Answer:

Step-by-step explanation:

2. Each time x goes up on the left side 6 is removed from the right side f(x)= F(-6)

3. slope is y = -1/2 x + 4 the formula is y = mx+b so -1/2 x and b is the number that touches the line for y which is 4.

4. every time an x is added on the left side 3 are added on the right side f(3)

Line L passes through the points (0, --3) and (6,9).<br> (a) Find the equation of line L.
valentina_108 [34]

Step-by-step explanation:

Given points are :

(0,\:-3)=(x_1,\:y_1) \:\&\: (6,\:9)=(x_2 ,\:y_2)

Equation of line in two point form is given as:

\frac{y -y_1 }{y_1 -y_2 }  = \frac{x -x_1 }{x_1 -x_2 }  \\  \\  \therefore \frac{y -( - 3)}{ -3  -9 }  = \frac{x -0 }{0 -6 }  \\  \\  \therefore \frac{y  + 3}{ -12}  = \frac{x  }{ -6 }  \\  \\  \therefore \frac{y  + 3}{ 2}  = \frac{x  }{1}  \\  \\  \therefore  \: y + 3 = 2x \\  \\  \huge \red{ \boxed{\therefore  \: 2x - y - 3 = 0}} \\ is \: the \: required \: equation \: of \: line.

Explain please and tell me how to do it ?
SCORPION-xisa [38]

The trick to calculating the area here is to subdivide the diagram into smaller parts. For example, there's a 3 cm-by-3cm square. The rectangle is 4 cm by 8 cm.. The triangle has a base of 5 cm and a height of 3 cm.

Total area = area of square + area of rectangle + area of triangle

= 9 cm^2 + 32 cm^2 + (1/2)(5 cm)(3 cm)

= (9 + 32 + 7.5) cm^2

= 48.5 cm^2 (total area of figure)

For chicken feed 12 divided by 8.40

$1.43 for 1 pound of chicken feed

For goat feed 75 divided by 60

$1.25 for 1 pound of goat feed

For dog feed 50 divided by 37.50

$1.33 for 1 pound of dog feed

For pig feed 80 divided by 62.80

$1.27 for 1 pound of pig feed

When reviewing all the answers per pound for feed, chicken feed is the most expensive per pound.

Hope this helps:)
