Autumn got a 20% reward of the $900 she found.
Tan(x)= sin(x)/cos(x), therefore, substitute sin(x)/cos(x) in the expression:
=(cos(x)(sin(x)/cos(x))-1)/cos^2(x)
simplify the 2 cos(x):
=(sin(x)-1)/cos^2(x)
Sin^2(x)+ cos^2(x)=1, sin^2(x)-1=- cos^2(x), substitute in the expression:
= -cos^2(x)/cos^2(x)= -1
Answer:
x = (-12/7 , 0)
y= (0,4)
Step-by-step explanation:
Plug y=0 into the equation and solve the resulting equation 7x=−12 for x
7x = -12
/7 /7
x = -12/7 and y =0
Plug x=0 into the equation and solve the resulting equation −3y=−12 for y
-3y = -12
/-3 -3
Y = 4 and X = 0
A ratio indicates how many times one number contains another examples 4:3 2:3
