The given known values are: Length of 4 cm Width is unknown Perimeter is 34 cm Find the dimensions of the rectangle.   Since the geometric formula for perimeter is:
P= 2 (l + w)
L = 2w – 4 cm
W =?  
Derivation and solution:
34 = 2 (2w - 4) + 2w <span>
34 =  4w – 8 + 2w</span>
42 = 6w 42/6 = w
W = 7 cm  

34 = 2l + 2(7)
34 = 2l + 14
2l = 34 – 14
2l = 20
L = 20/2
L = 10 cm

Given a verbal description, how do you interpret key features of functions and graphs?
ArbitrLikvidat [17]

Answer:

A linear function can be written in the slope intercept form or a point slope form of a line. Where a table is given for values representing the function, the ordered pairs will represent points on the line.The gradient of the line is a ratio of rise to run from the table values.In slope intercept form, the gradient and initial value of the function are indicated.

For example in a function f(x)=mx+b , m is the gradient of the line and b is the y-intercept value of the function.

To find the slope, m, you divide the difference between y-values by the difference in corresponding x-values of any two points on the line.

A decreasing linear function has a negative slope; if m<0 then f(x)=mx+c is decreasing

An increasing linear function has a positive slope where m>0.
