Answer:

x=16

Step-by-step explanation:

Since RQTS is a parallelogram

$\angle Q +\angle T=180^{o}$

$3x+5+9x-17=180^o$

$12x-12=180^o$

$12x-12+12=180+12$

$12x=192$

$\cfrac{12x}{12}=\cfrac{192}{12}$

$x=16$

Hope it helps!

Answer:

$92.86

Step-by-step explanation:

Since it's AT LEAST 1800, the inequality sign would be ≥ 1800

Equation:

500 + 14x ≥ 1800

14x ≥ 1800 - 500

14x ≥ 1300

x ≥ 92.86

In a function, y varies inversely with x. The constant of variation is 4. Which table could represent the function?

Colt1911 [192]

I don't see a table but I can give you the means to answer it yourself. The inverse function is represented by this: $y= \frac{k}{x}$ where k is your constant. You are given a k value of 4. If you solve this for k then you will get xy=4. In your tables, multiply your x value by your y value within your coordinate points and if you get a product of 4 each time you multiply x by y, then that table is your answer.

I will either mark the best or the first brainliest.

Y is the output and x is the input. The given statement is output is 11 more than the output (x) so the function rule is y=x+11
