It's the last choice.  In the top row you have the 1's that are the coefficients on the x and the y, and the solution for that equation is 21; in the second row you have the 5 from the x and the 4 from the y and the solution for that equation which is 20.  I'm more used to writing them down instead of across, but there you have it anyways

Make x the subject of the formula: <br> Y=3x^2+4
Rzqust [24]

Answer:

see explanation

Step-by-step explanation:

given

y = 3x² + 4 ( isolate the term in x by subtracting 4 from both sides )

y - 4 = 3x² ( divide both sides by 3 )

\frac{y-4}{3} = x² ( take the square root of both sides )

\sqrt{\frac{y-4}{3} } = x, or

x = \sqrt{\frac{y-4}{3} }

Answer:

The answer is A.

Step-by-step explanation:

Clearly the y-axis in the following graph or scatter plot represents the Stretch length (in cms) and x-axis denotes the value stretch force (in pounds) i.e. the force applied to the string in pounds.

The number 1 in the equation mean in this context:

That the spring is stretched 1 inch when no force was applied to it.

since the number 1  on the y-axis i.e when x=0 i.e. no force is applied to it.

Hope this helps have a nice day!!!
