Answer:

Part 1

The drawing of the quadrilateral is included here

Part 2

The area of the quadrilateral is 60.5 unit²

Step-by-step explanation:

Part 1

Please find attached the given drawing of the quadrilateral created with Microsoft Excel

Part 2

The given quadrilateral ABCD comprises of a trapezium AECD and triangle ABE

The height of the trapezium, h₁ = 4 units

For segment BC, we have;

The slope = (-5 - (-2))/(5 - (-4)) = -1/3

The equation of the line BC in point and slope form is y - (-5) = -1/3×(x - 5)

Which gives;

y = -1/3×(x - 5) - 5 = -x/3 + 5/3 - 5 = -x/3 - 10/3

The y-intercept is (0, -10/3)

The lengths of the opposite parallel sides of the trapezium AECD are;

a = 5 - (-2) = 7 and b = 7 - (-10/3) = 31/3

The area of the trapezium AECD = ((a + b)/2) × h₁ = ((7 + 31/3)/2) × 4 = 104/3 unit²

The height of triangle

The area of ABE, h₂ = 5

The base of triangle ABE = b = 31/3

The area of triangle ABE = 1/2 × b × h₂ = 1/2 × 31/3 × 5 = 155/6 unit²

The area of quadrilateral ABCD = The area of the trapezium AECD + The area of triangle ABE

∴ The area of quadrilateral ABCD = 104/3 unit² + 155/6 unit² = 60.5 unit².

Answer:

2x + y = 600

Step-by-step explanation

Answer:

1,200x + 600y or 2x + y= 600

Step-by-step explanation:

knowing that there are 600 cats and 2 times the amount of cats we will have 1,200 cats which is 1,200x + 600y

Answer:

5

Step-by-step explanation:

Because -5 is a negative number and the opposite of negative is positive and 5 is positive.

Final Answer: [tex]5[/tex]

Steps/Reasons/Explanation:

Write down [tex]-5 + x = 0[/tex] because this is our equation with [tex]-5[/tex] plugged in to get an additive inverse. We will have to add [tex]5[/tex] to both sides. This means our additive inverse is positive [tex]5[/tex].

Question: Which number is the additive inverse of [tex]-5[/tex]?

[tex]-5 + x = 0[/tex]

Step 1: Regroup terms.

[tex]x - 5 = 0[/tex]

Step 2: Add [tex]5[/tex] to both sides.

[tex]x = 5[/tex]

Step-by-step explanation:

When you take a number to the power of a fraction, you write it as the root of the denominator to the power of the numerator.  The denominator is the bottom number and the numerator is the top number.  

Answer:

B

Step-by-step explanation:

the 0.1 is rate of change decreasing and 10.1 is original amount

Answer:

True.

Step-by-step explanation:

Note the point values: (x , y) = (1 , 8) ∴ x = 1, y = 8

Plug in the corresponding numbers to the corresponding variables in the equation:

y > x + 5

(8) > (1) + 5

8 > 1 + 5

8 > 6

8 is greater than 6, ∴ y is greater than x + 5.

Answer:

yes it would

Step-by-step explanation:

x=1 + 5 is six

y=8

8 > 6

8 > 1

Answer:

m∠C = 54°, m∠CDB = 100°

Step-by-step explanation:

in ΔABC, m∠A= 37° and m∠B = 89°

The sum of all 3 angles in any triangle is 180° so

m∠C = 180-37-89 = 54°

m∠CDB = 180-80 = 100° because any line has a 180°angle

Final Answer: [tex]g = 1[/tex]

Steps/Reasons/Explanation:

Question: How do you solve [tex]-3 + 5 +6g = 11 - 3g?[/tex]

Step 1: Simplify [tex]-3 + 5 + 6g[/tex] to [tex]6g + 2[/tex].

[tex]6g + 2 = 11 - 3g[/tex]

Step 2: Subtract [tex]2[/tex] from both sides.

[tex]6g = 11 - 3g - 2[/tex]

Step 3: Simplify [tex]11 - 3g - 2[/tex] to [tex]-3g + 9[/tex].

[tex]6g = -3g + 9[/tex]

Step 4: Add [tex]3g[/tex] to both sides.

[tex]6g + 3g = 9[/tex]

Step 5: Simplify [tex]6g + 3g[/tex] to [tex]9g[/tex].

[tex]9g = 9[/tex]

Step 6: Divide both sides by [tex]9[/tex].

[tex]g = 1[/tex]

Answer:

14 i think

tbh, just guess and check

56/14=4 each student gets 4 lollipops

there are 14 students.

The ratio 4/6 is the same as 2/3 because they have the same proportion.

To find a ratio that is the same as 2/3, multiply or divide both the numerator and the denominator by the same non-zero number.

1. Multiplying by the same number:

  If you multiply both the numerator and the denominator of 2/3 by 2, you get:

= (2 × 2) / (3 × 2)

= 4/6

So, the ratio 4/6 is the same as 2/3.

2. Dividing by the same number:

  Divide both the numerator and the denominator of 2/3 by 3, you get:

= (2 ÷ 3) / (3 ÷ 3)

= 2/3

So, the ratio 2/3 remains the same.

In conclusion, the ratio 4/6 is the same as 2/3.

Answer:

El frente de la casa es 6 metros.

Step-by-step explanation:

El area de la casa está dada por el área de un rectángulo:

[tex]A = f*l = x (x+5) = 66[/tex]

En donde f es el frente = x , l es el largo = x+5 y A es el área = 66m²

Si la ecuación cuadrática que define el área del terreno viene dado por:

[tex] x^{2} + 5x - 66 = 0 [/tex]          

Resolviendo la ecuación cuadrática para x tenemos:

x₁ = -11 y x₂ = 6

Graphing ordered pairs is only the beginning of the story. Once you know how to place points on a grid, you can use them to make sense of all kinds of mathematical relationships.

You can use a coordinate plane to plot points and to map various relationships, such as the relationship between an object’s distance and the elapsed time. Many mathematical relationships are linear relationships. Let’s look at what a linear relationship is.
