Robin is playing a trip to Corpus Christi. she knows that it’s 400 miles away but she doesn’t want to speed so she will go 65/ miles per hour the whole way. How long will it take her to get there ?

80/13 hours

Step-by-step explanation:

distance= 400 mile

speed= 65miles/hour

Time 400/65

80/13 hours

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
