Use the quadratic formula to solve x^2-4x+3. Show your work. Then describe the solution

mars1129 [50]

Quadratic formula is x=(-b+-sqrt(b^2-4ac))/(2a)

a= 1, b=-4, and c=3

Therefore, x=(-(-4)+-sqrt((-4)^2-4(1)(3))/(2(1))

Solve for both the plus and minus equations; the answers will be the roots to the quadratic equation.

jonny [76]

Answer:

Yes Maggie has enough money to purchase the dress and hair accessory.

Step-by-step explanation:

Dress = $35.75

Hair accessory = $2.80

Total amount of money = $40

Does her have enough money?

Total Money in pocket - (Dress cost + hair accessory)

$40.00 - ($35.75 + 2.80)

$40.00 - ($36.00 + $3.00) Round to the nearest dollar

$40.00 - $39.00 = $1.00

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-1, -13)

Point (-1, 21)

Step 2: Find distance d

Substitute in points [DF]: $\displaystyle d = \sqrt{(-1+1)^2+(21+13)^2}$
(Parenthesis) Add: $\displaystyle d = \sqrt{(0)^2+(34)^2}$
[√Radical] Simplify: $\displaystyle d = \sqrt{(34)^2}$
[√Radical] Evaluate: $\displaystyle d = 34$
