Which function in vertex form is equivalent to f(x) = x² + x +1?

mylen [45]

Answer:

$\left( x+\frac{1}{2} \right)^{2} + \frac{3}{4}$

Step-by-step explanation:

NOTE :

$x^2+ax=\left( x+\frac{a}{2} \right)^{2} -\left( \frac{a}{2} \right)^{2}$

………………………………………

f(x) = x² + x +1

$=x^{2}+2\times \frac{x}{2} +1$

$=\left( x+\frac{1}{2} \right)^{2} -\left( \frac{1}{2} \right)^{2} +1$

$=\left( x+\frac{1}{2} \right)^{2} - \frac{1}{4}+1$

$=\left( x+\frac{1}{2} \right)^{2} + \frac{3}{4}$

A collection of nickels and quarters are worth $2.85. There are 3 more nickels than quarters. How many nickels and quarters are

Alex777 [14]

Answer:

nickels = 12

quarters = 9

Step-by-step explanation:

Let number of quarters be "q", and

number of nickels be "n"

Nickels are worth $0.05 and Quarters are worth $0.25

Since all of them are worth 2.85, we can write:

0.25q + 0.05n = 2.85

Also, we know, there are 3 more nickels than quarters, so we can write:

n = 3 + q

Now, we can substitute equation 2 into equation 1 to get:

$0.25q + 0.05n = 2.85\\0.25q + 0.05(3+q) = 2.85\\0.25q+0.15+0.05q=2.85$

Now, we solve for q:

$0.25q+0.15+0.05q=2.85\\0.3q=2.70\\q=9$

There are 9 quarters.

We know n = 3 + q

So,

n = 3 + 9

n = 12

There are 12 nickels
