Answer:

C. 20% increase

Step-by-step explanation:

Process of Elimination: Remove options A and B from the answer choices since 60 > 50, so it can't be a decrease.

We're left with 20% and 25%

To represent 20%, do .2 x 50 which gives you 10.

If 10 + 50 = 60, then it was a 20% increase. Which 10 + 50 is 60.

So the answer is 20% increase.

Which equation represents a linear function that has a slope of 4/5<br> and a y-intercept of –6?

vredina [299]

Answer:

$\large\boxed{y=\dfrac{4}{5}x-6}$

Step-by-step explanation:

The slope-intercept form of equation of a linear function:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = 4/5 and the y-intercept b = -6. Substitute:

$y=\dfrac{4}{5}x-6$

Solve <br> 2(x+3)=5(x-4) in pair of equation

irina1246 [14]

Answer:

See below.

Step-by-step explanation:

2( x+3) = 5(x-4)

2x + 6 = 5x - 20

2x - 5x = -20 - 6

-3x = -26

x = 8 $\frac{2}{3}$

Sec^6x(secxtanx)-sec^4(secxtanx)=sec^5xtan^3x<br> Verify the trigonometric identity

mario62 [17]

I guess you mean

$\sec^6x(\sec x\tan x)-\sec^4x(\sec x\tan x)=\sec^5x\tan^3x$

On the left side, we have a common factor of $\sec^4x(\sec x\tan x)=\sec^5x\tan x$ , so that

$\sec^6x(\sec x\tan x)-\sec^4x(\sec x\tan x)=\sec^5x\tan x(\sec^2x-1)$

Recall that

$\sec^2x=1+\tan^2x$

from which it follows that

$\sec^5x\tan x(\sec^2x-1)=\sec^5x\tan x\tan^2x=\sec^5x\tan^3x$
