I= Ishaan's age= 2C
C= Christopher's age
35 years ago means we have to subtract 35 from their current age. Ishaan minus 35 equals 7 times Christopher minus 35 years.
CHRISTOPHER'S AGE:
I - 35= 7(C-35)
substitute I=2C in for I
multiply 7 by all in parenthesis
2C - 35= 7C - 245
add 35 to both sides
2C= 7C - 210
subtract 7C from both sides
-5C = -210
divide both sides by -5
C= 42 Christopher's age
ISHAAN'S AGE:
I= 2C
substitute C=42 to find Ishaan's age
I= 2(42)
I= 84 Ishaan's age
CHECK:
Substitute answers in original equation
I - 35= 7(C-35)
84 - 35= 7(42-35)
49= (7*42)+(7*-35)
49= 294-245
49=49
Hope this helps! :)
Answer:
Yes
Step-by-step explanation:
2√3 − 2√3 is equal to 0. So what we are trying to find out is if 0 is a rational number. 0 IS a ratinol number as it can be expressed as a fraction of integers.

Answer:
The transformation that occurs from 
is compression by 3 units horizontally and shift of 4 units upwards.
Step-by-step explanation:
Given
Translation Rules:
If 
the function is compressed 
units horizontally.
If 
and 
the function stretches units horizontally.
If the function shifts units to the up.
If 
the function shifts units to the down.
Applying the rules to 
Step 1
[compressed 
units horizontally]
Step 2
∴
[shifts 4 nits up]
∴ The transformation that occurs from is compression by 3 units horizontally and shift of 4 units upwards.
