Answer: confirm and final answer is 3:11:3

Step-by-step explanation:

39: 143: 39

all 3 will be divided by 13 like:              

39/ (/ is for dividing sign) by 13= 3

143/ by 13= 11

39/ by 13= 3

so in this way the answer is 3: 11: 3

Is change in math always represented as a positive number even when its negative?
beks73 [17]
I think you mean like a number decreasing at a percentage. Yea it’s gonna be positive cause like it’s a number but then it’s probably gonna say decreasing making it negative or increasing making it positive. I’m pretty sure, correct if I’m wrong.

SHORT ANSWER Graph and label point W(4, –1) <br> on the coordinate plane.
Lunna [17]

Answer:

Step-by-step explanation:

a coordinate point is (x, y) so for point W (4, -1),  4 is the x-coordinate and -1 is the y-coordinate.

Start at the origin (O).  Go 4 units to the right (along the x-axis in a positive direction) and then 1 unit down (in the y plane in a negative direction).

plain why the function is discontinuous at the given number a. (Select all that apply.) f(x) = x2 − 2x x2 − 4 if x ≠ 2 1 if x =
ElenaW [278]

Answer with Step-by-step explanation:

We are given that

f(x)=\left\{\begin{matrix}\dfrac{x^2-2x}{x^2-4}&,if\ \ x\neq 2 \\ 1&,if\ \ x=2\end{matrix}\right.

We have to explain that why the function is discontinuous at x=2

We know that if function is continuous at x=a then LHL=RHL=f(a).

f(x)=\frac{x(x-2)}{(x+2)(x-2)}=\frac{x}{x+2}

LHL=Left hand limit when x <2

Substitute x=2-h

where h is small positive value >0

\lim_{h\rightarrow 0}f(x)=\lim_{h\rightarrow 0}\frac{2-h}{2-h+2}

\lim_{h\rightarrow 0}\frac{2-h}{4-h}=\frac{2}{4}=\frac{1}{2}

Right hand limit =RHL when x> 2

Substitute

x=2+h

\lim_{h\rightarrow 0}f(x)=\lim_{h\rightarrow 0}\frac{2+h}{2+h+2}=\lim_{h\rightarrow 0}\frac{2+h}{4+h}

=\frac{2}{4}=\frac{1}{2}

LHL=RHL=\frac{1}{2}

f(2)=1

LHL=RHL\neq f(2)

Hence, function is discontinuous at x=2
