Answer:

x < = -6

Explanation:

The arrow points -6 and then to the left side, where lies negative numbers, all along. The dot is filled and points that x is also equal to -6 and less than that of -6. Therefore the inequality is:

x < = -6

${Interval\:Notation:}&\:\left(-\infty \:,\:-6\right)\end{bmatrix}$

Starting point of arrow is -6.
The arrow is travelling to wards left.
I.e the arrow is decreasing and x is decreasing.

Hence the solution is

$\\ \tt\hookrightarrow x\in (-\infty,-6]$

x<=-6

Determine whether quantities vary directly or inversely and find the constant of variation. It takes four identical water pumps

NNADVOKAT [17]

Let the number of water pumps be n and the time taken to fill the pool is t.

Now, we can see that higher the number of water pumps, lesser the time to fill the pool.

It means quantities vary indirectly.

Thus, $n=\frac{k}{t} , \text{ where k is the constant of variation}$

Now, we have been given that It takes four identical water pumps 6 hours to fill a pool.

Thus, we have

$4=\frac{k}{6} \\
\\
k=24$

Hence, constant of variation is 24.

Now, we have to find the time that three pumps will take to fill the same pool.

$3=\frac{24}{t} \\
\\
3y=24\\
\\
y=\frac{24}{3} \\
\\
y=8$

Hence, it will take 8 hours to fill the pool by three identical pumps.

Emily got a new job that guarantees her a 8% raise every year. If she started out making $25,000, how long will it be before she

juin [17]

Answer: 12 1/2 years

Step-by-step explanation:

If the salary doubling in currency, it would need a 100% raise. Simply divide 100% by 8% to get the number of years needed.

100 / 8 = 12.5 or 12 1/2

8% of 25,000 = 2,000

25,000 / 2,000 = 12.5 or 12 1/2

What equation would have the points containing (8,3) and (13,5)

Novay_Z [31]

The answer would be y= 2/5x because 5-3 =2 so you put that on top and 13-8 =5 and you put that on bottom

x+4y=17 and -x-6y=-23 what's the x and y I really badly need this I need this so I can play at my basketball game tommorw and I

loris [4]

Answer:

x = 5
y = 3

Solution:

=> x + 4y = 17

-x - 6y = -23

=> -2y = -6
=> y = 3

Now, let's substitute the value of y into the first equation.

x + 4y = 17
=> x + 4(3) = 17
=> x + 12 = 17
=> x = 5

Let's check our answer to make sure it is correct.

Check:

-x - 6y = -23
=> -(5) - 6(3) = -23
=> -5 - 18 = -23
=> -23 = -23

Hence, this is proven correct.

Hoped this helped.
