Explain how system 1 becomes equivalent to system 2.
system 1:
ax + by = c
lx + my=n
system 2:
(a + l)x + (8 + m)y = c+n
ax + by = c
a. the first equation in system 2 is the sum of the equations in system 1. the second equation in system 2 is the first equation in system 1.
b. the first equation in system 2 is the difference of the equations in system 1. the second equation in system 2 is the first equation in system 1.
c. the first equation in system 1 is the sum of the equations in system 2. the second equation in system 1 is the second equation in system 2.
d. the first equation in system 1 is the difference of the equations in system 2. the second equation in system 1 is the second equation in system 2.

Equivalent expressions are expressions that have the same value.

The true statement is: (a) The first equation in System 2 is the sum of the equations in System 1. The second equation in System 2 is the first equation in System 1.

The systems of equations are:

System 1

$\mathbf{Ax + By = C}$

$\mathbf{Lx + My = N}$

System 2

$\mathbf{(A + L)x + (8 + M)y = C + N}$

$\mathbf{Ax + By = C}$

When the equations of system 1 are added, we have:

$\mathbf{Ax + Lx + By + My = C + D}$

Factor out x and y

$\mathbf{(A + L)x + (8 + M)y = C + N}$

The above equation is the first equation of system 2.

While $\mathbf{Ax + By = C}$ is the second equation of the system

Hence, the true statement is (a)

$\left\{\begin{array}{ccc}(A+L)x+(B+M)y=C+N\\Ax+By=C\end{array}\right$

A.The first equation in System 2 is the sum of the equations in System 1. The second equation in System 2 is the first equation in System 1.

Step-by-step explanation:

$\underline{+\left\{\begin{array}{ccc}Ax+By=C\\Lx+My=N\end{array}\right}\qquad\text{add both sides of the equations}\\(Ax+Lx)+(By+My)=C+N\qquad\text{distributive}\\(A+L)x+(B+M)y=C+N$

Answer from: Quest

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
