A parabola intersects the x-axis at x=3, equals, 3 and x=9.

Answers

Answer: x is 6

Step-by-step explanation:

where a and b are x intercepts given to us.

So rewriting in factored form:

y = (x-3)(x-9)

so now you have to simplify it using the formula y=ax^(2)+bx-c

y= x^(2)- 12x+27

so with this formula x=(-b)/(2a) we can find the x coordinate

x=(-(-12))/(2(1))

and the answer would be 6

Madi bought 11 ft of ribbon for $1.32 per yard. How much did she pay for the ribbon?

Answers


First you need to figure out how many yards of ribbon you are buying. To do that divide 11 by 3. That equals 3 2/3 yards. You divided it by 3 because there are 3 feet in 1 yard.

next you need to change 3 2/3 yards into an improper fraction. Multiply the  whole number 3 by the denominator that ='s 9 and it to the numerator that ='s 11 so now you have the improper fraction 11/3 that represents the number of yards of ribbon you are buying.   Then multiply $1.32 * 11/3 = $14.52/3  reduced = $4.84

Paid $4.84 for the ribbon 
There are three feet of ribbon in a yard. So 11 feet is 3.66 yards. Then multiply the cost of a yard by the number of yards (1.32 times 3.66) and you get the answer: 4.83 dollars
