Plss help me do this

KATRIN_1 [288]

Answer:

x1 = -5

x2 = 3

Step-by-step explanation:

You have the following equation:

$\frac{6}{x}-\frac{4}{5}=\frac{2x}{5}$ (1)

To find the solutions of the equation (1) you first eliminate the denominators of the equation, by multiplying the m.c.m, which is 5x, as follow:

$30-4x=2x^2$

Next, you write the previous equation in the general form ax^2 +bx+c=0, as follow:

$2x^2+4x-30=0$

Next, you use the quadratic formula to find the solutions:

$x_{1,2}=\frac{-b\pm \sqrt{b^2-4(a)(c)}}{2a}\\\\a=2;\ \ b=4;\ \ c=-30\\\\x_{1,2}=\frac{-4\pm \sqrt{4^2-4(2)(-30)}}{2(2)}\\\\x_{1,2}=\frac{-4\pm16}{4}\\\\x_1=-5\\\\x_2=3$

Then, the solutions for the given equation are x1=-5 and x2=3

What are the points on the graph for the equation y=-1/4x+6

Shalnov [3]

You mean coordinates?
They can be found out by substituting a number in the equation.
After substituting several numbers, we get:
x=4;y=5
x=-4;y=7
x=-2;y=7.5

Which of the following represents the zeros of f(x) = 6x3 − 35x2 + 26x − 5?

Effectus [21]

Given the function:
f(x)=6x³-35x²+26x-5
to get the zeros we need to factorize the polynomial given:
to factorize we look for a number such that when we substitute in the equation we get a zero:
first number is:
x=5
thus:
to get the rest of the number we shall have:
(6x³-35x²+26x-5)÷(x-5)
=(3x-1)(2x-1)
thus the other roots are:
x=1/3 and x=1/2
hence the answer will be:
C. 5, one third, negative one half
