- How do you solve the system x – y = –3 and x - Socratic
There is no solution The two lines will never intersect Write each equation in the form y = mx + c y = x + 3 and y = x - 4 To find the solution graphically each line can be drawn and the point of intersection will give the solution However in this case the lines are parallel because they have the same gradient and as a result they will never intersect There is no solution Algebraically: x
- Question #32068 - Socratic
Going in opposite directions in a parallel line Think of the boats as parallel lines We know that parallel lines never intersect, by definition That means, the boats will have to go in opposite directions in order to be moving toward one another, but they will never "hit" each other If Boat 1 is on the line AB and boat 2 is on the line CD, then 1 has to move towards A and B has to move
- Line QR contains (2, 8) and (3, 10) Line ST contains points . . . - Socratic
Lines are parallel For finding whether lines QR and ST are parallel or perpendicular, what we need is ti find their slopes If slopes are equal , lines are parallel and if product of slopes is -1, they are perpendicular The slope of a line joining points (x_1,y_1) and x_2,y_2) is (y_2-y_1) (x_2-x_1)
- A line passes through (9 ,5 ) and (2 ,8 ). A second line passes through . . .
(0,6) The line passing through (9,5) and (2,8) has a gradient of -3 7 The difference in the y values of the two points divided by the difference in the x values The general equation of a line is y=mx+c where m is the gradient and c is the y intercept So the equation of the line passing through (7,3) with a gradient of -3 7 is y=-3 7x +c But we know the point (7,3) is on the line so substitute
- How do you write an equation in standard form for a line . . . - Socratic
x=-2 represents a vertical line so that a perpendicular line to it will be a perfectly horizontal line passing through (2,1) A perfectly horizontal line has slope m=0 (it is not increasing nor decreasing) so you can use your relationship: y-y_0=m(x-x_0) with m=0 giving: y-1=0(x-2) So your line has equation: color(red)(y=1)
- Also calculate the charges of each atom - Socratic
They are roughly planar (Granted, the differences in stability are subtle Being within "1 kcal mol" is considered chemical accuracy ) This is because hyperconjugation from an adjacent "C"-"H" bond delocalizes the electron density into the central nonbonding p orbital, whether it is empty (in carbocations) or half-filled (in carboradicals)
- Question #733bf - Socratic
a D; b B; c At A a Equivalence point The equivalence point is the point at which the pH changes most rapidly with the addition of a small amount of base
