Answer:
x=-3.5, x=13.5
Step-by-step explanation:
-10x-47=-x^2+1
<u>switch sides</u>
-x^2+1=-10x-47
<u>add 47 to both sides</u>
-x^2+1+47=-10x-47+47
<u>simplify</u>
x^2+48=-10x
<u>add 10x to both sides</u>
-x^2+48+10x=-10x+10x
<u>simplify</u>
-x^2+10x+48=0
<u>solve with the quadratic formula</u>
a=-1, b=10, c=48:
x=-10±√10²-4(-1)48/ 2(-1)
(you can plug this into a calculator or use PEMDAS to solve)
(solve it twice: use - once, and + the second time)
<u>answer:</u>
x=-3.5, x=13.5

Step-by-step explanation:
(-1,4) is the only coordinate provided that is being covered by both shaded parts.
Answer:
tanB
Step-by-step explanation:
In the picture attached, the question is shown.
By definition:
tan(β) = opposite/adjacent
From the picture, for angle B the opposite side measure 8 units and the adjacent side measures 15 units. Replacing into the equation:
tan(B) = 8/15
From 8:15 to 12:15 is 4 hours so u will make $64 then from 13:00 to 17:30 is 5 hours and 30 minutes so $64 plus $88 is $152 that means the pay will be $152.
