2. If ¡2x+3 = i, where i = V-1, then which of the

Alexus [3.1K]

I assume you mean the equation

$i^{2x+3} = i$

Since i = √(-1), we have i⁴ = 1 and so i⁵ = i. Then 2x + 3 must be some multiple of 5.

Now just check for which of the given choices that this holds:

x = 16 ⇒ 2x + 3 = 35 (yes)

x = 11 ⇒ 2x + 3 = 25 (yes)

x = 10 ⇒ 2x + 3 = 23 (no)

x = 14 ⇒ 2x + 3 = 31 (no)

What is the slope intercept form of 10x + 2y =8

antoniya [11.8K]

Slope intercept form is: y = mx + b

Isolate the y. First subtract 10x from both sides

10x (-10x) + 2y = 8 (-10x)

2y = -10x + 8

Isolate the y. Divide 2 from both sides and <em>all</em> terms.

(2y)/2 = (-10x + 8)/2

y = -5x + 4

y = -5x + 4 is your slope intercept form answer.

hope this helps

Suppose Evan is trying to build a frame out of popsicle sticks x inches long. The frame will have length (2x – 3) and width of (

erik [133]

Answer:

The correct option is A) 3 square inches; $2x^2-7x+6$ .

Step-by-step explanation:

It is given that the length of the frame is (2x-3) and the width is (x-2)

The area of the rectangle is: $A=l\times w$

Where, A is the area l is the length and w is the width of the rectangle.

Put $l=(2x-3)$ and $w=(x-2)$ in the area of the rectangle.

$A=(2x-3)(x-2)\\A=2x^2-4x-3x+6\\A=2x^2-7x+6$

The area of the frame expressed as a polynomial is $2x^2-7x+6$ .

Now substitute x=3 in $A=2x^2-7x+6$ .

$A=2(3)^2-7(3)+6\\A=18-21+6\\A=3$

The area of the frame is 3 square inches.

Hence, the correct option is A) 3 square inches; $2x^2-7x+6$ .
