The eccentricity of the conic section below is <u>1, </u>since the conic section given is a parabola.
The eccentricity of a parabola is <u>1</u>.
Hope that made sense !!

Formula for markup
sales price = original price × ( 1 + rate )
So in this case it would be...
sp = $32 × ( 1 + .80 )
$32 × ( 1.80 )
sp = $57.60
formula for discount ( if you need it )
sales price = original price × ( 1 - rate )
Just remember that the rate is the percentage ( to convert to a percentage to a decimal just move the decimal two places to the left )
2( -7) + (-11)(-4)
= -14 + 44 = 30
Second one 7-(-3) = 10
Answer:
-128 it’s on the table

Answer:
We can start by rewriting the initial equation x +10y=260 in order to express how y depends on x.
This is a linear function ( it's a straight line). Linear functions have two intercepts, y and x.
To find x-intercept (also called zero of a function) we set y=0 and we solve for x.
This means that at x=260 our function has a value of 0. y(x) represents a distance from the school. This means that when y(x) is 0 our athlete reached school (finished the race), so this also answers your second question. The time it takes an athlete to finish the race is 260 minutes.
The y-intercept a value of our function at x=0. This gives us a distance of our athlete from the school at the start of the race. We find this by plugin x=0 in our equation. We get that y=26 when x=0. This makes perfect sense. Our athlete is 26 miles away from high school at the start of the race.
