A company makes and sells customized yard signs. If you order 5 signs, they charge $72 which includes shipping. If you purchase
klemol [59]

The slope is of $13, which means that each new sign costs $13.

-----------------

A linear function has the following format:

y = mx + b

In which

  • m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.
  • b is the y-intercept.

-----------------

  • In the linear function in this problem, we have two points (x,y): (5,72) and (15,202).
  • The slope is given by the <u>change in y divided by the change in x</u>, thus:

m = \frac{202 - 72}{15 - 5} = 13

  • The slope is of $13, which means that each new sign costs $13.

Degger [83]

(5, 3)

x    y

Plug in:

x + y = 8

5 + 3 = 8

8 = 8

Plug in:

17(5) + 17(3) = 8

85 + 51 = 8

136 = 8

Answer - No, (5, 3) is not a solution to this system of equations.

A small square pyramid of height 6 cm was removed from the top of a large square pyramid of height 12cm forming the solid shown.
Semmy [17]

Answer:

15,872 mm³

Step-by-step explanation:

given:

A small square pyramid of height 6 cm was removed from the top of a large square pyramid of height 12cm forming the solid shown.

Find:

the exact volume of the solid

solution:

volume of square base pyramid = (base area)² * h/3

where total h = 12 cm

height of top pyramid (ht)= 6 cm

height of bottom pyramid (hb) = 6 cm

bottom volume =  total volume - the volume on top

so,

total volume = 1/3 (base area)² h

                     = 1/3 (8*8)² * 12

                     = 16,384 mm³

volume on top = 1/3 (top base area)² h

                         = 1/3 (4*4)² * 6

                         = 512 mm³

finally: get the bottom volume:

bottom volume =  total volume - the volume on top

bot. vol = 16,384 mm³ - 512 mm³

             = 15,872 mm³

therefore,

the volume of the cut  pyramid base = 15,872 mm³
