F(x)=x^2+6x-2, vertex: (-3, -11)
First, put -(6)/2(1) or -b/2a.
You then get -3 as the X value of the vertex.
Next, insert -3 back into the equation to get the Y value of the vertex.
(-3)^2+6(-3)-2 = -11
You then have -11 as the Y value of the vertex.
A.) alternate exterior angles
2.25h(60m/hr)(1/3)=45m
So Rick spends 45 minutes studying math per night.
Answer:
64 km/hr
Step-by-step explanation:
216 - 56 = 160 km on good road
216km / 48 km/hr = 4.5 hours total time
56 km / 28 km/hr = 2 hours on bad road
then 2.5 hours on good road ( for total 4.5 hrs)
160 km / 2.5 hr = 64 km/hr on the good road portion
Answer:
18
Step-by-step explanation:
x-5=(x+8)/2
x-5=x/2+4
add 5
x=x/2+9
subtract x/2
x/2=9
times 2
x=18
