x+y=165
15x+5y=1775

using a graph tool
see the attached figure

the solution is
x=95
y=70

the answer is

Which expression is equivalent to (sin x + 1)(sin x − 1)? A. cos2x B. -cos2x C. cos2x + 1 D. cos2x − 1 E. -cos2x + 1

Semenov [28]

ANSWER

$- \cos^{2} x$

EXPLANATION

The given expression is

(sin x + 1)(sin x − 1)

Note that:

$(x + 1)(x - 1) = {x}^{2} - 1$

This implies that,

$( \sin \: x + 1)( \sin \: x - 1) = \sin^{2} x - 1$

We can factor -1 on the right hand side to get,

$( \sin \: x + 1)( \sin \: x - 1) = - (1 - \sin^{2} x )$

Note that from the Pythagorean Identity

$1 - \sin^{2} x = \cos^{2} x$

We apply this identity to obtain:

$( \sin \: x + 1)( \sin \: x - 1) = - \cos^{2} x$

The correct choice is B

If five slices of pizza cost $5.50 how many would 2 slices cost, ten slices, half a slice?

Lana71 [14]

To find the answer, you divide 5.50 by 5 to get the price of one slice of pizza. We get that one slice is $1.10. 2 slices would be $2.20. 10 slices would be $11. Half a slice would be $0.55. Hope this helps!
