Substitue y=3x into the other equation to get 3x=-x+4. Solve this to get 4x=4 therefore x=1.
knowing this, y=3
For the transformation
the Jacobian is
with determinant
The vertices of the triangle in the 
-plane are
Then the integral is
Answer:
First one
Step-by-step explanation:
3s=5s-6
By representing the equation is written in the form y = ax + b .
The value of b is 8.
According to the question
A start-up company opened with 8 employees.
So, Number of employees = 8
At zero quarter = 8
The company’s growth plan assumes that 2 new employees will be hired each quarter
After 1 quarter = Number of employees + 2 new employees
After one quarter = 8 + 2 = 10
Equation is written in the form y = ax + b to represent the number of employees, y, employed by the company x quarters after the company opened
y = ax + b
10 = 2 × 1 + b
10 = 2 + b
Subtract 2 on both sides of the equation
b = 10 - 2
b = 8
The value of b is 8.
