Step 1
Given; The equations in the elimination method are written in the standard form as ____
Step 2
Simultaneous linear equations can be solved using the elimination method. First of all, make sure that the equations are written in the standard form either Ax+By=C or Ax+By+C=0. In this method, we multiply both the equations with a non-zero number to make the coefficients of any one variable equal.
Thus the answer is; The equations are written in standard form as seen below
Answer:
k=8
Step-by-step explanation:
divide both sides by 11 to get nine
then subtract 1 from both sides to get
8
Answer:
a) π
b) 33.4
Step-by-step explanation:
C = πd
1) substitute 105 for C: 105 = πd
2) plug in approximate value of 3.14 for π: 105 = (3.14) d
3) isolate to solve for d: 105/3.14 = d
4) simplify: 105/3.14 ≈ 33.4
Answer:38.4
Step-by-step explanation:
We have
and
so the equation is indeed exact. So we want to find a function 
such that
Integrating both sides of the first equation wrt 
gives
Differentiating both sides wrt 
gives
So we have
or
