Answer:

No solutions

Step-by-step explanation:

Solve for x the system of two inequalities:

$\left\{\begin{array}{l}-9x+5$

First, solve each inequality separately:

$-9x+5$

$13x+25$

Now, we get

$x>-\dfrac{4}{3}$

and

$x$

There are no common values for x, for which both inequalities hold, so the system of two inequalities has no solutions.

Given that x=3sinθ-2 and y=3cosθ+4.Show that (x+2)²+ (y-4)²=9

asambeis [7]

Answer:

First, plug-in x and y as 3sinθ-2 and 3cosθ+4 into the equation, respectively:

$((3\sin (\theta)-2)+2)^2 + ((3\cos (\theta)+4)-4)^2 = 9$

Then, +2 and -2 cancel out and +4 and -4 cancel out as well, leaving you with:

$(3\sin(\theta))^2+(3\cos(\theta))^2=9$

We can factor out 3^2 = 9 from both equations:

$9(\sin(\theta)^2+cos(\theta)^2) = 9$

We know from a trigonometric identity that $\sin(\theta)^2+cos(\theta)^2 = 1$ , meaning we can reduce the equation to:

$9(1) = 9$

$9=9$

And therefore, we have shown that (x+2)^2 + (y-4)^2 = 9, if x=3sinθ-2 and y=3cosθ+4.

Hope this helped you.

1- Find the value of the two numbers if their sum is 12 and their difference is 4. You must use an algebraic expression to solve

PilotLPTM [1.2K]

12-4=8 which means 12-8=4 which means now you have the difference of 4 and 8+4=12 which means now you have the sum of 12
