Answer:

$-\frac{7}{10}$

Step-by-step explanation:

Given:

$\frac{1}{2}- 1 \frac{1}{5}$

Number line is from range -2 to 2 with all increment of ± $\frac{2}{10}$ on both sides.

Step 1: First we will solve the equation we will get;

$\frac{1}{2}- 1 \frac{1}{5}\\\\\frac{1}{2}- \frac{6}{5}$

Step 2: Now we will try to make the denominator common so we will get;

$\frac{1\times 5}{2\times 5}- \frac{6\times 2}{5\times 2}\\\\\frac{5}{10}- \frac{12}{10}$

Step 3: Now from the number line when we subtract $\frac{12}{10}$

from $\frac{5}{10}$ we get number of spaces left are - 7

Hence now it will become:

$\frac{5}{10}- \frac{12}{10}\\\\\frac{5 -12}{10}\\\\-\frac{7}{10}$

Hence the final Answer is $-\frac{7}{10}$

After transforming f(x) = 2x² +4x + 3 into vertex form, the vertex is easily identifiable. Which ordered pair is the vertex?

jolli1 [7]

The vertex is $(-1,1)$

Explanation:

The equation is $f(x)=2x^{2} +4x+3$

To find the vertex, we need the equation in the form of $f(x)=a (x-h)^{2}+k$

Dividing each term by 2 in the equation $f(x)=2x^{2} +4x+3$

$f(x)=2(x^{2} +2x+\frac{3}{2} )$

Now, completing the square by adding and subtracting 1, we get,

$f(x)=2(x^{2} +2x+1-1+\frac{3}{2} )$

The first three terms can be written as $(x+1)^{2}$ ,

$f(x)=2[(x+1)^{2}+\frac{1}{2} ]$

Multiplying 2 into the bracket, we get,

$f(x)=2(x+1)^{2} +1$

This equation is of the form $f(x)=a (x-h)^{2}+k$

Now, we shall find the vertex $(h,k)$

Thus, $h=-1$ and $k=1$

Thus, the vertex is $(-1,1)$

den301095 [7]

Answer:

$19.11

Step-by-step explanation:

-Given that his regular rate is $12.74/h and that the overtime rate is 1.5 times the regular rate.

#We multiply the regular rate by 1.5 to determine his overtime rate;

$Overtime \ Rate=Regular \ Rate \times 1.5\\\\=12.74\times 1.5\\\\=19.11$

Hence, Randy's overtime rate is $19.11
