Answer:
The best estimate for the solution is the ordered pair 
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
using a graphing tool, the solution of the system of equations is the intersection point both graphs
The intersection point is 
therefore
The best estimate for the solution is the ordered pair 
Step-by-step explanation:
We need to say that
is equivalent to what.
We know that, (3)² = 9
So,

We can write 
And 
So,

So,
is equivalent to
.
Hence, this is the required solution.
Answer:
Estimating the difference of fractions and mixed numbers is similar to estimating sums. Round each fraction or mixed number and then subtract to find the estimate.

Answer:
a
Step-by-step explanation:
the transversal across two parallel lines causes the consecutive internal angles to be congruent according to the consecutive internal angles theorem.
