Answer:
u = -2

Explanation:
Slope of the line can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)

We are given :
slope = 1/8
point (u,-9) represent (x1,y1)
point (6,-8) represent (x2,y2)

Substitute with the givens in the above equation and solve for u as follows:
slope = (y2-y1) / (x2-x1)
1/8 = (-8--9) / (6-u)
1/8 = (1) / (6-u)
1* (6-u) = 1*8
6-u = 8
u = 6-8
u = -2

Hope this helps :)

Which number line represents the solution set for the inequality 3(8 – 4x) < 6(x – 5)?

diamong [38]

Answer:

A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right.

Step-by-step explanation:

We can start by dividing the inequality by 3 to get ...

8 -4x < 2(x -5)

And we can divide by 2 to simplify further to ...

4 -2x < x -5

Now, we can add 2x+5, which gives ...

9 < 3x

and then divide by 3 again:

3 < x

This is graphed on a number line as described above.

1 liter=.26 gallons so 20 liters= 20*.26= 5.2 gallons.

You need to use .75 ounces of soda ash per gallon so you must multiply .75 by 5.2.

.75*5.2 = 3.9 ounces

Graph y=-6(3)^x please do the table and the graph 20 POINTS!

Margarita [4]

Answer:

Explanation to the answer below... (Answers in the Explanation)

Step-by-step explanation:

We Know that our rule is y = $y = -6(3)^{x}$ , which means we can use this rule to find y from x. Since we don't know what X, is, we have to assume numbers like 1, to 7. And there is no space to write on the graph, I'll put a virtual copy of a graph.
