we know that

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

Verify

A) For the point(10,12)

Find the value of k

k=y/x

substitute

k=12/10=1.2

B) For the point(15,18)

Find the value of k

k=y/x

substitute

k=18/15=1.2

C) For the point(20,24)

Find the value of k

k=y/x

substitute

k=24/20=1.2

so

The value of k is equal to 1.2

The equation of the direct variation is equal to

y=1.2x

therefore

<u>the answer is the option a</u>

yes; y=1.2x

What is the line of SYMMETRY for they PARABLLA who’s equation is y=3x2+24x-1?
Arada [10]

Answer

The line of symmetry x = -4

Step by step explanation

Here we have to use the formula.

The symmetry of a parabola x = -b/2a

Now compare the given equation y = 3x^2 + 24x -1 with the general form y = ax^2 + bx + c and identify the value of "a" and "b"


Here a = 3 and b = 24. Now plug in these values in to the formula to find the line of symmetry.

x = -24/ 2(3)

x = -24/6

x = -4

Therefore, the line of symmetry x = -4.

Thank you.
