Solve the simultaneous equations

Answer:

Step-by-step explanation:

4x + 3y = 24

4x - y = 8

4x + 3y = 24

-4x + y = -8

4y = 16

y = 4

4x - 4 = 8

4x = 12

x = 3

Simplify for a lot of points<br> (1-sin^2x)(1-tan^2x)

notka56 [123]

1/sin^2x-1/tan^2x=
1/sin^2x-1/ (sin^2x/cos^2x)<<sin tan= sin/cos>>
= 1/sin^2x- cos^2x / sin^2x
= (1- cos^2x) / sin^2x <<combining into a single fraction>>
sin^2 x / sin^2x <<since 1- cos^2 x sin^2 x

=1
this simplifies to 1.

Follow the directions to solve the system of equations by elimination.

Ber [7]

8x + 7y = 39
4x - 14y = -68

(multiply each term in second equation by -2)

8x + 7y = 39
-8x + 28y = 136

(add both equations)

35y = 175

(divide both sides by 35)

y = 5

(substitute value of y in one of the equations)

8x + 7(5) = 39
8x + 35 = 39
8x = 4
x = 1/2
(x, y) = (1/2, 5)

Anybody know how to do this? I need Help Now!!!!!

Hi there!

The answer is
$x \leqslant - 5$

We have the following inequality.
$- 6x \geqslant 30$

We can divide both sides by -6, but because we divide by a negative number, we must flip the sign.

$x \leqslant 30 \div - 6$
$x \leqslant - 5$
