y2-3x2+6x+6y= 18 is in standard form.
The vertex form would be (y+3)2/24 - (x-1)2/8 = 1

The 'answer' is the number that 'c' must be, if 5c is really the same as -75.In order to find out what number that is, you could use 'algebra'.First, write the equation, so that you can look at it:5c = -75Now, use the law of algebra that says: "If equals are divided by equals,then the quotients are equal".The left and right sides of your equation are equals. Divide them both by 5,and that law says that the quotients on both sides will be equal:c = -15
That's not an equation, it doesn't ask a question, and there's nothing about it that needs an answer. It's an "expression". Its value depends on the value of 'x', and every different value for 'x' gives the expression a different value. If you want to write an equation ... that asks a question ... it needs an 'equals' sign ( " = " ) in it somewhere.
y = 2x2 + 3x + 6 Since a > 0 (a = 2, b = 3, c = 6) the graph opens upward. The coordinates of the vertex are (-b/2a, f(-b/2a)) = (- 0.75, 4.875). The equation of the axis of symmetry is x = -0.75.
7x + 4 = 2x + 5Subtract 4 from each side of the equation:7x = 2x + 1Subtract 2x from each side:5x = 1Divide each side by 5:x = 1/5 = 0.2
To write the equation ( y = -7x + 6 ) in standard form, you need to rearrange it into the format ( Ax + By = C ). Start by adding ( 7x ) to both sides to get ( 7x + y = 6 ). In standard form, ( A ), ( B ), and ( C ) should be integers, so the final equation is ( 7x + y = 6 ).
