Answer:

To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (≥ or ≤), fill in the circle. If the sign does not include equal to (> or <), leave the circle unfilled in.

A city planner is rerouting traffic in order to work on a stretch of road. The equation of the path of the old route can be desc

earnstyle [38]

Answer: D

Explanation:

The equation of a line in the point slope form is expressed as

y - y1 = m(x - x1)

where

m represents slope

x1 and y1 represents coordinates of the point that the line passes.

From the information given, the equation of the path of the old route is

y = 2x/5 - 4

Recall, the equation of a line in the slope intercept form is expressed as

y = mx + c

By comparing both equations,

slope, m = 2/5

If two lines are parallel, it means that they have the same slope. Given that the new route is to be parallel to the old route and will go through point (Q, P), then

m = 2/5

x1 = Q

y1 = P

The equation of the new route be

y - P = 2/5(x - Q)

Find the midpoint of the segment with endpoints at A(3, 11) and B(7,3).

bonufazy [111]

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(3, 11) and B(7,3)

The midpoint is

$M = ( \frac{3 + 7}{2} \: , \: \frac{11 + 3}{2} ) \\ = ( \frac{10}{2} \: , \: \frac{14}{2} )$

We have the final answer as

Hope this helps you

How do you know where to put the constant when finding general solutions for differential equations?

Norma-Jean [14]

Let's suppose we want to solve $y'=y$ with $y(0)=2$ . Separating variables and integrating, we get

$\displaystyle\int\dfrac{\mathrm dy}y=\int\mathrm dx\implies\ln|y|=x+C\implies y=e^{x+C}$

Leaving the solution in this form, the initial condition gives

$2=e^{0+C}=e^C\implies C=\ln2$

This means the solution is $y=e^{x+\ln2}$ .

Now if we were to write $y=e^{x+C}=e^xe^C=Ce^x$ , then we would have found

$2=Ce^0\implies C=2$

so that the solution would have been $y=2e^x$ .

But these two solutions are the same, since $y=e^{x+\ln2}=e^xe^{\ln2}=2e^x$ . So we get the same solution regardless of where we place $C$ , despite getting different values for $C$ .
