Answer:
- 3108
Step-by-step explanation:
The sum to n terms of an arithmetic series is
= [ 2 + (n - 1)d ]
Substitute the given values into the formula
= [ (2 × - 26) + (23 × - 9) ]
= 12 ( - 52 - 207 )
= 12 × - 259 = - 3108
90° clockwise rotation or 270° anticlockwise rotation
(x,y)=(y,-x)
<em>E(-6,-4)=E'(-4,6)</em>
<em>F(-4,-4)=F'(-4,4)</em>
<em>G(-2,-6)=G'(-6,2)</em>
<em>H(-7,-7)=H'(-7,7)</em>
Therefore, E prime is (-4,6), F prime is (-4,4), G prime is (-6,2) and H prime is (-7,7).
10.4 miles
Write an equation for the total cost paid as a function of the # of miles driven:
L(x) = $6.75 + ($3.20/mile)x
and set this equal to $40.03 to determine the # of miles Lupita rode:
L(x) = $6.75 + ($3.20/mile)x = $40.03
Isolate the x term by subtracting $6.75 from both sides:
($3.20/mile)x = $40.03 - $6.75 = $33.28
Finally, divide both sides by ($3.20/mile):
x = $33.28 / ($3.20/mile)
= 10.4 miles
Lupita rode 10.4 miles in the taxi.
