Answer:
x = 144
Step-by-step explanation:
y α x
we introduce a constant 'k' when changing from α to =.
i.e y = kx
y = ⅓ when x = 12
Meaning, ⅓ = k * 12
⅓ = 12k
k = ⅓ ÷ 12
k = 1/36
If y = 4, x = ?
using the equation y = kx
4 = (1/36)x
x = 4 ÷ (1/36)
x = 4 * 36
x = 144
Answer:
I think 2+-1x+9y
Step-by-step explanation:
Just add the numbers that have the same variables
The new coords are (2,-3) the new y coord is -3
Are you sure that is a real question
Sandwiches are $5.25 Bowls are $3.50
4x+5y=38.50
3x+9y=47.25
