If it's possible to tell, decide if a and b are positive or negative: a-3>b-3 and b>4
Svetllana [295]

Answer:

a and b are positive

Step-by-step explanation:

We are given that

a-3>b-3

b>4

We have to find that a and b are positive or negative.

We have

b>4

It means b is positive and greater than 4.

a-3>b-3

Adding 3 on both sides

a-3+3>b-3+3

a>b>4

\implies a>4

Hence, a is positive and greater than 4.

Therefore, a and b are positive

Lady bird [3.3K]
2cos^2 x = 1 + cos 2x
cos^2 x = 1/2(1 + cos 2x)
f(x) = 6cos^2 x - 4 sin 2x = 6(1/2(1 + cos 2x) - 4 sin 2x = 3 + 3cos 2x - 4sin 2x

-3(3+x)+4(x-6)=-4 Please help me with this question
dsp73

Answer:

\boxed{ \bold{ \huge{ \sf{x = 29}}}}

Step-by-step explanation:

\sf{ - 3(3 + x) + 4(x - 6) =  - 4 }

Distribute -3 through the parentheses

Similarly, Distribute 4 through the parentheses

⇒\sf{ - 9 - 3x + 4x - 24 =  - 4}

Collect like terms

⇒\sf{x - 9 - 24 =  - 4}

Calculate

⇒\sf{x - 33 =  - 4}

Move 33 to right hand side and change it's sign

⇒\sf{x =  -  4 + 33}

Calculate

⇒\sf{x = 29}

Hope I helped!

Best regards!!
