No because x=4 and y=-5 and when you plug it in you get 5(4)+2(-5)=8 20+-10=8 and 10= does not work so it is not a possible solution.
21. Smith received 60% of the votes
Murphy received 1/3 or 33%
100% - (60% + 33%) = 100 - 93 = 7%......so where is the other 7% of the votes. The vote total should equal 100%
22. Food : 500/2000 reduces to 1/4......or 25%......or 0.25
Rent : 1200/2000 reduces to 3/5....or 60% ...or 0.6
Transportation : 300/2000 reduces to 3/20...or 15%..or 0.15
23. sum of the rows:
Food + rent + trans = 1/4 + 3/5 + 3/20 = 5/20 + 12/20 + 3/20 = 20/20 = 1
Food + rent + trans = 25% + 60% + 15% = 100%
Food + rent + trans = 0.25 + 0.6 + 0.15 = 1
The sums should all equal because the percent, decimals, and fractions are all the same, just in a different form
24. 14.5% = 0.145 = 145/1000 = 29/200
14.5 = 14.5 = 14 1/2 = 29/2
14.5% is less then 1
14.5 is greater then 1

Step-by-step explanation:
The linear function that maps the relation between kinetic energy and mass is given at the end of the question.
<h3>What is the kinetic energy of an object?</h3>
The kinetic energy of an object is given by the following formula:
E = 0.5mv².
In which:
- m is the mass of the object.
- v is the velocity of the object.
In this problem, we suppose a velocity of 2.5 m/s, hence the kinetic energy is:
E = 0.5m(2.5)² = 3.125m.
Hence the graph is plotted at the end of the answer.
