Solve the equation for x 2/3x-1/9x + 5 = 20

Nady [450]

$\bold{Answer}$

$\boxed{\bold{X \ = \ 27}}$

$\bold{Explanation}$

$\bold{Solve: \ \frac{2}{3}x-\frac{1}{9}x+5=20}$

$\bold{--------------------------}$

$\bold{Subtract \ 5 \ From \ Both \ Sides}$

$\bold{\frac{2}{3}x-\frac{1}{9}x+5-5=20-5}$

$\bold{Simplify}$

$\bold{\frac{2}{3}x-\frac{1}{9}x=15}$

$\bold{Multiply \ By \ LCM: \ LCM \ = \ 9}$

$\bold{\frac{2}{3}x\cdot \:9-\frac{1}{9}x\cdot \:9=15\cdot \:9}$

$\bold{Simplify}$

$\bold{6x-x=135}$

$\bold{5x=135}$

$\bold{Divide \ Both \ Sides \ By \ 5}$

$\bold{\frac{5x}{5}=\frac{135}{5}}$

$\bold{Simplify}$

$\bold{X \ = \ 27}$

$\boxed{\bold{Eclipsed}}$

f(x) = 4x^2+2x+6 What is the value of the discriminant of f? How many distinct real number zeros does f have?

Sauron [17]

Answer:

The value of Discriminant of the function is -92

It has ZERO distinct real number zeros.

Step-by-step explanation:

Given:

$f(x)=4x^{2} +2x+6$

Which is a Quadratic Equation in the general form of

$ax^{2}+bx+c=0$

where a,b and c are constants.So on comparing the given equation with general form we get,

$a=4\\b=2\\c=6$

Formula for discriminant we have

$Discriminant=b^{2}-4ac\\ =2^{2}-4(4)(6)\\ =4-96\\=-92$

now for zeros we have

$x=\frac{-b+\sqrt{b^{2-4ac} } }{2a} \\or\\x=\frac{-b-\sqrt{b^{2-4ac} } }{2a} \\$

on substituting these values we get

$x=\frac{-2+\sqrt{-92} }{8}$

or

$x=\frac{-2-\sqrt{-92} }{8}$

the term $\sqrt{-92}$ is imaginary

hence the zeros are not real number

Write the compound statement "I'll exercise if I don't eat too much" in symbols.Let p = "I eat too much"q = "I'll exercise"A. ~p

butalik [34]

We can begin by rewriting the sentence in a more convenient way:

"If I don't eat too much, I'll exercise."

The phrase speaks about an action (exercise) that is going to be done provided a condition is fulfilled (don't eat too much) This is a conditional.

p = I eat too much

~p = I don't eat too much.

Then, if ~p happens, then q will happen

We can write this as

~p->q

With this, the correct answer is option D.
