The relationship between x and y can be written as y = mx , where m is a constant. If y = 17 when x =a , what is the value of y when x = 2a ?
Hint:
Hint:
- Linear equation is an equation whose degree is one.
The correct answer is: 34
Explanation:
- We have given relationship between x and y can be written as y = mx .When x = a ,
y =17
- We have to find the value of y when x = 2a
Step 1 of 1:
The relationship between x and y can be written as y = mx.
When x = a , y = 17
Ie ,
y = mx
17 = ma
Now when we put x = 2a
We will get
y = mx
y = m(2a)
y = 2ma
Since, ma =17
2ma = 2(17)
= 34
Hence, Value of y will be 34.
