Which of the following equations have infinitely many solutions?

Mathematics

Answer:

Choice A

Step-by-step explanation:

In each case, each equation has an equation of a line in y = mx + b form equaling another equation of a line in y = mx + b form. If the two sides are equal, it is the same equation, there are infinitely many solutions. If the sides are different, then if the slopes are different, the lines intersect at one point, and there is exactly 1 solution. If the slopes are equal, the lines are parallel, and there is no solution.

(Choice A) -10x-10=-10x-10

In Choice A, both sides of the equation are equal, so there are infinitely many solutions.

(Choice B) 10x-10=-10x+10

(Choice C) 10x-10=-10x-10

(Choice D) -10x-10=-10x+10

In choices B through D, the two sides are not equal, so there is either 1 solution (B and C since they have different slopes) or no solution (D since the slopes are equal).

Which shows all the exact solutions of sin^2 x + 3cos x - 1 = 2?
Zarrin [17]

Answer:

x = 2k\pi is the solution of this equation.

Step-by-step explanation:

This question is related to trigonometric equations.

The given equation is,

sin^{2} x + 3cos x - 1 = 2

We have to find the solutions of this equation.

Put sin^{2}x  = 1 - cos^{2}x

1 - cos^{2}x + 3cosx - 1 = 2

cos^{2}x -3cosx+2 = 0

For this equation only cosx = 1 is possible solution.

Cosx = 1 happens when x is a multiple of 2\pi

So x = 2k\pi is the solution of this equation.
