Answer:
The advantages & disadvantages of tables,graphs and words have been explained below.
Step-by-step explanation:
The 3 major representation for finding patterns and making predictions are;
1.Tables
2. Graphs
3. Words
This means we want to find the advantages and disadvantages of using tables, graphs and words for finding patterns and making predictions.
1) Tables: Advantage is that we will be able to directly see the exact effect of the input variable on the output. While the disadvantage is that it's very difficult to see patterns.
2) Graphs: Advantage is that we can easily see the pattern of the representation. However the disadvantage is that we can't see the exact values arising from the effect of the input variable on the output.
3) Words: The advantage is that we can describe the data values in clear terms. However, the disadvantage is that we can't get exact values from just the words.
Answer:
<h2><em>
[2(x+y)-25]cm</em></h2>
Step-by-step explanation:
Let the height of their oldest sister isabella be z centimeters. Roger is x centimeters tall and Olivia is y centimeters tall.
If their oldest sister, Isabella, is 25 centimeters shorter than the double of the sum of Roger and Olivia's height, this can be expressed as shown;
First let us get the sum of Roger and Olivia's height;
The sum of Roger and Olivia's height = (x+y)cm
The double of the sum of their ages = 2* (x+y)cm = 2(x+y)cm
Now if Isabella, is 25 centimeters shorter than the double of the sum of their ages, the expression will be [2(x+y)-25]
<em>Since the height of isabella is z, the expression that model isabella's height will be expressed as z =[2(x+y)-25]cm</em>
y-intercept is -6 (0,-6) and the x-intercept is -3 (-3,0)
Step-by-step explanation:
x + 2x + 3x = 180°
6x = 180°
Therefore, x = 30°
2 x = 60°
3x = 90°
Hence, it is a right angled triangle.
