Answer:
-5
Step-by-step explanation:
-3y = 10 + 5
-3y = 15
y = - 5
Csc a - sin a = cos a cot a
1/sin a - sin a = cos a (cos a / sin a)
(1 - sin^2 a)/sin a = cos^2 a/sin a
cos^2 a/sin a = cos^2 a/sin a
Therefore, the given equation is an identity.
Answer:
I hope it helps u
Step-by-step explanation:
Let's solve your system by elimination.
15j+12k=18;5j+4k=6
Multiply the second equation by -3, then add the equations together.
(15j+12k=18)
−3(5j+4k=6)
Becomes:
15j+12k=18
−15j−12k=−18
Add these equations to eliminate j:
0=0
Answer:
Infinitely many solutions

Answer:
Step-by-step
The sum must be greater than 1 because
1/2 + 1/2= 2/2 or 1
ex
3/4 + 8/4= 11/4
9/16+15/16=24/16
8/8+9/8=17/8
Answer:
Step-by-step explanation:
In order to solve for b, we must isolate the variable. We can start by subtracting 5 from both sides.
Simplify.
Add b to both sides.
Simplify.
Multiply everything by 3 to remove the fractions.
Simplify.
2b + 3b = 45
Simplify.
5b = 45
Divide 5 from both sides.
5b ÷ 5 = 45 ÷ 5
Simplify.
b = 9
