Answer:

Step-by-step explanation:

No, because $(x^2-x)/2$ does equal $x^2/2-x/2$ . Honestly, it really depends on the value of x, as it provide whether or not the expression is divisible by 2.

Answer:

Yes

Step-by-step explanation:

There are two cases: Case 1: x is even, so x can be modelled as a generic number 2n, where n is a positive integer. Clearly this product is divisible by two. ... Hence, it is safe to generalise that the term x²-x is divisible by 2 for any positive integer x.

Chetan makes a necklace for his sister. Twelve beads take up 5 inches of string. How many beas fit on 1 foot of string

Setler [38]

Find the amount of beads per inch:
12/5 = 2.4 (this doesn't make sense, but it will)
Now find the total beads on one foot, or 12 inches
2.4 x 12 = 28.8
Since 29 wont fit, 28 will be the largest whole number of beads that can fit on the string

i need to know how to find the x and y intercepts and then graph the linear equation for the problem x+y=2

gizmo_the_mogwai [7]

Answer:

The x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).

Join those two points with a straight line and get the graph.

Step-by-step explanation:

The intercept form of a straight line equation is $\frac{x}{a} + \frac{y}{b} = 1$ , where the x-intercept of the line is at (a,0) and the y-intercept will be at (0,b).
