The value of the angle shown in the protactor is 50° and the value of y is 10°.

<h3>How to calculate the values?</h3>

The value of y will be:

2y + 30 = 3y + 20

3y - 2y = 30 - 20

y = 10

The value of x when they're complementary will be:

5x - 2 + 3x + 4 = 90

8x + 2 = 90

8x = 90 - 2

8x = 88.

x = 88/8 = 12

The value of angle FDE will be:

3x + 10 + 6x + 8 = 180

9x + 18 = 180

9x = 180 - 18

9x = 162

x = 162/9

x = 18

FDE = 6x + 8

= 6(18) + 8

= 108 + 8

= 116

Given that (6,-8) is on graph f(x), find the corresponding point for the function f(-1/2x)
ValentinkaMS [17]
Set the argument -1/2x equal to the x coordinate of the given point 6. Solve for x

-1/2x = 6
x = 6(-2)
x = -12

So x = -12 makes the equation -1/2x = 6 true. 

If we plug x = -12 into f(-1/2x) we get f(6)

Since we know that (6,-8) is on the graph of f(x), we know that (-12,-8) is on the graph of f(-1/2x)

What happens is that there's a reflection over the y axis (due to the minus sign in -1/2x) and there's a horizontal stretch by a factor of 2. So the graph of f(-1/2x) appears to be wider than f(x).

In summary, the final answer is (-12,-8)

a rectangle has an area of 320 feet squared. the length is 4 feet longer than the width. find the dimensions.
deff fn [24]

Width of the rectangle is 16 ft and length of the rectangle is 20 ft

<u>Step-by-step explanation:</u>

Step 1:

Given area of the rectangle = 320 ft². Let the width of the rectangle be x, then the length = x + 4. Use the formula for area of a rectangle = (length × width)

320 = x(x + 4)

320 = x² + 4x

x² + 4x - 320 = 0

x = (-b ±√b² - 4ac)/2a = (-4 ±√16 - 4×1×-320)/2

  = (-4±√1296)/2 = (-4 ± 36)/2

  = 32/2, -40/2 = 16, -20 (neglecting the negative value)

∴ Width of the rectangle = 16 ft

∴ Length of the rectangle = 16 + 4 = 20ft
