What situations would solve by graphing be your preferred choice? Give an example.
Damm [24]

Answer:

1) The solve by graphing will the preferred choice when the equation is complex to be easily solved by the other means

Example;

y = x⁵ + 4·x⁴ + 3·x³ + 2·x² + x + 3

2) Solving by substitution is suitable where we have two or more variables in two or more (equal number) of equations

2x + 6y = 16

x + y = 6

We can substitute the value of x = 6 - y, into the first equation and solve from there

3) Solving an equation be Elimination, is suitable when there are two or more equations with coefficients of the form, 2·x + 6·y = 23 and x + y = 16

Multiplying the second equation by 2 and subtracting it from the first equation as follows

2·x + 6·y - 2×(x + y) = 23 - 2 × 16

2·x - 2·x + 6·y - 2·y = 23 - 32

0 + 4·y = -9

4) An example of a linear system that can be solved by all three methods is given as follows;

2·x + 6·y = 23

x + y = 16

Brenda has 5/6 of a pie to divide evenly amount 4 people. what fraction of a pie does each person get
yulyashka [42]

The fraction of the pie Each person will get from Brenda = ( 5 / 24 ) of the pie.

Given,

Brenda has 5/6 of pie with her.

The total number of persons = 4

Now, the fraction of the whole pie each person will take :-

( Number of pie ) / ( total persons )

= ( 5 / 6) / 4

= ( 5 / ( 6 x 4 ) )

= ( 5 / 24 )

Therefore, the fraction of the pie each person get from Brenda = ( 5 / 24 )

o-na [289]

Answer:

\large \boxed{z = \dfrac{83}{6 - C - T}}

Step-by-step explanation:

\begin{array}{rccl}-Cz + 6z & = & Tz + 83 & \\6z -Cz - Tz &= & 83 & \text{Subtracted Tz from each side}\\z(6 - C - T)  & = & 83 & \text{Removed the common factor}\\z& = & \mathbf{\dfrac{83}{6 - C - T}} &\text{Divided each side by 6 - C - T}\\\end{array}\\\\\large \boxed{\mathbf{z = \dfrac{83}{6 - C - T}}}
