125% because sixteen is equal to a whole which is equal to one-hundered and one fourth of sixteen is four and sixteen plus four is twenty. one fourth of one-hundered is twenty-five so you add the twenty-five to the one-hundered and you get 125%

Point G is between F and H. FH= 102, FG=5x+9, and HG=9x-5

dexar [7]

FH = 102, FG = 5x + 9. HG = 9x - 5 Given

FG + HG = FH Segment addition postulate

5x + 9 + 9x - 5 = 102 Substitution

14x + 4 = 102 Simplify (added like terms)

14x = 98 Subtraction property of equality

x = 7 Division property of equality

b) FG = 5x + 9 = 5(7) + 9 = 35 + 9 = 44

c) HG = 9x - 5 = 9(7) - 5 = 63 - 5 = 58

Answers: a = 7, b = 44, c = 58

What are the zeros of the polynomial function? f(x)=x2−12x+20 Enter your answers in the boxes. The zeros of f(x) are and

Schach [20]

$f(x)=x^{2} -12x+20$
$f(x)=0$
x $x^{2} -12x+20=0$
Factoring:
$(x-2)(x-10)=0$
Two possible soolutions:

$x-2=0 [tex]x=2$

$x-10=0$
$x=10$

The zeros of the polynomial function are x=2 and x=10
