Answer:
k-l= 7 -3
6 0
Step-by-step explanation:
k-l=13 7 - 6 10
25 18 19 18
= 13-6 7-10
25-19 18-18
= 7 -3
6 0
7) Vertex = V(2,3)
9) Vertex = V(2,1)
17) The smaller the absolute value of the coefficient of x², the larger is the opening of the parabola. (to compare, just take the absolute value of a)
Coefficients are (5), (-3) and (1):
Widest: f(x) =x², followed by f(x) = -3x² and the narrowest is f(x) =5x².
A slice of pizza has concentric angle of 360/8=45.
There are 6 such angles so 45*6=270.
Hope this helps.
