\cos x-\sin^2x-1\\/use\ \sin^2x+\cos^2x=1\to\sin^2x=1-\cos^2x/\\\\=\cos x-(1-\cos^2x)-1=\cos x-1+\cos^2x-1\\=\cos x-1+\cos^2x-1^2\\/use\ a^2-b^2=(a-b)(a+b)/\\\\=\cos x-1+(\cos x-1)(\cos x+1)\\=1(\cos x-1)+(\cos x+1)(\cos x-1)\\\\=\boxed{(\cos x-1)(1+\cos x+1)=(\cos x-1)(\cos x+2)}

Someone please help me I’ll give out brainliest please dont answer if you don’t know
Katena32 [7]

Answer:

x≥−3

Step-by-step explanation:

Let's solve your inequality step-by-step.

2x+3/ −3 ≤1

Step 1: Simplify both sides of the inequality.

−2/ 3 x−1≤1

Step 2: Add 1 to both sides.

−2/ 3 x−1+1≤1+1

−2/ 3 x≤2

Step 3: Multiply both sides by 3/(-2).

( 3/ −2 )*( −2/ 3 x)≤( 3/ −2 )*(2)

x≥−3

Answer:

x≥−3

Given that (-8,-5) is on the graph of f(x), find the corresponding point for the function f(x-2)
Volgvan
This one works the same way the last one did.

If -8 is x-2, then x = -6. The corresponding point is (-6, -5).
