Answer:

Correct option: second one -> 24 square units

Step-by-step explanation:

First we need to find the length of each side of the trapezoid, and we do that finding the distance between points:

AB = sqrt( (-1 - (-3))^2 + (2 - (-2))^2) = 4.4721

BC = sqrt( (3 - (-1))^2 + (2 - 2)^2) = 4

CD = sqrt( (5 - 3)^2 + (-2 - 2)^2) = 4.4721

DA = sqrt( (-3 - 5)^2 + (-2 - (-2))^2) = 8

The points B and C have the same y-coordinate, and the points D and A also have the same y-coordinate, so they are the bases of the trapezoid.

The height of the trapezoid is the difference in y-coordinate of points B and A:

height = 2 - (-2) = 4

So the area of the trapezoid is:

Area = (BC + DA) * 4 / 2 = (4 + 8) * 2 = 24 square units

Correct option: second one

Answer:

Its B

Answer: 0

Step-by-step explanation: it would only be a different number if there’s an equation like y=2x 3

0000000000000000000000

Step-by-step explanation:

Answer:

2x - 3y = 18  (1)

5x + 9y = -10​   (2)

<=>

Multiply both sides of (1) by 5, and multiply both sides of (2) by 2, then:

10x - 15y = 90

10x + 18y = -20

Subtract (2) to (1):

=> 33y = -110 => y = -110/33

Substitute y back into (1):

=> 2*x - 3*(-110/33) = 18

=> 2*x + 10 = 18

=> 2*x = 8

=> x = 4

=> Solution: x = 4, y = -110/33

Hope this helps!

Answer: x=4 y= -10/3

Step-by-step explanation:

Look at the attachment. It should explain.

The value of JW is 14 units.

A triangle is a polygon with 3 sides. The area of a triangle with base b and height h is given by A = (1/2)bh.

Given that, JB is the median of the triangle and JW = 6x + 2 and JB = 10x + 1.

The distance between the centroid and a vertex of a triangle is 2/3 of the length of the median, therefore, it follows:

JW = (2/3)JB

Substitute the values:

6x + 2 = (2/3)(10x + 1)

18x + 6 = 20x + 2

2x = 4

x = 2

Substitute x = 2 into the expression for JW:

JW = 6(2) + 2

JW = 14

Hence, the value of JW is 14 units.

Answer:

3455.75

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

Starting with 50

Took out 20

50-20 = 30

Then the balance was 0

We need to subtract 30 to get to get to 0

30-30 = 0

Taking out 30

Withdrawing 30

Spending 30

All are ways of indicating taking out 30 dollars

Answer:

On Tuesday, Devon took 30 dollars out of his checking account.

Step-by-step explanation:

Starting with: $50        -        Ending with $0

Monday: took out $20 or in other words -20   50-20=30

Tuesday: undetermined, but since that was his last day, it would correspond with $0 so, he must've took out $30 and then ended up with none in the end.

30-30=0

So, he took 30 dollars out on tuesday.

The answer would look something like this:

[tex]\frac{2+-\sqrt{2^{2}-4(-3)(6) }}{2(-3)}[/tex]

Answer: X=3

Step-by-step explanation:

Answer: 140%

Step-by-step explanation:

STEP 1: FIND THE CHANGE IN # OF PEOPLE:

initial # of people: 144

final # of people: 346

change in # of people = (final - initial)

change in # of people = (346 - 144)

change in # of people = 202

STEP 2: FIND THE % CHANGE

202/144 = x/100

(100)(202/144) = x

100(1.4) = x

140% = x

Answer:

140 %

Step-by-step explanation:

(346-144)/144 * 100

(202/144) * 100

Answer:

g(n) = [tex]\frac{11+5n}{3}[/tex]

Step-by-step explanation:

Given

3m - 5n = 11

Rearrange making m the subject

Add 5n to both sides

3m = 11 + 5n ( divide both sides by 3 )

m = [tex]\frac{11+5n}{3}[/tex] , thus

m = g(n) = [tex]\frac{11+5n}{3}[/tex]

I used a graphing calculator.

Answer:

the first one

Step-by-step explanation:

slope: use rise-over-run theorem. the slope of the graph rises -2 for every 1 unit over, so slope is -2x

intercept: the line crosses the y-axis at y=3, hence +3

3.2t-2.4

Step-by-step explanation:

-3.6 - 1.9t + 1.2 + 5.1t

Combine like terms

-3.6+ 1.2  - 1.9t +5.1t

-2.4        + 3.2t

Answer:  3.2t-2.4

Step-by-step explanation:

First thing you need to do is do   -1.9t+5.1t= 3.2t. Then you do -3.6+1.2= -1.2.

Then put all this together and you get 3.2t-1.2. (do not do 3.2t+-1.2 this incorrect because we left the subtracting sign
