What value of x is in the solution set of 3(x – 4) ≥ 5x + 2? <br><br> –10<br> –5<br> 5<br> 10
emmasim [6.3K]

<u>Answer:</u>

The value of x is in the solution set of 3(x – 4) ≥ 5x + 2 is -10

<u>Solution:</u>

Need to determine which value of x from given option is solution set of 3(x – 4) ≥ 5x + 2

Lets first solve 3(x – 4) ≥ 5x + 2

3(x – 4) ≥ 5x + 2

=> 3x – 12 ≥ 5x + 2

=> 3x – 5x ≥ 12 + 2

=> -2x ≥ 14

=> -x ≥ 7

=> x ≤ -7

All the values of x which are less than or equal to -7 is solution set of 3(x – 4) ≥ 5x + 2. From given option there is only one value that is -10 which is less than -7  

Hence from given option -10 is solution set of 3(x – 4) ≥ 5x + 2.

Which equation in rectangular form describes the parametric equations x=2-3 cos t and y=1+4 sin t?​
liraira [26]

Answer:

The parametric equations represents an ellipse by the rectangular equation \frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1.

Step-by-step explanation:

We proceed to use the following trigonometric identity to derive an expression in rectangular form:

\cos^{2} t + \sin^{2} t = 1 (1)

Where:

\cos t = \frac{2-x}{3} and \sin t = \frac{y-1}{4}

Then, we expand the expression as follows:

\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1 (2)

The parametric equations represents an ellipse by the rectangular equation \frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1.
