Answer any of the following please. All 4 answers would be nice:)
3. How can you tell when a one-variable equation has no solution?

4. What does it mean for an equation to have infinitely many solutions?

5. How can you tell when a one-variable equation has infinitely many
solutions?

6. Solving one of the equations results in x = 3. What can you
conclude about the number of solutions for this equation?

3. The coefficients are the numbers alongside the variables. The constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur.

4. The first is when we have what is called infinite solutions. This happens when all numbers are solutions.

5. When one side of an equation is identical to the other side, then there is an infinite number of solutions.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
