How do i prove 2sec^2x-2sec^2xsin^2-sin^2x-cos^2x=1

kramer

$2\sec^2x-2\sec^2x\sin^2x-\sin^2x-\cos^2x=2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)$

Since $\sin^2x+\cos^2x=1$ , you have

$2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)=2\sec^2x\cos^2x-1$

and since $\sec x=\dfrac1{\cos x}$ , you end up with $2-1=1$ .

7th grade math help me pleaseeee

Eduardwww [97]

Answer:

4x + 5y = 20

Step-by-step explanation:

4x + 5y = 20

5y = -4x + 20 (Subtract 4x to isolate 5y. Put the 4x in front of the 20)

y = $-\frac{4}{5}x$ + 4 (Divide all by 5 to isolate y)

And then it's done and in slope-intercept form

$-1< -\frac{4}{5} < 0$ or $-\frac{4}{5}$ is greater than -1 but less than 0

I hope this helped :)
