Answer:
a. Emily should begin her turn as the third driver at point (1, -0.5).
b. Emily's turn to drive end at point (-2.5, -3.75).
Step-by-step explanation:
Let assume that the group of girls travels from their hometown to San Antonio in a straight line. We know that each location is, respectively:
Hometown

San Antonio

Then, we can determine the end of each girl's turn to drive by the following vectorial expression based on the vectorial equation of the line:

a. <em>If the girls take turns driving and each girl drives the same distance, at what point should they stop from Emily to begin her turn as the third driver? </em>
Emily's beginning point is the Andra's stop point, that is,
.
Emily should begin her turn as the third driver at point (1, -0.5).
b. <em>At what point does Emily's turn to drive end?</em>
Emily's turn to drive end at point (-2.5, -3.75).
Mhm 86(7)+88=839 that’s ur answer
3/8 x 2/6 = 6/48 which simplified is 1/8
79.30 ---- 100%
The while store is discounted by 12% So subract 12 from 100
100-12 = 98
We have to figure out what 88% is
79.30 ---- 100%
X ------------ 88%
Cross Multiply
79.3× 88 = 100x
6978.4 = 100X
69.784 is without taxes
69.784 = 100% {100% because it is the total price.}
69.784 = 100%
X --------- 6.25%
Cross Multiply
69.784 × 6.25 = 100X
436.15 = 100 X
X = 4.3615
69.784 + 4.3615
74.15 is the answer
