Equation A : x + z = 6
Equation B : 2x + 3z = 1

Possible step used in eliminating in  z-term.

Multiply equation A by -3.

-3(x +z) = -3(6)
-3x - 3z = -18

-3x - 3z = -18
 <u>2x + 3z =   1</u>
-x           = -17
<u>÷ -1           ÷ -1
</u>x             = 17

A line has the points (3,7) (4,9) (5,11) (6,13). If the slope is divided by 2, what is the new slope?
lorasvet [3.4K]

Answer:

The new slope is 1

Step-by-step explanation:

The slope of any two points can be found by:

slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Finding slope of (3,7) (4,9)

slope=\frac{9-7}{4-3}\\slope=\frac{2}{1}\\slope=2

Finding slope of (4,9) (5,11)

slope=\frac{11-9}{5-4}\\slope=\frac{2}{1}\\slope=2

So, the slope of the line is 2

Now if slope is divided by 2, new slope will be:

slope = \frac{2}{2}\\slope=1

So, The new slope is 1

What's the answer to this question 3x + 2y = -4 and how did you get it
Alex777 [14]

First you subtract 3x because you are trying to get x alone so subtract 3x on both side so you would get 2y=-3x-4 and then divide the whole thing by 2 so you would get y=-3-4/2 and then you simplify and get y=-7/2 so y=-7/2 is your answer.

A scientist measured the wavelength of an X-ray as 0.0000000065 meters.
ryzh [129]

Answer:

6.5 * 10 ^ -9

Step-by-step explanation:

0.0000000065

Scientific notation means a* 10 ^b

where a  is number between 1 and less than 10

Move the decimal  9 places to the right which means the power of 10 is negative since we moved the decimal to the right

6.5

The power of 10 is -9

6.5 * 10 ^ -9
