Answer:

a = - \frac{9}{2} , b = - \frac{25}{4}

Step-by-step explanation:

To obtain the required form use the method of completing the square

add/ subtract ( half the coefficient of the x- term)² to x² - 9x

y = x² + 2(- \frac{9}{2} )x + \frac{81}{4} - \frac{81}{4} + 14

  = (x - \frac{9}{2} )² - \frac{81}{4} + \frac{56}{4}

  = (x - \frac{9}{2} )²- \frac{25}{4} ← in the form (x + a)² + b

with a = - \frac{9}{2} and b = - \frac{25}{4}

Barbara was earning $8.70 per hour when she got a 6% increase in pay .what was the rate of pay after that increase ?
densk [106]
First we find the increase by multiplying the percentage with the base salary

8.70*(6/100)=0.522 that's the increase

then we add it to the base salary

8.70+0.522=9.222$
