IrinaK [193]

Answer:

-138

Step-by-step explanation:

Distance between midpoint and point (-100) = -100 - (-119)

                                                      = 19

Since the [distance between the midpoint and point (-100)] and the [distance between the midpoint and point A] is the same, the distance between the midpoint and point A is also 19. You already know the midpoint is at -119. Since the midpoint is lower than point (-100), point A should be lower than point (-100).

Point A = -119 - 19

Point A = -138

Find lim x→3 sqrt 2x+3-sqrt 3x/ x^2-3x. you must show your work or explain your work in words plsss I need help
sineoko [7]

I'm assuming the limit is supposed to be

\displaystyle\lim_{x\to3}\frac{\sqrt{2x+3}-\sqrt{3x}}{x^2-3x}

Multiply the numerator by its conjugate, and do the same with the denominator:

\left(\sqrt{2x+3}-\sqrt{3x}\right)\left(\sqrt{2x+3}+\sqrt{3x}\right)=\left(\sqrt{2x+3}\right)^2-\left(\sqrt{3x}\right)^2=-(x-3)

so that in the limit, we have

\displaystyle\lim_{x\to3}\frac{-(x-3)}{(x^2-3x)\left(\sqrt{2x+3}+\sqrt{3x}\right)}

Factorize the first term in the denominator as

x^2-3x=x(x-3)

The x-3 terms cancel, leaving you with

\displaystyle\lim_{x\to3}\frac{-1}{x\left(\sqrt{2x+3}+\sqrt{3x}\right)}

and the limand is continuous at x=3, so we can substitute it to find the limit has a value of -1/18.

In the figure, x is an exterior angle to triangle ABC. (a) Explain why x is equal to the sum of the measures of the two nonadjac
earnstyle [38]

Hello from MrBillDoesMath!

Answer:

a) See Discussion below

b) Don't know what "m" refers to

Discussion:

Part a)

A triangle contains 180 degrees.

A + B + C = 180   (*)

where A is the angle inside the triangle.

From the diagram

B +C =   62 + 78 = 140

Substituting this in (*) gives

A + (140) = 180      => subtract 140 from both sides

A = 180 - 140 = 40

Now a line has 180 degrees so x + A = 180. But A = 40 (shown above) so x+ 40 = 180, or x = 140. That is, x  = 140 - the sum of the measures of the two nonadjacent interior angles

Part b)

I can't answer this part is it is unclear what "m" refers to. Sorry.

Thank you,

MrB
