Answer:

- 34

Step-by-step explanation:

Let the required number be x

Therefore, one less than a number = x - 1

(x - 1) \div 5 =  - 7 \\  \\  \frac{x - 1}{5}  =  - 7 \\ \\  x - 1 =  - 7 \times 5 \\  \\ x - 1 =  - 35 \\  \\ x = 1 - 35 \\  \\ x =  - 34

A line passes through the points (2,21) and (8,27). Write a linear function rule in terms of x and y for
tatiyna
We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19

a) We kindly invite to check the image attached below to see a detailed graph of the <em>piecewise</em> function.

b) The <em>piecewise</em> function is continuous.

<h3>How to understand a piecewise function</h3>

A <em>piecewise</em> function is a <em>conditional</em> combination of two or more functions, whose expression depends on which value of the domain is the function evaluated at.

a) The <em>piecewise</em> function described in the question is plotted on a graphing tool (i.e. <em>Desmos</em>), whose result is presented in the image attached below.

b) A function is <em>continuous</em> if and only if there is one value from range for every value of domain. The <em>piecewise</em> function is continuous as <em>linear</em> functions are continuous and the two functions of the <em>conditional</em> combination have the same value for x = 30.
