Answer: B' (5, -8)
Step-by-step explanation:
Rotating 180 around the origin rule:
(x,y)--> (-x-y)
B (-5,8) B' (5, -8)
Answer:
Step-by-step explanation:
x intercepts are -3,-1
f(x)=-(x²+x+3x+3)=-(x²+4x)-3=-(x²+4x+4-4)-3=-(x+2)²+4-3
or f(x)=-(x+2)²+1
vertex is (-2,1)
so it is an inverted parabola with vertex (-2,1) and x-intercepts (-3,0) and (-1,0)

Step-by-step explanation:
Considering they are congruent
if 7x-19=2x+11
how much is 6x-8
7x-19=2x+11
7x=2x+30
7x-2x=30
5x=30
X=6
6x-8=
(6*X)-8=
(6*6)-8=
36-8=
28
therefore
BC= 28
2x+11
(2*6)+11
12+11
23
23+28+24=75
therefore the perimeter is 75
