It’s D, E. this is because an obtuse angle is an angle that is between ninety degrees and 180 degrees. anything smaller would be an acute angle and anything larger would be a reflex angle.
hope this helps :)

Point B is the midpoint of point C and D. If CB is 14in, what is CD and BD?
stich3 [128]

Answer:

BD = 14\ in

CD = 28\ in

Step-by-step explanation:

Given

CB = 14in

B as midpoint

Required

Determine CD and BD

<em>Since B is the midpoint, then the two line segments (CB and BD), we have the following relationships:</em>

<em></em>CB = BD

CD = CB + BD

Reorder the first equation

BD = CB

Substitute 14 for CB

BD = 14\ in

Taking the second equation into consideration

CD = CB + BD

CD = 14 + 14

CD = 28\ in

How do you substitute math 3x+y=-14 and 2x-y=-19 step by step
anastassius [24]

Answer:

x=-33/5 y=29/5

Step-by-step explanation:

Let's solve your system by substitution.

3x+y=−14;2x−y=−19

Solve

3x+y=−14 for y:

3x+y=−14

3x+y+−3x=−14+−3x(Add-3x to both sides)

y=−3x−14

Next is to substitute −3x−14 in for y 2x−y=−19:

2x−y=−19

2x−(−3x−14)=−19

5x+14=−19(Simplify both sides of the equation)

5x+14+−14=−19+−14(Add -14 to both sides)

5x=−33 Dived both sides by 5

5x/5=-33/3

x=−33/5 since you can't dived and a fraction is another form of division you keep it this way.

Step: Substitute -33/5 for x in y=−3x−14:

y=−3x−14

y=−3(-33/5)-14

y=29/5

(Simplify both sides of the equation)(since you can't dived and a fraction is another form of division you keep it this way.)

So

x=-33/5 and y=29/5

Pls mark brailest this took me a long time to write out lol. Hope this truly helps! Send a heart if so, so I can keep spreading the help!

Write two irrational numbers between 1/5 and 2/5​
Marina CMI [18]

Answer:

Step-by-step explanation:

First make all the fractions into decimals

1/5 = 0.2

2/5 = 0.4

As we know non terminating numbers are irrational so make up any non terminating number between 0.2 and 0.4

Like 0.3454672438700894......

Or 0.27435847454706.....

Options are infinite

If (k,6k) and (3k,10k) are two points on the graph of a line and K is not equal to 0, what is the slope of the line?
Nataliya [291]

Answer:

Step-by-step explanation:

slope = y2-y1/x2-x1

Given the coordinates (k,6k) and (3k,10k)

x1 = k

y1 = 6k

x2 = 3k

y2 = 10k

Substitute

slope = 10k-6k/3k-k

slopw = 4k/2k

slope = 4/2

slope  = 2

Hence the slope of the line is 2
