As the variation is direct then we have the following expression:
From here, we clear the value of k.
For this we use the following data:
y = 144 when x = 4
Substituting values:
Clearing k we have:
Then, the function is:
When x = -5 we have:
Answer:
the value of y when x = -5 is:
b.
225
Step-by-step explanation:
For no. 1
y = x + 5 and y = 6
Now substituting
6 = x + 5
x = 6 - 5
x = 1
so choose ( 1 , 6)
For no. 2
y = - x - 3 and y = - 2
Now substituting
- 2 = - x - 3
x = - 3 + 2
x = - 1
so choose (- 1 , - 2)
Hope it will help:)
