Step-by-step explanation:
4x -3y=-3
-4x -4x
-3y=-4x-3
Then divide by -3
Answer
Y=4/3x+1
Answer:
y = 7 ± 
Step-by-step explanation:
- 14y = -47
= 14y - 47
y = 7 ±
Answer:
5 eggs.
Step-by-step explanation:
Well, 3/4 of 12 is 9 and 5/6 of 12 is 10. So, 12 - 9 = 3 and 12 - 10 = 2
Therefore, Matthew has 5 eggs left over.
I hope I helped ^^
Answer: constant of variation k = 36 the variation equation, y = 36xz^3
Step-by-step explanation:
y varies jointly as x and the cube of z. This means that y varies directly as x and directly as z^3
In order to remove the "variation" symbol and replace it with "equal to" symbol, we will introduce a constant of variation, k
y = kxz^3
y=432 when x= 4 and z=3
We will substitute these values of x, y and z into the equation to determine the value of k
432 = k × 4 × 3
432 = 12k
k = 432/12 = 36
We will substitute the value of k into the equation. Substituting k = 36 into equation y = kxz^3
The equation becomes
y = 36xz^3
