A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the answer for construct a line through X parallel to AB in geometric constructions?

answerDraw two lines of equal lengths perpendicular to AB on the same side of AB and extend the line formed by joining the two end points of the two perpendicular lines which does not line on the line AB.


Find slope of the line ab?

If point a has coordinates (x1,y1), and point b has coordinates (x2, y2), then the slope of the line is given by the formula: m = (y2-y1)/(x2-x1).


How similar triangles can be used to prove that the slope is the same between any two distinct points on a non-vertical line?

Let A, B, C and D be any four points on a non-vertical straight line. Suppose the vertical line from B meets the horizontal line from A at P, and the vertical line from C meets the horizontal line from D at Q. Now, AP and CQ are both horizontal so they are parallel and AC is an intercept. Therefore the corresponding angles BAP and DCQ are equal. BP and DQ are both vertical so they are parallel and BD is an intercept. Therefore the corresponding angles ABP and CDQ are equal. AP and CQ are both horizontal and BP and DQ so that angle APB = angle CQD = 90 degrees. Thus the corresponding angles of triangle ABP are congruent to those of triangle CDQ. Therefore the ratios of their sides is the same. AB/CD = AP/CQ = BP/DQ. In particular, AP/CQ = BP/DQ. By cross multiplication, BP/AP = DQ/CQ or, slope calculated from AB = slope calculated from CD.


Explain why Ab and Ba are the same line but Cd and Dc are not not the same ray?

Ab and Ba are the same line because there are no endpoints to a line. Therefore, you can reverse the order of the letters. So, Cd and Dc are not the same ray because the first letter is the endpoint. So on ray Cd, point C is the endpoint and d is a point on the line coming from the endpoint. On ray Dc, D is the endpoint.


Can you draw a label line ab using a straightedge?

Draw and label line Ab

If AB is parallel to CD and the slope of CD is one over two what is the slope of AB?

The slope of line AB will be 1/2. Two parallel lines will always have the same slope, so if you know the slope of one line that is parallel to another, you know the other line's slope.


Suppose the slope of AB is zero what is the slope of CD given that a. CD is parallel to AB b. CD is perpendicular to AB?

Any line that is parallel to another line will have the same slope. So if line AB's slope is zero and line CD is parallel to AB, then its slope will also be zero. The slope of line CD, when perpendicular to AB, will be infinity. If line AB has a slope of zero that means its just a horizontal line passing some point on the y-axis. A line that is perpendicualr to this one will pass through some point on the x-axis and therefore have an infinite slope.


If AB is parallel to CD and the slope of CD is -8 what is the slope of AB?

If the lines AB and CD are parallel then they both will have the same slope of -8 but with different y intercepts


Slope of a line AB is 4 what is the slope of CD if CD is perpendicular to AB?

Slope of perpendicular line is the negative reciprocal. So it is -1/4


Which property is illustrated by the statement AB equals CD so AB plus DE equals CD plus DE?

It is the additive property of equality, as the additive property of length, as applied to adjacent or parallel line segments.


How many lines parallel to AB contain B?

Every line that's exactly on the AB line.


How do you write intersecting lines?

If line AB contains the points 4 19 and -3 5 what is the slope of a line perpendicular to AB?

-1/2 or -0.50


If AB contains the points 6 -2 and -3 16 what is the slope of a line perpendicular to AB?

0.5

In trapezium ABC AB and DC are parallel sides and AB equal 5cm CD equal 7.5cm and AB equal 6cm Draw BX parallel AD to cut CD at X Find angle BCX and BD?

The question cannot be answered since it is inconsistent. It first states that AB equals 5 cm and then AB equals 6 cm. Please check your typing and resubmit.


What does it mean for something to be perpendicular?

For two items (Planes, lines, line segments, ect.) to be perpendicular that means that they meet at a 90 degree angle. Perpendicularity is denoted by the ⊥ symbol. For example line AB ⊥ line CD would mean that the line AB would be perpendicular to the line CD.
