Answer:
A(-8, 6), D(-1, -16), E(17, -3)
Step-by-step explanation:
Any point with an x-value that matches any of {-8, -1, 5, 15, 17} will prove Mariela's claim incorrect. (A function cannot use an x-value more than once.)
Those points are ...
(-8, 6), (-1, -16), (17, -3)
$18.00 if you move the decimal one place to the left 10% tip would be $1.80,
multiply $1.80 x 2 = $3.60 which is 20% for the tip.
$18.00 + $3.60 = $21.60 divide by 4 people = $5.40 per person
Answer:
$901.88
Step-by-step explanation:
-20.10 + 1357.48 = 1337.38
1337.38 + 599 = 1936.38
1936.38 - (3*375) = 811.38
811.38 + (45.25*2) = 901.88
$901.88
Hope this helps!
Ok so first we need to work out the vertical line in the middle (ab) using Pythagoras
Square root(7.5^2+4.9^2) to get 8.958794562
Now we know the length of the line ab so we can work out x using trigonometry
Since line ab is opposite the angle and x is adjacent (or not the hypotenuse the slope) the tan rule is used which is tan(0)=o/a
So tan(55.8)=8.9587../a
*a. *a
/tan(55.8). /tan(55.8)
a=8.9587../tan(55.8)
a=6.088390497
a=6.09
x=6.09
Answer:
$17.12
Step-by-step explanation:
$21.40x.20= $4.28
$21.40-$4.28=$17.12
