Rudik [331]

Answer:

Edie has a better deal since his final price is lower

Step-by-step explanation:

Cousin Edie drank all of Clark's egg nog . Edie finds a coupon for 50 cents off that can only be use at a local grocery store.Clark normally buys his egg nog at the supermarket.

The tax rate at both stores is 2.25%.

Clark buys the egg nog at $5.95 plus tax .

Edie buys the egg nog at $6.35 plus coupon plus tax.

After Edie applies the coupon , the final price is $( 6.35 - 0.50 ) = $5.85

Since the percentage of tax applied is the same, the deal with lower final price is better.

Hence, Edie has a better deal.

X^2-x+2=0 Please use the quadratic formula

Ainat [17]

Answer:

$\boxed{\sf x=\cfrac{1\pm \sqrt{-7} }{2}}$

Step-by-step explanation:

$\sf x^2-x+2=0$

Use quadratic formula:

$\boxed{\sf \frac{-b\pm \sqrt{b^2-4ac}}{2a}}$

$\sf a=1, b=-1, c=2$

___________________________

$\sf x_1,_2=\cfrac{-\left(-1\right)\pm \sqrt{\left(-1\right)^2-4\times \:1\times \:2}}{2\times \:1}$

$\sf \sqrt{\left(-1\right)^2-4\times \:1\times \:2}$

$\sf =\sqrt{-7}$

_________________

$\sf x_1,_2\cfrac{-\left(-1\right)\pm \sqrt{-7}}{2\times \:1}$

$\sf -(-1)=1$

$2\times 1=2$

$\sf x_1,_2=\cfrac{1\pm \sqrt{-7} }{2}$
