Answer:
y = 5
The value of y is 5.
Step-by-step explanation:
RS + ST = RT
4y + 2 + 2y + 7 = 10y - 11
4y + 2y + 2 + 7 = 10y - 11
6y + 9 = 10y - 11
-9 -9
-------------------------
6y = 10y - 20
-10y -10y
-------------------------
-4y = -20
/-4 /-4
-------------------------
y = 5
=[(sinx/cosx)/(1+1/cosx)] + [(1+1/cosx)/(sinx/cosx)]
=[(sinx/cosx)/(cosx+1/cosx)]+[(cosx+1/cosx)/(sinx/cosx)]
= [sinx/(cosx+1)] + [(cosx+1)/sinx]
= [sin^2x+(cosx+1)^2] / [sinx (cosx+1)]
= [2+2cosx] / [sinx(cosx+1)]
=[2(cosx+1)] / [sinx (cosx+1)]
= 2/sinx
= 2 cscx

Answer:
w(-4.2) = 3(-4.2) -1 = -12.6 - 1 = -13.6
Step-by-step explanation:
The w(-4.2) is your t so you substitute it in your expression which means you get 3(-4.2) -1 and that gives you -13.6.
20:1,2,4,5,10,20

and the greater common factor is 4
Answer:
y = -6
Step-by-step explanation:
-4-2y=-12
4+8y=-24
We can eliminate 4.
4+8y-4-2y = -12-24
Simplify.
6y = -36
Find y.
y = -36 ÷ 6
Simplify.
y = -6
