Answer:

No solutions

Step-by-step explanation:

3x+4y=-4

15x+20y=-22

——————————

-5(3x+4y)=-5(-4) multiply 1st equation by -5 so you can eliminate the variables

-15x-20y=20. Modified 1st equation

15x+20y=-22. 2nd equation

0+0=-2. Added two equations together

since 0 does not equal -2, there is no solution.

Please solve this problem

asambeis [7]

Answer:

(4) 0

Step-by-step explanation:

Given:

cos²27°×cos²34°×...×cos²167 = ?

Looking at the angles measures, they form series of:

27, 34, 41, ..., 167

This is AP with the first term of 27 and common difference of 7

We can see one of the terms of this AP is 90

27+9*7 = 27 + 63 = 90

Since cos 90° = 0 ⇒ cos²90° = 0 and therefore given series equals to zero as one of the terms of multiplication is zero.

So correct answer choice is Option 4) 0

Can anyone do this with steps ..

Harrizon [31]

$\\ \sf\longmapsto \displaystyle{\lim_{x\to 0}}\dfrac{sinx-sin3x}{sins3x-sinx}$

$\boxed{\sf \displaystyle\lim_{x\to 0}\dfrac{f(x)}{g(x)}=\dfrac{\lim_{x\to 0}f(x)}{\lim_{x\to 0}g(x)}}$

Now

$\\ \sf\longmapsto \displaystyle{\dfrac{\lim_{x\to 0}sinx-\lim_{x\to 0}sin3x}{\lim_{x\to 0}sin3x-\lim_{x\to 0}sinx}}$

$\boxed{\sf \displaystyle{\lim_{x\to 0}}f(x)=f(a)}$

$\\ \sf\longmapsto \dfrac{sin0-sin3(0)}{sin3(0)-sin0}$

$\\ \sf\longmapsto \dfrac{0-0}{0-0}$

$\\ \sf\longmapsto \dfrac{0}{0}$

$\\ \sf\longmapsto 0$
