Write the equation of a piecewise function with a jump discontinuity at x =3. Then, determine which step of the 3-step test for
seraphim [82]

Answer:

Here's a possible example:

Step-by-step explanation:

f(x) =\begin{cases} x & \quad x < 3\\x+3 & \quad x \geq 3\\\end{cases}

Each piece is linear, so the pieces are continuous by themselves.

We need consider only the point at which the pieces meet (x = 3).

\displaystyle \lim_{x \longrightarrow 3^{-}} f(x) = \lim_{x \longrightarrow 3^{-}} x = 3\\\\\displaystyle \lim_{x \longrightarrow 3^{+}} f(x) = \lim_{x \longrightarrow 3^{+}} x+3 = 6\\\\f(3) = x + 3 = 6\\\\\displaystyle \lim_{x \longrightarrow 3^{-}} f(x) \neq f(3)

The left-hand limit does not equal ƒ(x), so there is a jump discontinuity at x =3.

X(5)+2=244<br>help pls<br>(^_^)​
arsen [322]

Simplify both sides of the equation

  • 5x+2=244

Subtract 2 from both sides

  • 5x+2−2=244−2
  • 5x=242

Divide both sides by 5

\frac{5x}{5}  =  \frac{242}{5}

  • Answer

\: x =  \dfrac{242}{5}

OR

\: x =  48.4

Ty received test grades of 82%, 74%, 76%, 76%, and 74%.
Nikitich [7]

Answer:

a) To earn C he needs at least 68 and less than 98

b) No, he couldn't make it.

Step-by-step explanation:

I. His avg value is (382 + x)/6

 I pick a random number and that gave

 (68 => to reach 75) and (98 => to reach 80)  

So that makes he needs at least 68 and less than 98

II. The reason why he cannot make it is

 if 100 is 100%

      =   (100 + 382)/6

      = 80.33 That's impossible to reach 90

Hope that help :)

Hello from MrBillDoesMath!

Answer:   x = 7/10

Discussion:

To eliminate fractions multiply each side by 10:

10 ( 9/5x - 2/5 )  = 10 * ( 8x +3)/10      or

10 * ( 9/5)x - 10 *(2/5)  =   8x + 3  or

9 *2 x - 2*2 = 8x +3   or

18x - 4 = 8x + 3.  Subtract 8x for each side:

18x - 8x - 4 = (8x - 8x) + 3 or

10x -4 =  0x + 3 or

10x -4 = 3 or

10x = 7

x = 7/10




Thank you,

MrB
