Answer:
11
Step-by-step explanation:
Let v = number of video's she bought
Let c = number of CD's she bought
v+c=16
1495v+1688c=9355
Multiply both sides of (1) by 1495
and subtract (1) from (2)
-1495v-1495c=-8970
193c=386
c=2h

$10,890
Step-by-step explanation:
5.5% × 198000 = 10890
Answer:
D. (y+1)=5(x+2)
Step-by-step explanation:
Point-slope form follows: y - y1 = m(x - x1)
Since both x and y are negative for (-2,-1), it becomes a positive because two -'s become a +.
m(slope)=5
y-(-1)=5(x-(-2))
y+5=5(x+2)
Distance = SQRT(x^2+y^2)
x = 4 - (-2) = 6
y = 3 - 2 = 1
distance = SQRT(6^2 + 1^2) = SQRT(36+1) = SQRT(37) = 6.1
