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>
Answer: Your question options are not legible but the inverse of the function is f-1(x) = (x + 2) / 2
Step-by-step explanation:
y = 2x + 2
Make x the subject of formula:
2x = y - 2
x = (y - 2) / 2
Now substitute y for x:
(x - 2) / 2
Y = (x - 2) / 2 is the inverse equation of the above graph.

Step-by-step explanation:
Answer: The simplified form of above expression is
Step-by-step explanation:
Since we have given that
We need to solve the above expression to get the simplified answer:
1) Take the L.C.M. of 10 and 3.
L.C.M. of 10 and 3 = 30
2) Make the denominator 30 for each of the fraction .
3) Take the difference between them:
Hence, the simplified form of above expression is
