Solve x − 2y = 3 for x.

wolverine [178]

Answer:

$x=2y+3$

Step-by-step explanation:

So we have the equation:

$x-2y=3$

And we want to solve for x. In other words, we want to isolate the x-variable.

So, add 2y to both sides of the equation.

$(x-2y)+2y=(3)+2y$

On the left, the 2y cancel. Simplify the right:

$x=2y+3$

And we're done!

The population in thousands of people of a city is approximated by the function P(t) = 1200(2)0.1038twhere t is the number of ye

asambeis [7]

The population of the group in 2019 is 2,134,000 people

Let P represent the population in thousands of people in the year t after 2011

Given the equation:

$P=1200(2)^{0.1038t}$

a) The population of the group in 2019, that is t = 8(2019 - 2011):

$P=1200(2)^{0.1038*8}=2134$

b) The population of the group in 2029, that is t = 18(2029 - 2011):

$P=1200(2)^{0.1038*18}=4382$

The population of the group in 2019 is 2,134,000 people

What is the equation of the line shown in this graph? <br><br>any links will be reported<br><br>

Blizzard [7]

Answer:

y = 1

Step-by-step explanation:

Slope is written in the form y=mx+b. Where m is the slope and b is the y-intercept.

When there isn't a slope, as in the line is flat and it isn't moving up or down, you wouldn't write anything for it. You would just write y equals the y-intercept (y = b).

Likewise, if the y-intercept is at (0,0), then you'd only write y equals the slope (y = mx).

Hopefully this makes sense :)

Btw, I also answered in the main comments earlier, so you can check that out as well.
