What is the vertex of the quadratic function below?
y = x2 + 12x - 7

(6,101)

Step-by-step explanation:

x value of vertex is given by b/2a in quadratic.

b=12 and a=1

that gives you a 6, then plug in x=6 in the quadratic equation and that gives you

y=101

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
