Y = 2x - 8 3x - 2y = 13

SSSSS [86.1K]

Answer:

{x,y} = {3,-2}

Step-by-step explanation:

// Solve equation [1] for the variable y

[1] y = 2x - 8

// Plug this in for variable y in equation [2]

[2] 3x - 2•(2x-8) = 13

[2] -x = -3

// Solve equation [2] for the variable x

[2] x = 3

// By now we know this much :

x = 3

y = 2x-8

// Use the x value to solve for y

y = 2(3)-8 = -2

Solution :

{x,y} = {3,-2}

Match each value with its formula for ABC.

Ivahew [28]

For the triangle ABC use the sine theorem:

$\dfrac{a}{\sin A}= \dfrac{b}{\sin B}= \dfrac{c}{\sin C}$ .

1. From $\dfrac{a}{\sin A}= \dfrac{b}{\sin B}$ you have $\dfrac{a}{b} \cdot \sin B=\sin A$ .

2. From $\dfrac{b}{\sin B}= \dfrac{c}{\sin C}$ you have $\dfrac{b}{c} \cdot \sin C=\sin B$ .

3. From $\dfrac{a}{\sin A}= \dfrac{c}{\sin C}$ you have $\dfrac{c}{a} \cdot \sin A=\sin C$ .

4. From $\dfrac{a}{\sin A}= \dfrac{c}{\sin C}$ you have $\dfrac{\sin A}{\sin C} \cdot c=a$ .

5. From $\dfrac{a}{\sin A}= \dfrac{b}{\sin B}$ you have $\dfrac{\sin B}{\sin A} \cdot a=b$ .

6. From $\dfrac{b}{\sin B}= \dfrac{c}{\sin C}$ you have $\dfrac{\sin C}{\sin B} \cdot b=c$ .

What is the area of the figure

Semenov [28]

Answer:

Area of the figure = 36 in²

Step-by-step explanation:

Area of the given composite figure = Area of the rectangle ABCE - Area of triangle CDE

Area of rectangle ABCE = Length × Width

= AB × AC

= 6 × 8

= 48 in²

Area of triangle CDE = $\frac{1}{2}(\text{Base})\times (\text{Height})$

= $\frac{1}{2}(6)(4)$

= 12 in²

Now area of the composite figure = 48 - 12

= 36 square inch
