Answer:

Step-by-step explanation:

first, you need to know what standard form is

Ax + By = C

which is basically

number(x) + number(y) = number

to put it simply..

so now we can evaluate the expression (the random mess they gave us)

-5x - 7y + 6 and -4 + 3x

we need to put em together so just toss an equal sign between em

so now we have

-5x - 7y + 6 = -4 + 3x

no combine like terms

-8x - 7y + 6 = -4

-8x - 7y = -10

and thats the answer in standard form

Answer:

x^2-12x+27 =0

Step-by-step explanation:

Given a Parabola that intersects the x-axis at x=3 and x=9.

I presume you want to determine the equation of the parabola.

You can use this form:

Given roots of a parabola, the equation of the parabola is derived using the formula:

x^2-($Sum of Roots)x+Product of Roots =0\\Since roots are 3 and 9, the equation becomes:\\x^2-(3+9)x+(3X9) =0\\x^2-12x+27 =0

The equation of the parabola is:

x^2-12x+27 =0
