Answer:
0.6-2.1=1.5
Step-by-step explanation:
0.6-2.1=-1.5
0.6-2.1= - I2.1-0.6I
2.1
-0.6
--------
1.5
Y=a (x-h) ^ + k
so your parabola has an equation of:
y=a(x+2)^ -3
-2=a(5+2) ^ -3
-2=a(-3)^-3
-2=9a-3
adding them to both sides
1=9a
divide both sides:
1=9a
Divide both sides by 9:
a=1/9
the vertex form is:
y=(1/9)(x+2)^-3
The expanded form is:
y=(1/9)x^ + (4/9)x - (23/9)
Anw: E. (1/9)
5x+6=8x-15
->x=7
m=180-5x-6-8x+15=98
