Answer:

x=-32/11

Step-by-step explanation:

Let's solve your equation step-by-step.

1/(x+3)=11

(1/n=reciprocal of n)

Step 1: Multiply both sides by x+3.

1=11x+33

11x+33=1(Flip the equation)

11x+33−33=1−33(Subtract 33 from both sides)

11x=−32

11x/11=−32/11

(Divide both sides by 11)

x=−32/11

Check answers. (Plug them in to make sure they work.)

x=−32/11

(Works in original equation)

Find the perimeter of this figure. Please show work. ​
Elena-2011 [213]

Answer:

  40.56 ft

Step-by-step explanation:

The perimeter is the sum of the lengths of the "sides" of this figure. Starting from the left side and working clockwise, the sum is ...

  P = left side (8 ft) + top side (10 ft) + semicircle (1/2×8 ft×π) + bottom side (10 ft)

  = 28 ft + 4π ft

  = (28 +12.56) ft

  P = 40.56 ft

Can anyone help me with dis

Answer:

Slope is 2.

Step-by-step explanation:

So to find slope, we need to take the change in the y value, and the change in the x value, and then divide them. This may be confusing, so here is just 3 formulas in 3 seperate steps that we use to find it:

Step 1 - x_2-x_1=change_.in_.x

Step 2 - y_2-y_1=Change_.in_.y

Step 3 - \frac{Change_. in_. y}{Change_.in_.x}=slope

So lets start by doing step one.

All we need is to look for two x values. Lets use 5 and 6:

6-5=1

So 1 is our change of x. This is our 1st step.

Next we can use 2 y values, note that these should be the 2 y values that go wiht the x values above. So this means we have to use -3 and -1:

-1-(-3) = 2

So 2 is our change in y. This is our 2nd step.

Now lets plug this into:

\frac{Change_. in_. y}{Change_.in_.x}=slope:

\frac{2}{1}  = 2

So our slope is 2. Completing our 3rd and final step.

Hope this helps!
