When subtracting a negative and a positive your answer would be a positive?
If you are subtracting the negative from the positive, the answer will be positive. If you are subtracting the positive from the negative, the answer will be negative.
When you multiply a positive number by a negative by a negative one what is the sign of the answer?
A negative times a positive is a negative and that negative times a negative would = a positive. So the answer would be a positive number. *<:)
Would a positive multiplied by a negative be a positive?
No. A positive times a negative is always negative. A negative times a negative is always a positive.
What would be the answer to positive 3 times negative 4?
A positive times a negative is negative, so positive 3 times negative 4 would be negative 12.
How would you use the distance formula and the slope formula to prove that this figure is actually a rectangle?
You would first prove that 3 of the sides are the same size (The 4th is automatically the same size as the other three). Then, you would prove that there are three right angles in the shape, using the slopes (If lines make a right angle, they are perpendicular and their slopes are negative reciprocals of each other.).
How do you prove a right angle using coordinate geometry?
Right angles are created by perpendicular lines. You first have to find the slopes of the lines. You know lines are perpendicular when the slopes are negative reciprocals. For example: If you find the slope of Line AB to be -2, in order for the lines to form right angles, the following line would have to be 1/2. So getting back to your question, calculate the slopes and show they are negative reciprocals. Hope I Helped!
Two lines are perpendicular If one line has a slope of 1 over 21 what is the slope of the other line?
When two lines are perpendicular, their slopes are negative reciprocals. In the example, the perpendicular to y= (1/21) x would be y = -21 x For y = 2x, the perpendicular would be y= -½ x You invert the fraction and change the sign.
What kind of slopes do perpendicular lines have?
The slopes of perpendicular lines are reciprocals of each other. For example. if one line had an equation like y= 2x+4 then the perpendicular's slope would be y=x/2+4 -- they are reciprocals of each other.
Are two lines with different slopes perpendicular?
Only by coincidence. Two lines on a graph are perpendicular if and only if one slope is the negative reciprocal of the other: meaning that if one line has a slope of 3/2, the other would have to have a gradient of -2/3.
When subtracting a negative and a positive your answer would be a positive?
If you are subtracting the negative from the positive, the answer will be positive. If you are subtracting the positive from the negative, the answer will be negative.
When you multiply a positive number by a negative by a negative one what is the sign of the answer?
A negative times a positive is a negative and that negative times a negative would = a positive. So the answer would be a positive number. *<:)
If a is a negative number what would -a be?
If a i positive, -a is negative; if a is negative, -a is positive.
Would a positive multiplied by a negative be a positive?
No. A positive times a negative is always negative. A negative times a negative is always a positive.
Which figure contains a pair of perpendicular line segments?
Two ways to determine if two line segments are perpendicular:1. Determine the angle formed: if the angle made by the two line segments is 90 degrees, then they are perpendicular. This can sometimes be done visually if the graph has grids, but probably not what the question is asking you to do.2. Compare slopes*: if the slopes are negative inverses of each other, they are perpendicular. For example, if the slope of one line is 5, the slope for the other line would need to be -1/5, or -0.2. An easy way to remember, is if the product of the two slopes is -1, they are perpendicular.*Side note: slope is "rise over run", or change in y divided by change in x

Is a negative a positive is what?
A Negative plus a positive = a negative because negative and a positive cannot work together Negative + Negative= Positive Positive + Positive = Positive when your dealing with numbers such as : -2 + 2 would equal a negative 4 -2 +-2 would equal a positive 4
