Answer:
{ y = 3x + 3
{ 3x - y = 3
B
(Just did the assignment 3/23/21)
Multiplying eqn no. two with 4 we add it up with eqn 1.
When
So, x = - 10/17 and y = - 42/17.
Answer:
Step-by-step explanation:
Find the volume of a sphere 12 yards a crossed
Answer:
input x = - 7
Step-by-step explanation:
A is modelled as y = 5x - 4
B is modelled as y = 3x + 8
We require output of A three times the output of B , then
5x - 4 = 3(3x + 8) ← distribute
5x - 4 = 9x + 24 ( subtract 9x from both sides )
- 4x - 4 = 24 ( add 4 to both sides )
- 4x = 28 ( divide both sides by - 4 )
x = - 7 ← input
The answer is b because if you look there is no Direct variation
