M is the midpoint of AB, AM=2x+3, and AB= 8x-10. Find MB

Answers

I’m not sure if this is correct but I think the answer is 7.4 correct me if I’m wrong.

Explanation:

In order to find this answer I simply tried getting x by it self

8x-10 = 2x+3

then subtracted 2 from both sides (F.Y.I choose to start from the the left since 2 is lower then 8) the 2x= -2x cancel then if subtracted 8x from -2x you should get 6x
From there it should be
6x-10=3

Add 10 from both sides

Then your left with 6x=13

Now for this answer I obviously got a decimal and I’m not sure how I would go about rounding so I just rounded it to the nearest tenth.

After rounding 2.166666666666667

I was left with 2.2

From there I plugged it into the the AM formula

in the question M is the midpoint of AB so AM is congruent to MB AM=MB

AM=2x+3 MB=?

if you plug 2.2 in replace of x

2(2.2)+3 it should equal 7.4.

I hope I’m right, truly sorry if I’m not! I’m a freshie on the job! Good luck wishes!

The base of a triangle is 2 feet less than its height. Its area is 12 square feet. Find its base and height.

Answers

Answer:

Height of the triangle is 6 feet and base of the triangle is 4 feet.

Step-by-step explanation:

Area of a triangle is given by the formula,

Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

Let the height of triangle = h feet

Since, base of the triangle is 2 feet less than its height then base of the triangle = (h - 2) feet

Area = [tex]\frac{1}{2}h(h-2)[/tex]

[tex]12=\frac{1}{2}h(h-2)[/tex]

h² - 2h - 24 = 0

h² - 6h + 4h - 24 = 0

h(h - 6) + 4(h - 6) = 0

(h + 4)(h - 6) = 0

h = -4, 6 feet

Since height of the triangle can not be negative, therefore, height of the triangle = 6 feet.

And base of the triangle = (h - 2) = 6 - 2

                                         = 4 feet

Height of the triangle is 6 feet and base of the triangle is 4 feet.

then,

5x+4y=39---> plug y in to the function

5x+4(6)=39

5x+ 24=39

Solve 2x + 3y = 11 and 2x - 4y = -24 and hence find the value of 'm' for which y=mx+3.

Answers

Answer:

m=-1

Step-by-step explanation:

2x+3y=11............. (eqn 1)

2x-4y=-24...........(eqn 2)

Subtract eqn 1 from eqn 2

7y=35

y=5

Substitute for y in eqn 1

2x+3(5)=11

2x+15=11

2x=11-15

2x=-4

x=-2

y=mx+3

5=-2m+3

5-3=-2m

2=-2m

m=-1

Answer:Here,

2x+3y=11..........(i)2x-4y= -24......... (ii)

Subtracting (ii) from (i),we get

2x+3y=11

- 2x+4y=24

___________

7y =35

y=5

Substituting y = 5 in (i) we get

2x+3×5=11

or,2x +15 =11

or,2x = 11- 15

or,x= -2

Now,

We know,y=mx+c

5=m ×(-2) +3

or,2=m×(-2)

or,2/-2 =m

m= -1

if EF bisects CD, CG =5x-1, GD = 7x-13, EF = 6x-4, and GF =13, find EG

Answers

Greetings from Brasil....

As stated in the statement of the question, EF is a bisector of CD, so point G is the median point of CD, so CG = GD

5X - 1 = 7X - 13

X = 6

EF = EG + GF

6X - 4 = EG + 13      x = 6, so

6·6 - 4 = EG + 13

EG = 19

(see attachment)

A line segment is also a line but the line with finite length and having fixed endpoints. The length of the line segment EG is 19 unit.

What is a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

Given that EF bisects CD at point G, therefore, the line segment CD will be divided into two equal parts, CG and GD. Therefore, we can write,

CG = GD

5x - 1 = 7x - 13

-1 + 13 = 7x - 5x

12 = 2x

x = 12/2

x = 6

Further, the length of segment EG will be,

EG = EF - GF

     = 6x - 4 - (13)

     = 6x - 4 - 13

     = 6x - 17

     = 6(6) - 17

     = 36 - 17

     = 19

Hence, the length of the line segment EG is 19 unit.
