Answer:

it is the second option. answer is x\leq-8/3 or x>4

Step-by-step explanation:

we have the inequality 3x+8/x-4=0

we first multiply both sides by 4 the 4 cancels out on the left-hand side and  4*0 is 0 so we now have 3x+8=0 then we subtract both sides by 8 and get 3x=-8 then we divide both sides by 3 and get x=-8/3  

x\leq-8/3 works in the original inequality

-8/3\leqx\leq4 does not work

x>4 does work

How much water do you add...
Alecsey [184]

Answer: 36.67 grams of water is added.

Step-by-step explanation:

Let the amount of water is added be 'x'.

Amount of sugar = 5 g

We need to make 12% of sugar syrup.

x grams of water is added to 5 g of sugar, to 12% of sugar syrup.

so, it becomes,

\frac{5}{5+x}=\frac{12}{100}\\\\100\times 5=12(5+x)\\\\500=60+12x\\\\500-60=12x\\\\440=12x\\\\\frac{440}{12}=x\\\\36.67\ g=x

Hence, 36.67 grams of water is added.

-9x+7y=28 find the y intercept
natulia [17]

In slope-intercept form, we have these values (y = mx + b):

m = slope

b = y-intercept

Change the equation from standard form to slope-intercept form.

-9x + 7y = 28

-9x + 9x + 7y = 28 + 9x

7y = 28 + 9x

7y/7 = 28/7 + 9x/7

y = 4 + 9/7x

y = 9/7x + 4

Therefore, the y-intercept is 4.

Best of Luck!

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a​ single-strand electric
allochka39001 [22]
I'm fairly certain that using that wire you can have the same area no matter what dimensions there are, but if you do the square root, or \sqrt{} of 19,001,900 then you get 4359.11688. So your dimensions are 4359.11688 x 4359.11688. To get area, do length x width to get <span>1.9*1 0^{7}.

Hope this helped! If it did, please give me a good rating and mark me brainiest.<span /></span>
