If I understood the question correctly that you hab to pic one of the 4 than it’s...
x+2y+6=0
arlik [135]3 years ago
3 0

y=\dfrac{-x-6}{2}\qquad\text{multiply both sides by 2}\\\\2y=-x-6\qquad\text{subtract 2y from both sides}\\\\0=-x-2y-6\\\\\boxed{-x-2y-6=0}\qquad\text{change the signs}\\\\\boxed{x+2y+6=0}

If f(x) = 2x2 + 1, what is f(x) when x = 3? a.1 b.7 c.13 d.19
prohojiy [21]

<u>Answer:</u>

The value of f(x) = 2x^2 + 1 when x=3 is 19, hence the correct option is ‘d’.

<u>Solution:</u>

A two degree polynomial equation is given in the question.

The equation is:

F(x)=2 x^{2}+1

We need <em>to find the value of f(x) when the value of x is 3. </em>

To solve a question like this we have to substitute the given value of x in the given equation and then simplify it.

Now let's substitute the value of x in the given equation.

F(x)=2(3)^{2}+1

First we square the number 3 and then multiply it with 2 and then add 1.

This is done because of the BODMAS rule, in which multiplication is given higher preference as compared to addition.

On solving the equation we get,

F(x)=2×9+1

F(x)=18+1

F(x)=19.

Therefore the value of f(x) when x=3 is 19.

Hence the correct option is ‘d’.

\frac{5}{3}  +  \frac{2}{3}  =  \frac{7}{3}
Because the denominators are same, you can just add the numerators.
