0: Shelby set a goal to run 3.1 miles. Today she ran 2.6 miles. What percent of her goal did she run?

step-by-step explanation:

classify each pair of angles as alternate interior, same-side interior, or corresponding angles.

4n=2m

ratio of m to n: 2/4 = 1/2

answer

a. 1/2

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
