Slope = -10
<span>pass through (2,-5)
y = mx + b
so
b = y - mx
b = -6 - (-10) (2)
b = -6 + 20
b = 14

Answer:
55.96 miles
Step-by-step explanation:
Distance = Speed X time
Car first moved east for 1 hr , distance = 40 x 1 = 40 miles
Car then moved north-east for 30 min, distance = 40 x 0.5 = 20 miles
From trigonometry,
sin 45 =  ; y = 20 sin 45 ; y= 14.14 miles
 ; y = 20 sin 45 ; y= 14.14 miles
cos 45 =  ; x = 20 cos 45 ; x = 14.14 miles
 ; x = 20 cos 45 ; x = 14.14 miles
using Pythagoras theorem;
 =

Answer:
<u>x = -7.5 - 1.5(n−1) </u>
Step-by-step explanation:
 the explicit formula for the arithmetic sequence has the form 
x = a + d(n−1) 
a is the first term and d is the common difference
The given arithmetic sequence is 
-7.5,-9,-10.5,-12
The first term is -7.5
d = common difference = -9 - (-7.5) = -1.5
∴ x = -7.5 - 1.5(n−1)
