This answer is C because when you add all of the similar numbers, it simplifies into the new equation.

Given that f(x)=6x^2-900

scZoUnD [109]

Solution for F(x)=6x^2-900 equation:
Simplifying F(x) = 6x2 + -900 Multiply F * x xF = 6x2 + -900 Reorder the terms: xF = -900 + 6x2 Solving xF = -900 + 6x2 Solving for variable 'x'. Reorder the terms: 900 + xF + -6x2 = -900 + 6x2 + 900 + -6x2 Reorder the terms: 900 + xF + -6x2 = -900 + 900 + 6x2 + -6x2 Combine like terms: -900 + 900 = 0 900 + xF + -6x2 = 0 + 6x2 + -6x2 900 + xF + -6x2 = 6x2 + -6x2 Combine like terms: 6x2 + -6x2 = 0 900 + xF + -6x2 = 0

Answer:

Perpendicular

Step-by-step explanation:

To tell if the lines are perpendicular/parallel, you must look at the slope, but in this case, you must first get y by itself, like so:

3x + 7y = 15

-3x - 3x

___________

7y = -3x + 15

Divide both sides by 7:

y = $\frac{-3}{7}x + \frac{15}{7}$

Now the other equation:

7x - 3y = 6

-7x -7x

_________

-3y = -7x + 6

Divide both sides by -3:

y = $\frac{7}{3} x - 2$

You can see that the lines are perpendicular because the slopes ( $\frac{-3}{7} x$ and $\frac{7}{3}$ ) are opposite reciprocals.
