So for this question (for finding x and y) you will want to use elimination. To do this you will need to bring the x and y to the same side (I put them on the left):
-3/2x+y=6
x+y=0
Now subtract the y on the bottom from the top to isolate x:
3/2x=6
Now the easiest way to bring over the 3/2 to isolate the x fully is to convert it to decimal (1.5) and divide it by 6 (because when multiplication on one side of problem the only way to bring it over is to divide):
x=6/1.5
which simplifies to:
x=4
Hope this helps!

Estimate the perimeter and the area of the shaded figure to the nearest whole number.

soldier1979 [14.2K]

Answer:

Step-by-step explanation:

The area and perimeter of the given shaded figure are respectively 33.12 unit² and 20.56 units.

Area and perimeter-based problem:

What information do we have?

Radius of semi-circle = 8 / 2 = 4 unit

Length of remain Rectangle = 8 unit

Width of remain Rectangle = 2 unit

Perimeter of shaded figure = πr + (l + 2b)

Perimeter of shaded figure = (3.14)(4) + [4 + (2)(2)]

Perimeter of shaded figure = 12.56 + 4 + 4

Perimeter of shaded figure = 20.56 units

Area of shaded figure = πr²/2 + lb/2

Area of shaded figure = (3.14)(4)²/2 + (8)(2)/2

Area of shaded figure = (3.14)(8) + 8

Area of shaded figure = 25.12 + 8

Area of shaded figure = 33.12 unit²

Which of the following describes the graph of y=\sqrt(-4x-36) compared to the parent square root function?

borishaifa [10]

Answer:

Option D - Stretched by a factor of 2, reflected over the y-axis, and translated 9 units left.

Step-by-step explanation:

Given : The function $y=\sqrt{-4x-36}$

To find : Which of the following describes the graph of $y=\sqrt{-4x-36}$ compared to the parent square root function?

Solution :

First we simplify the given expression

$y=\sqrt{-4x-36}$

$y=\sqrt{4(-x-9)}$

$y=2\sqrt{-(x+9)}$

→When we see the original square root function minus was taken outside x and 9 was added from x and 2 was multiplied to the entire function.

Multiplying 2 in the function will give you the stretched by a factor of 2.

$g(x)=\sqrt{-x}$ shows the reflection about y-axis i.e, (x,y)→(-x,y).

If f(x)→f(x+b) then function is shifted left by unit b

⇒ g(x))→g(x+9) then function is shifted left by unit 9

Therefore, The graph of was stretched by a factor of 2, reflected over the y-axis, and translated 9 units left to obtain the graph of the function .

So, Option D is correct.
