Answer:

equation is 4x-4y= -16

Step-by-step explanation:

b = 4

x = -1

y = 3

so

x/a + y/b = 1

or, -1/a + 3/4 = 1

or, (-4 + 3a) = 4a

or, -4 = 4a - 3a

so, a = -4

now

x/a + y/b = 1

or, x/-4 + y/4 = 1

or, 4x-4y = -16

so

equation : 4x-4y = -16

I need help the question is what is the are of the composite figure
AlladinOne [14]

Answer:

Option 4

Step-by-step explanation:

Area of a trapezoid = \frac{1}{2}(b_1+b_2)h

Here, b_1 and b_2 are the bases and 'h' is the height between the bases.

Area of the composite figure = Area of two trapezoids given

                                                = \frac{1}{2}(12+12)14+\frac{1}{2}(25+31)11

                                                = \frac{1}{2}(24)(14)+\frac{1}{2}(56)(11)

                                                = 168 + 308

                                                = 476 square ft

Option 4 is the answer.

Freezer A measures 1 ft times 1 ft times 5 ft and sells for ​$300. Freezer B measures 1.5 ft times 1.5 ft times 4 ft and sells f
Sladkaya [172]

Answer:

Freezer A is better option as price per cubic foot is less for Freezer A

Step-by-step explanation:

Data provided in the question:

Measure of Freezer A = 1 ft × 1 ft × 5 ft

Measure of Freezer B = 1.5 ft × 1.5 ft × 4 ft

Price of Freezer  A = $300

Price of Freezer  B = $600

Now,

Volume of Freezer A = 1 ft × 1 ft × 5 ft

= 5 ft³

Volume of Freezer B = 1.5 ft × 1.5 ft × 4 ft

= 9 ft³

Now,

Price per cubic foot for Freezer A = $300 ÷ 5 ft³

= $60/ft³

Price per cubic foot for Freezer B = $600 ÷ 9 ft³

= $66.67/ft³

Hence,

Freezer A is better option as price per cubic foot is less for Freezer A

Use the image above to write a conjecture about regular polygons and lines of symmetry
Tatiana [17]
To find conjecture about regular polygon, use the formula \frac{360}{n}

Where, n = number of sides of the regular polygone

1) Triangle
n =3
So, Conjecture of the triangle = \frac{360}{3} = 120

2) Square
n =4
So, Conjecture of the square = \frac{360}{4} = 90

3) Pentagone
n = 5
So, Conjecture of the pentagon = \frac{360}{5} = 72

4) Hexagone
n = 6
So, Conjecture of the pentagon = \frac{360}{6} = 60.
