The first thing we must do in this case is to solve both inequations.
 We have then:
 Inequality 1:
 6 -2x <12
 6-12 <2x
 -6 <2x
 -6/2 <x
 -3 <x
 Inequality 2:
 7 + 2x <-11
 2x <-11-7
 2x <-18
 x <-18/2
 x <-9
 Answer:
 
(-inf, -9) U (-3, inf)

Someone pls answer this it’s so confusing lol

Answer:

<h2>y = \frac{w}{h -  {2c}^{3} }</h2>

Step-by-step explanation:

w = yh - 2yc³

First of all factorize y out of the expression on the right side of the equation

That's

w = y( h - 2c³)

Next divide both sides by (h - 2c³) to make y stand alone

We have

<h3>\frac{y(h -  {2c}^{3}) }{h -  {2c}^{3} }  =  \frac{w}{h -  {2c}^{3} }</h3>

We have the final answer as

<h3>y = \frac{w}{h -  {2c}^{3} }</h3>

Hope this helps you

. The function s(l) = 1.34 √l models the maximum speed s in knots for a sailboat with length l in feet at the waterline. a. Use
trasher [3.6K]

Answer:

The length of the sailboat is 80 feet.

Step-by-step explanation:

The function  

s(l) = 1.34 \sqrt{l} ................ (1)  

models the maximum speed s in knots for a sailboat with length l in feet at the waterline.

So, using this model we have to find the length of a sailboat with a maximum speed of 12 knots.

Now, from equation (1) we get

12 = 1.34 \sqrt{l}

⇒ \sqrt{l} = 8.955

⇒ l = (8.955)^{2}  = 80 feet (Answer)

{The value is round to the nearest foot}
