So percents are just written as 20% = 0.2 so keep that in mind
139 divided by 0.2 is 95 , which would be the price after the discount :)
hope this helps!

The answer to the question above is x=-4.5
Answer:
B. y=3(x-1)2 + 3
Step-by-step explanation:
Given that
vertex of the parabola is at the point (1,3)
let's verify, if the option B is the correct equation of the parabola.

comparing to standard equationof parabola (standard quadratic equation), we get

to find the vertex we use formula for x- coordinate as 

to find y put x=1 in the Eq1, we get

vertex =(x,y) = (1, 3)
thus vertex of the parabola from the equation y=3(x-1)2 + 3 is (1,3), thus verified

Answer:
no
Step-by-step explanation:
We can use the Pythagorean theorem to check
a^2 +b^2 = c^2
11^2+13^2 = 17^2
121+169 =289
410 does not equal 289
This is not a right triangle
