Which of the following linear relationships is NOT also a proportional relationship?
katen-ka-za [31]

The linear relationships that are proportional relationship are y = (-2)x , y = (3/5)x  , y = - (1/2)x  .

A linear relationship in the form of y = mx + c is said to be a proportional relationship when c = 0  .

in the question

Part(a)

the equation is  y = (2)x - 3

on comparing it with y = mx + c , we get c = -3 , which is not 0 .

So , it is not a proportional relationship .

Part(b)

the equation is  y = (-2)x

on comparing it with y = mx + c , we get c = 0 ,

So , it is a proportional relationship .

Part(c)

the equation is  y = (3/5)x

on comparing it with y = mx + c , we get c = 0 ,

So , it is a proportional relationship .

Part(d)

the equation is  y = - (1/2)x

on comparing it with y = mx + c , we get c = 0 ,

So , it is a proportional relationship .

Therefore, The linear relationships that are proportional relationship are y = (-2)x , y = (3/5)x  , y = - (1/2)x  , that are options (b) , (c) and (d) .

The given question is incomplete , the complete question is

Which of the following linear relationships is NOT also a proportional relationship?

(a) y = (2)x - 3

(b) y = (-2)x

(c) y = (3/5)x

(d) y = - (1/2)x

Use the Quadratic Formula to solve the equation. (Enter your answers as a comma-separated list.) 13x^2 +1 = -10
12345 [234]

Step-by-step explanation:

The given quadratic equation is :

13x^2 +1 = -10x\\\\or\\\\13x^2+10x+1=0

The formula to solve a quadratic equation is :

x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}

Put a = 13, b = 10 and c = 1

So,

x=\dfrac{-10\pm \sqrt{10^2-4(13)(1)} }{2(13)}\\\\x=-0.118, -0.651

Hence, this is the required solution.

sergey [27]

The equivalent expression is option A) 12(l+2a)

<u>Step-by-step explanation</u>:

  • The expression for total cost = 12l+24a
  • Taking 12 as common from all the terms in the expression,

we get, 12 (l+2a)

Therefore, The equivalent expression of 12l+24a is 12(l+2a).
