The value of x for both angles to be vertically opposite is 27

<h3>Vertical angles</h3>

The measure of vertical angles are equal and they are angles that meet at the point of intersection of two lines.

In order to determine the value of x, we will equate both angles to have;

2x = 54

Divide both sides by 2

2x/2 = 54/2

x = 27

Hence the value of x for both angles to be vertically opposite is 27

JK = 7x + 9<br> JL = 114, and<br> KL = 9x + 9,<br> Find KL.
VikaD [51]

Answer:

KL= 63

Step-by-step explanation:

JK=7x+9 , JL=114 , KL=9x+9 ( if the points are on the same line and point J at the end point and K in the middle)

*J_______________________K___________________________L

JL=JK+KL

114=7x+9+9x+9

114-18=16 x

16x=98

x=98/16=6

KL= 9x+9

KL=9(6)+9

KL= 63

The demand function for a product is modeled by p = 400 − 4x, 0 ≤ x ≤ 100, where p is the price per unit (in dollars) and x is t
lawyer [7]

Answer:

Demand is Elastic when Price > 200 ; Demand is inelastic when Price < 200

Step-by-step explanation:

p = 400 - 4x

4x = 400 - p

x = (400 - p) / 4 → x = 100 - p/4

Elasticity of demand  [ P ed ] = (Δx / Δp) x (p / x)

Δx / Δp  [Differentiating x w.r.t p]  = 0 - 1/4  → = -1/4

P ed =  <u>-1</u> x<u> p </u>

            4   (400 - p)/4

= <u>-1</u> x <u> 4p </u>              = -p / (400-p)

  4   (400 - p)

Price Elasticity of demand : only magnitude is considered, negative sign is ignored (due to negative price demand relationship as per law of demand).

So, Ped = p / (400 - p)

Demand is Elastic when P.ed > 1

p / (400-p)  > 1

p > 400 - p

p + p > 400  → 2p > 400

p > 400 / 2 →  p > 200

Demand is inelastic when P.ed < 1

p / (400-p)  < 1

p < 400 - p

p + p < 400  → 2p < 400

p < 400 / 2 →  p < 200

9y+y combine the like terms to create an equivalent expression
larisa [96]

Answer:

10y

Step-by-step explanation:

9y is equal to y+y+y+y+y+y+y+y+y.

If you add y to that you get (y+y+y+y+y+y+y+y+y)+y, which is equal to 10y.
