Mathematics
1 answer:
Dmitry_Shevchenko [17]3 years ago

Answer:

y = f/9

Step-by-step explanation:

Area of a floor in square yards = y = f/9

Area of a floor in square feet = f

The number that represents the area of the floor in square feet is 9 times the number representing the area in square yards. This makes sense because the ratio of yard to feet is 1 : 3 and the ratio of square yard to square feet is the same ratio but squared so 1 : 9.

If y represents the area in square yards and f the area in square feet.

y = f/9

Which is an equation of the line through (-1, -4) and parallel to 3x+y=5
kherson [118]

Answer:

<h2>         b)  y = -3x - 7</h2>

Step-by-step explanation:

3x + y = 5         {subtract 3x from both sides}

y = -3x + 5         ←  slope-intercept form

y=m₁x+b₁   ║   y=m₂x+b₂   ⇔    m₁ = m₂

{Two lines are parallel if  their slopes are equal}

y = -3x + 5    ⇒   m₁ = -3    ⇒    m₂ = -3

(-1, -4)  ⇒  x₁ = -1,  y₁ = -4

The point-slope form:

y - (-4) = -3(x - (-1))

y + 4 = -3(x + 1)

y + 4 = -3x - 3              {subtact 4 from both sides}

<h3><u>y = -3x - 7 </u><u>        ←    slope-intercept form</u></h3>

Find the value of x.​
Leona [35]

Answer:

\boxed{\text{\sf \Large 3}}

Step-by-step explanation:

Angles in a triangle add up to 180°

180-(24x+3+25x)

-49x+177

Angles on a straight line add up to 180°

-49x+177+150=180

x=3
