Answer:
$219.75
Step-by-step explanation:
Just plug in the values
x = final cost
31.95(5) + 0.10(600) = x
159.75 + 60 = x
219.75 = x
Um. Could you finish the question
Answer:
double becuase i can doubleand then subtract by one
Step-by-step explanation:
First find the slope of the line DM using the slope formula: .
Use the points D(0, 2) and M(-3, -5). Substitute in -5 for y2, 2 for y1, -3 for x2, and 0 for x1.
, subtract the coordinate points.
= ; the slope of the line DM is 7/3.
Perpendicular lines have opposite reciprocal slopes, meaning you switch the sign (say for example a negative becomes a positive, a positive becomes a negative) and you flip the fraction over (for example 1/2 becomes 2/1 and 2/1 becomes 1/2).
The opposite reciprocal of 7/3 is -3/7, so the line perpendicular to the line DM has a slope of -3/7.
His new position is 3.75 meters 12.25 - 8.5 = 3.75.
Her new position is 20 ft 9 1/2 + 10 1/2 = 20.
