The system of equations has infinitely many solutions
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
-3x + 3y = 12 ------- eqn 1
y = x + 4 --------- eqn 2
We have to find the solution to the system of equations
We can use substitution method
Substitute eqn 2 in eqn 1
-3x + 3(x + 4) = 12
-3x + 3x + 12 = 12
-3x + 12 = -3x + 12
If we have terms with same terms on both sides of equal sign, then we have infinitely many solutions
Thus the system of equations has infinitely many solutions
The y-coordinates are the same, so the length of this horizontal line segment is the difference between the x-coordinates.
Length = 7 - (-5) = 12 units

Step-by-step explanation:
True:
Any letter can be used as a variable (yes)
Variables are used for numbers that haven't been defined yet (maybe)
All the rest are false

Answer:
k-5. The question seems incomplete though.
<span>1st year value =45$
2nd year value=45+2.80$=47.80$
3rd year value=47.8+2.80$=50.60$
4th year value=50.60+2.80=53.40$
5th year value=53.40+2.80=56.20$
ater 5 years value of share becomes 56.20$
or
share after 5 years= 45+4*2.80=45+11.20=56.20$</span>
