Red =18
blue=48
green=12
orange=?
red/blue =green/orange
so 18/48=12/orange
let orange = X and solve the equation

Find the indicated limit, if it exists. limit of f of x as x approaches 9 where f of x equals x plus 9 when x is less than 9 and
SVEN [57.7K]

Answer:

B. 18

Step-by-step explanation:

For the function

f(x)=\left\{\begin{array}{l}x+9,\ \ x

we can find the value of the function for all x that are very close to 9 but are less than 9 and for all values of x that are very close to 9 but are greater than 9.

1. For x

\lim \limits_{x\rightarrow 9}f(x)=\lim \limits_{x\rightarrow 9}(x+9)=9+9=18

2. For x\ge 9:

\lim \limits_{x\rightarrow 9}f(x)=\lim \limits_{x\rightarrow 9}(27-x)=27-9=18

So, limit exists and is equal to 18.

Answer:

  • $9 and $7

Step-by-step explanation:

<u>The first equation:</u>

  • x + 2y = 23

<u>The second equation:</u>

  • 2x + 3y = 39

<u>Convert to slope-intercept form:</u>

  • x + 2y = 23 ⇒ 2y = -x + 23 ⇒ y = -1/2x + 11.5
  • 2x + 3y = 39 ⇒ 3y = -2x + 39 ⇒ y = -2/3x + 13

<em>The graph is attached</em>

<u>Intersection point is (9, 7)</u>
