.

If u put 2500 in an account at an annual rate of 5.6 with interest compounded annually, what is annual percentage yield
Alexus [3.1K]

Answer:

5.6%

Step-by-step explanation:

The computation of the annual percentage yield is shown below:

Given that

Initial investment amount is 2,500

And, there is an annual rate of interest i.e. 5.6%

Since we have to determine the annual percentage yield i.e. equivalent to the annual rate of interest i.e. 5.6%

Hence, the above represent the answer
