Let the function be f defined by f (x) = 12 - 5x

Mathematics

marissa [1.9K]3 years ago
7 0

(a) No

f(x) = 12 - 5x

f(0) = 12 - 5(0)

f(x) = 12 - 0

f(x) = 12

Hence,

f(0) is unequal to 0.

(b)

f(x) = 12 - 5x

f( - 1) = 12 - 5( - 1)

f( - 1) = 12 + 5

f( - 1) = 17

(c)

f(x) = 12 - 5x

f(x) = 6

6 = 12 - 5x

6 - 12 =  - 5x

- 6 =  - 5x

6 = 5x

\frac{6}{5}  = x

<h3>What is a Square ?</h3>

A square is a polygon with four sides and all the sides are equal and parallel and all the angle value is 90 degree.

(a) The 5x5 square  grid has 6 , 2 x 2 subgrids.

(b) the least value of n for which you can be certain that it will have a 2 x 2 subgrid of grey squares is 12

as it can be understood from the figure 2 that only the last square doesn't have a pair and the rest all does

more than that will be extra but 12 will be enough to make all the grey squares of 2 x 2 subgrid .
