Answer:
The answer is B.
Step-by-step explanation:
To obtain the inverse of a relation you simply interchange the x and y coordinates of each pair.
Here:
(3,1) becomes (1,3)
(3,1) becomes ((1,3)
(7, -7) becomes (-7,7) and
(12, -15) becomes (-15, 12)
the answer is A

Answer:
quadratic monomial, quadratic trinomial, constant monomial, linear monomial, quadratic binomial, linear binomial.
Step-by-step explanation:
two quadratic trinomials each have a degree-2, degree-1, and degree-0 term. It is possible that the coefficients of all or some of the terms cancel each other while adding or subtracting the polynomials.
Answer:
Okay, so a bit of math is involved, along with steps.
Step-by-step explanation:
Kyra invested $400 at 3% for 3 years. meaning 3% of $400 is 12. 400+12=
Year 1: $412
3% of 412=12.23+412=
Year 2: $424.23
3% of 424.23=12.7+423.23=
Year 3: $435.93
Kyra made $35.93 in investments.
Lishsawn invested $500 at 4% for 2 years. Meaning, 4% of $500 is 20. 500+20
Year 1: $520
4% of 520=20.8+520
Year 2: $540.8
Lishawn made $40.8 dollars in investments. Meaning that Lishawn made $4.87 more dollars
Option B
2 times the length of Noah's bike ride was Mai's bike ride
<h3><u>Solution:</u></h3>
Given that Mai biked 7 and 1/4 miles today and Noah biked 
miles
We have to find how many times the length of Noah's bike ride was Mai's bike ride
Let "a" be the number that denotes how many times the length of Noah's bike ride was Mai's bike ride
From given information,
Distance biked by Mai = 
Distance biked by Noah = 
So to find how many times the length of Noah's bike ride was Mai's bike ride, we can frame a equation as:
"a" times distance biked by noah is equal to distance biked by mai
<em><u>Substituting the known values we get,</u></em>
Thus 2 times the length of Noah's bike ride was Mai's bike ride
