Answer:

Step-by-step explanation:

Simplifying

(9x + 5) + -1(4x + 3) = 0

Reorder the terms:

(5 + 9x) + -1(4x + 3) = 0

Remove parenthesis around (5 + 9x)

5 + 9x + -1(4x + 3) = 0

Reorder the terms:

5 + 9x + -1(3 + 4x) = 0

5 + 9x + (3 * -1 + 4x * -1) = 0

5 + 9x + (-3 + -4x) = 0

Reorder the terms:

5 + -3 + 9x + -4x = 0

Combine like terms: 5 + -3 = 2

2 + 9x + -4x = 0

Combine like terms: 9x + -4x = 5x

2 + 5x = 0

Solving

2 + 5x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -2 + 5x = 0 + -2

Combine like terms: 2 + -2 = 0

0 + 5x = 0 + -2

5x = 0 + -2

Combine like terms: 0 + -2 = -2

5x = -2

Divide each side by '5'.

x = -0.4

Simplifying

x = -0.4

Answer:

x = -122/13 OR 9.3846

Step-by-step explanation:

First, take a look at the second equation. Add 8x to the other side.

-7y= 8x -18

Then, divide by -7 to get a regular "y=" equation.

y= 8/7x -18/7

Move on the the first equation. Let's get "y" by itself. Add 3x to the other side.

y= 3x +15

Considering both equations are equal to Y, set them equal ( except the "y" part )

8/7x - 18/7 = 3x + 15

Multiply all by seven so that there are no fractions.

8x - 18 = 21x + 105

Subtract 8x from both sides.

-17 = 13x + 105

Subtract 105 from both sides.

-122 = 13x

Divide by 13 on both sides.

x = 9.3846

Or if you don't want decimals, just say x = -122/13

Quick Note: I made a mistake. I had looked at the second equation at -18. The answer is incorrect but the method of solving is correct. Also, make sure to plug in the value of x to get Y.

Answer:

104.73cm²

Step-by-step explanation:

AREA OF SEMI CIRCLE

9cm-4cm = 5cm

5cm is the radius of the semi-circle

(πr²)/2 =

25π/2 = 12.5π

AREA OF SQUARE

16cm*9cm = 144cm²

AREA OF THE FIGURE SHOWN

144cm² - 12.5cmπ²

144cm² - 39.27cm² = 104.73cm²
