Denote points:

  • G - gas station;
  • M - motel;
  • S - sister's home.

These three points lie on the same line in order M, G and S. The distance MS=341 mi and MS=GM+GS.

It takes Doug 3 hours to go to a motel from gas station (GM) and it takes 2.5 hours Ashley to go to a sister's home from gas station (GS). The total time is 3+2.5=5.5 hours.

Then using the formula d=rt, you can conclude that

341=5.5·r,

r=341:5.5,

r=62 mi/h.

Answer: 62 mi/h.

Identify the domain and range of the function f(x) = 2x2 − 6x − 9.
mash [69]
Range is the y values or ouputs
domain is inputs or x vvalues

we can use any x value
but at a certain y value, w can't go below that
find thatminimum
find the vertex
for
ax^2+bx+c
the x value of the vertex is
-b/2a
plug that in to the equaiton to get the y value

-b/2a=-(-6)/(2*2)=6/4=3/2

plug that in
2(3/2)^2-6(3/2)-9
2(9/4)-9-9
9/2-18
4.5-18
-13.5

domain=all real numbers
range=from -13.5 to positive infinity
