Answer:

1) Option B is correct.

2) None option is correct.

Step-by-step explanation:            

1) To find : Which ordered pair is a solution of the equation y=4x?

Solution :

To check the ordered pair we have to substitute all points which satisfy the equation is the required point.

A) (1,3)

3=4(1)

3\neq 4

Not true

B) (-1,-4)

-4=4(-1)

-4= -4

True

C) (-4,-1)

-1=4(-4)

-1\neq -16

Not true.

D) (1,-4)

-4=4(1)

-4\neq 4

Not true.

Therefore, Option B is correct.

2) To find : Which ordered pair is a solution of the equation y=-7x+2?

Solution :

To check the ordered pair we have to substitute all points which satisfy the equation is the required point.

A) (1,2)

2=-7(1)+2

2\neq -5

Not true

B) (8,-52)

-52=-7(8)+2

-52\neq -54

Not true

C) (5,-35)

-35=-7(5)+2

-35\neq -33

Not true.

D) (1,-7)

-7=-7(1)+2

-7\neq -5

Not true.

Therefore, None option is correct.

Substitute in the values and solve.

1) B

For A:

3 = 4(1)

<u>This is NOT true.</u>

For B:

-4 = 4(-1)

<u>This IS true.</u>

For C:

-1 = 4(-4)

<u>This is NOT true.</u>

For D:

-4 = 4(1)

<u>This is NOT true.</u>

2) None. Possible solutions: (0,2) (1,-5)

For A:

2 = -7(1) + 2

2 = -7 + 2

<u>This is NOT true.</u>

For B:

-52 = -7(8) + 2

-52 = -56 + 2

<u>This is NOT true.</u>

For C:

-35 = -7(5) + 2

-35 = -35 + 2

<u>This is NOT true.</u>

For D:

-7 = -7(1) + 2

-7 = -7 + 2

<u>This is NOT true.</u>

bill is replacing his 15ft long by 12 ft wide deck. his new deck will add 5 feet to the length and 4 feet to the width. if a dra
Ira Lisetskai [31]

The dimensions i.e. length and width of the deck in the drawing is 8 and 6.4 inches respectively.

Given that the length of the previous deck = 15 feet

The width of the previous deck = 12 feet

Since the new deck will add 5 feet to the length and 4 feet to the width,

The length of the new deck = 15 + 5 = 20 feet

The width of the new deck = 12 + 4 = 16 feet

Also given that a drawing of the new deck uses a scale of 1 inch = 2.5 feet.

So, The length of the deck in the drawing = 20/2.5 inches = 8 inches

The width of the deck in the drawing = 16/2.5 inches = 6.4 inches

Therefore, the dimensions i.e. length and width of the deck in the drawing is 8 and 6.4 inches respectively.
