Answer:
Multiply each number by the little number next to it then add. It will be a huge number.
Step-by-step explanation: Above.
The value of the solution is 3π/2.
What is a trigonometric equation?
An equation involving one or more trigonometric ratios of unknown angles is called a trigonometric equation.
tan x/2 = -1
tanx/2 = tan(-π/4)
tanx=tanФ
⇒ The general equation of tanx=tanФ is
⇒ x=nπ+Ф
x/2=nπ+(-π/4)
at n=0
x/2=-π/4
x=-π/2
at n=1
x/2=π-π/4
x/2=3π/4
x=3π/2

Questions: Which value is a solution for the equation tan x/2 = -1?
A. 5pi/4
B. 7pi/4
C. 3pi/4
D. 3pi/2
you substitute 5y+41 for x and get 5y+41+3y=-15 then you simplify by doing 8y+41=-51 subtract 41 from each side and divide by 8 to get y alone. That's how you get 11.5 for your answer.
Answer:
-144ft below sea level
Step-by-step explanation:
It is a linear equation. Written as y=14x-270. So what you do is substitute x for 9,
y=14(9)-270
y=126-270
y=-144
$36 because 20% of 45 is 9 and 45 - 9 is 36!
