Describe and correct the error in finding DC
sleet_krkn [62]

Answer:

DC = 2

Step-by-step explanation:

The wrong equation was used.

The right equation to use based on the midsegment theorem of a trapezoid is:

MN = ½(AB + DC)

MN = 8

AB = 14

Substitute

8 = ½(14 + DC)

Multiply both sides by 2

8*2 = ½(14 + DC)*2

2*8 = 14 + DC

16 = 14 + DC

16 - 14 = 14 + DC - 14

2 = DC

DC = 2

Gavin needs $80 to buy a fish tank. He has saved $8 and plans to work as a babysitter to earn $9 per hour. Which inequality show
gavmur [86]

Answer:

<h2>n>8</h2>

Step-by-step explanation:

Step one:

given data

needed amount= $80

the amount already saved= $8

earnings per hour= $9

let the number of hours worked be n

and let y represent the total

the situation represented linearly is

y=mn+c

Step two:

substituting our data to find n

9n+8>80

9n>80-8

9n>72

divide both sides by 9

n>72/9

n>8

Therefore he must work a minimum of  8houees

Find b, if a is (5, -3) and m (-4, 2) is the midpoint of ab
Dennis_Churaev [7]
We were given the points, A(5,-3) and the midpoint of AB, M(-4,2).

Let point B have coordinates (c , d).

Then the midpoint of A(5, -3) and B(c,d)


= ( \frac{5 + c}{2}    \:  \:  \:  \frac{ - 3 + d}{2} )
Now let us compare to the given midpoint M(-4, 2).

We can then write the following equations for the corresponding coordinates.

Comparing x coordinates, we have;

\frac{ 5 + c}{2}  =  - 4
Multiplying both sides of the equation by 2 gives,

5+c = 2(-4)

Simplifying the right hand side gives,

5 + c = -8

Grouping like terms, we have,

c = -8 - 5

This simplifies to,
c = -13


Comparing y coordinates we have,

\frac{ - 3 + d}{2}  = 2
Multiplying through by 2 gives,

-3 + d = 2(2)

This means that,

-3 + d = 4

Making the subject we have,

d = 4+3

This implies that,

d = 7

Hence the coordinates of B are (-13,7).
