Rasek [7]

Answer:

B. 1

Step-by-step explanation:

Multiply the first term by $x^a$ , the second term by $x^b$ , the third term by $x^c$ .

The first term becomes:

$x^a/(x^a+x^b+x^c)$

The second term becomes:

$x^b/(x^a+x^b+x^c)$

The third term becomes:

$x^c/(x^a+x^b+x^c)$

Their sum is:

$(x^a+x^b+x^c)/(x^a+x^b+x^c) = 1$

Correct choice is B

You are walking along a path y= 2x + 12 and your

UNO [17]

Answer:

(-1,10)

Step-by-step explanation:

At the point when the paths cross, the respective x and y values of each equation will be equal.

Your path is y=2x+12, and your friends path is 4x+y=6. Sub 2x+12 in for y (from your path's equation) into your friends equation to find the value of x:

4x+2x+12=6

6x=-6

x=-1

y=2x+12

y=2(-1)+12=10

So you will cross paths at (-1,10)
