If x=-1\3 is a zero of a polynomial p(x)=27xcube -axsquare -x+3 then find the value of a

antoniya [11.8K]

Answer:

a = 21

Step-by-step explanation:

If x = h is a zero of a polynomial then f(h) = 0, thus

p(- $\frac{1}{3}$ ) = 27( - $\frac{1}{3}$ )³ - a(- $\frac{1}{3}$ ) - (- $\frac{1}{3}$ ) + 3 = 0, that is

27 (- $\frac{1}{27}$ ) - $\frac{1}{9}$ a + $\frac{1}{3}$ + 3 = 0

- 1 - $\frac{1}{9}$ a + $\frac{10}{3}$ = 0 ( multiply through by 9 to clear the fractions )

- 9 - a + 30 = 0

- a + 21 = 0 ( subtract 21 from both sides )

- a = - 21 ( multiply both sides by - 1 )

a = 21

What is 2/3x=2y+6 in ax+by=c form?

kifflom [539]

Answer:

2x - 6y = 18

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

$\frac{2}{3}$ x = 2y + 6

Multiply through by 3 to clear the fraction

2x = 6y + 18 ( subtract 6y from both sides )

2x - 6y = 18 ← in standard form
