Identify the zero that has a multiplicity greater than one:
f(x) = (x - 2)(x + 2)(x – 5)

answer:

2(multiplicity 2)

step-by-step explanation:

2 is repeated twice in the function.

answer:

step-by-step explanation:

all real numbers are solutions in both.

12(x2−x−1)+13(x2−x−1)=25(x2−x−1)

step 1: simplify both sides of the equation.

25x2−25x−25=25x2−25x−25

step 2: subtract 25x^2 from both sides.

25x2−25x−25−25x2=25x2−25x−25−25x2

−25x−25=−25x−25

step 3: add 25x to both sides.

−25x−25+25x=−25x−25+25x

−25=−25

step 4: add 25 to both sides.

−25+25=−25+25

0=0

answer:

y= 1/3 x +5

step-by-step explanation:

to find the slope, we take two points

(0,5)   and (15,10)

the slope is found by the formula

m = (y2-y1)/ (x2-x1)

    = (10-5)/(15-0)

    = 5/15

    = 1/3

the slope is 1/3

the y intercept is found when x=0

when x=0   y=5

the slope intercept form of the line is

y=mx+b   where m is the slope and b is the y intercept

y= 1/3 x +5
