3x - 2y = -18 use the table of vaules to graph the line
docker41 [41]

Answer:

Given the equation of line :  3x -2y = -18

Table values:

x                  y

0                  9

2                  12

4                   15

6                   18

-6                  0

Now, plot these points (0,9), (2, 12), (4, 15) , (6, 18) and (-6, 0) on the co-ordinate planer, to graph the the line.

You can see the graph of the given equation as shown below.

On his way to a local Hunting and Gathering Convention, Caveperson Stony Grok picks up a rock, drops it into a lake and watches
olganol [36]

Answer:

I guess that "Ura nok seblu" means that all rocks sink in water.

Step-by-step explanation:

A conjecture is an idea, opinion, theory or hypothesis, that is based on partial or incomplete information or evidence. Conjectures are generally speculations since there is not enough proof or evidence to support them.  

Even though Stony's theory didn't have a lot of evidence to support it, he was almost right. Most rocks sink in water, I guess that the only rock that doesn't is pumice. I might be wrong, but I don't know of any other rock that floats.

Denise is constructing a square. she has already used her straightedge and compass to construct the circle, lines, and arcs show
Tpy6a [65]
What should denise do for her next step?

Answer: Out of all the options presented above the one that best represents the next step that denise should take after already using her straightedge and compass to construct the circle, lines, and arcs is to use the straightedge to draw line ac, line ad, line bc, and line bd. use the compass and straightedge to construct the bisector of ∠cpb∠cpb. Please see the attachment as reference to how it should look like once it is completed.

I hope it helps, Regards.

Find the zero of the following function f. Do not use a calculator. f (x )equals 1.5 x plus 3 (x minus 3 )plus 5.5 (x plus 7 )
Solnce55 [7]

Answer:

(-2.95,0)

x = -2.95 is the zero of the function.                                                      

Step-by-step explanation:

We are given the function:

f(x) = 1.5x + 3(x-3) + 5.5(x+7)

We have to find the zero of the function.

Zero of function:

  • It is the value where the function have a value zero.
  • (a,0)  such that f(a) = 0

We can find zero of the function in the following manner:

f(x) = 1.5x + 3(x-3) + 5.5(x+7) = 0\\1.5x + 3x -9 + 5.5x + 38.5 = 0\\(1.5x + 3x + 5.5x) + (38.5-9) = 0\\10x + 29.5 = 0\\10x = -29.5\\x = -2.95            

Thus, x = -2.95 is the zero of the function.

Which student solves and explains the equation correctly? Will choose brainliest.
-Dominant- [34]

Answer:

Jerry  is correct

Step-by-step explanation:

8^{x} = 512

this equation is asking 8 to what power is 512

Emma said the solution is x=3. Her explanation is 8 x 3 which would equal 24. This is not the correct answer.

Jerry's solution  is x = 3. His explanation is 8 x 8 x 8 which would equal 512. This is the correct answer.

Mel's solution is x = 8. Her explanation is 8 x 3 which equals 24. This is not the correct answer.

Victoria's solution is x = 8. Her explanation is 8 x 8 x 8 which would equal 512. However, her explanation is correct, her solution is not. 8^{8} = 16777216. That is what her solution is saying.
