Answer:
The two equations are y=x+4 and y=2x+5.
Step-by-step explanation:
Given that (-1,3) is solutions of the system of two linear equations.
Let y=mx + c be the generalized equation of line having slope m and y-intercept c.
For different values of m and c, there are corresponding linear equations.
As the lines are passing through the point (-1,3), so, pot x=-1 and y=3 in the generalized equation, we have
All the real values of c and m which satisfy equation (i) are the desired linear equations.
As we required only two linear equations, take any two values of c and m.
For c=4 and m=1 (satisfying equation (i))
and for c=5, m=2
Hence, the two equations are y=x+4 and y=2x+5.
Answer:
The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.

Answer: 20/12
Step-by-step explanation: In order to get a 12 in the denominator
of 5/3, we multiply top and bottom of 5/3 by 4 to get 20/12.
So 20/12 is an equivalent fraction.
