Given that 7x – 2y = 30
weeeeeb [17]

Answer:

x=32/7

Step-by-step explanation:

7x-2(1)=30  Plug in 1 as y and simplify.

7x-2=30     Add 2 on both sides of the equation.

  <u>+2 +2</u>

7x=32         Divide both sides of the equation by 7.

<u>/7   /7</u>

x=32/7

According to the rational root theron what are all the potential roots of f(x)=9x^4-2x^2-3x+4
Viefleur [7K]

Answer:

<u>Potential roots:</u>  \frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1

Step-by-step explanation:

Simply put, the rational roots theorem tells us that if there are any rational roots of a polynomial function, they must be in the form

±  \frac{FactorsOfa_{0}}{FactorsOfa_n}

Where

a_n is the number before the highest power of the polynomial, and

a_0 is the constant in the polynomial

<em>From the polynomial shown, we have a_n = 9 and a_0 = 4</em>

<em />

<em>The factors of 9 are 9, 3, 1</em>

<em>and</em>

<em>The factors of 4 are 4,2,1</em>

<em />

So, if there are any rational roots, they would be:

±  \frac{FactorsOfa_{0}}{FactorsOfa_n}

±  \frac{9,3,1}{4,2,1}

Which is  ±   9/4, 9/2, 9/1, 3/4, 3/2, 3/1, 1/4, 1/2, 1/1

or

\frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1
