Answer:

The constant k is equal to $-(2/3)$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In this problem we have

$4x=-6y$

Isolate the variable y

$y=-(4/6)x$

Simplify

$y=-(2/3)x$

In a direct variation the constant k is equal to the slope of the line

$m=k=-(2/3)$

Which of the following algebraic expressions is not simplified?

Hunter-Best [27]

Answer:

B. $x+2x$

Step-by-step explanation:

we will verify each options

option-A:

we have

$x+1$

we can see that x and 1 are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-B:

we have

$x+2x$

we can see that 2x and x are same type of terms

so, they are like terms

so, we can combine or simplify it

$x+2x=3x$

So, this expression is not in simplest form

this is TRUE

option-C:

we have

$x^2+x$

we can see that x^2 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-D:

we have

$5x^3-x$

we can see that 5x^3 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

The ratio of the measures of the sides of a triangle is 3:4:6, and its perimeter is 104 feet. find the measure of each side of t

zimovet [89]

and plug it back into the original terms each side was labeled as:
S1: 3(8)=24ft
S2: 4(8)=32ft
S3: 6(8)=48ft
To check add all three sides and ensure they total your 104ft perimeter.
24+32+48=104
Don't forget to report your answers with the units of measurement!!

Please help |3r -6| =21

julsineya [31]

3r-6=-21

3r-6+6=-21+6 (Add 6 to both sides...)

3r=-15

r=-5

3r-6=21

3r-6+6=21+6 (Add 6 to both sides...)

3r=27

r=9

r=-5 or r=9
