To do this, you need to solve either one of the equations for y or x. I'm going to solve for y in the first equation:

6x + 3y = 9

Subtract 6x from both sides:

3y = 9 - 6x

Divide both sides by 3:

y = 3 - 2x

Now that you know what y is equal to, you can substitute it into the second equation:

2x + 3y = 1

2x + 3(3-2x) = 1

Distribute the 3:

2x + 9 - 6x = 1

Combine like terms:

9 - 4x = 1

Subtract 9 from both sides:

-4x = -8

Divide by -4:

x = 2

No substitute this 2 into either one of the equations to get y. I'm going to use the first:

6x + 3y = 9

6(2) + 3y = 9

12 + 3y = 9

Subtract the 12 from both sides:

3y = -3

Divide by 3:

y = -1

ANSWER:

x = 2

y = -1

You can always check by substituting the values into the equations.

*Will give brainiest. Tina invests $1000 in an account that pays an interest rate of 6.75%. A=P(1+r)^t.
bezimeni [28]
A=P(1+r)^t
18600=1000(1+0.0675)^t
18600/1000= (1.0675)^t
18.6= (1.0675)^t
log 18.6 = t log 1.0675

Help! E-learning day. thanks!
N76 [4]
X + y = 38
2x + 5y = 100
Where x is how many 2 pointers there were on the test and y how many 5 pinters there were

Elimination method:
2x + 2y = 76
2x + 5y = 100

2x - 2x + 2y - 5y = 76 - 100
-3y = - 24
y = 8
Apply it to the equation to get x
x + 8 = 38
x = 30
30 two pointers
8 five pointers

Answer:

28. W=20ft

29. -340

30. 56, 57, 58

Step-by-step explanation: For 28

1. A = L*W

2. A = 240

3. 240 = 12*W

4. (240/12) = W

5. 20ft = W

Step-by-step explanation: For 29

X +300 = -40

X = -40 - 300

X = -340

Step-by-step explanation: For 30

171/3 = 57, therefore 57 is the average

56, 57, 58

Simplify 1- cos^2 Θ / cos^2 Θ<br><br> Answers<br><br> sin2 θ<br><br> cos2 θ<br><br> tan2 θ<br><br> 1
Tems11 [23]

Answer:

<h3><u /></h3>

<u>Trigonometric identities</u>

<u />

\large \begin{aligned}\cos^2 \theta + \sin^2 \theta & = 1\\\implies \quad \quad \sin^2 \theta & = 1 - \cos^2 \theta\\\\\tan \theta=\dfrac{\sin \theta}{\cos \theta} \end{aligned}

Therefore, using the <u>identities</u>, the given expression can be <em>simplified</em> as follows:

\large\begin{aligned}\implies \dfrac{1- \cos^2 \theta}{\cos^2 \theta} & = \dfrac{\sin^2 \theta}{\cos^2 \theta}\\\\& = \tan^2 \theta\end{aligned}
