The answer should be
c) (-2,5)
It is the only point that falls on the line and when you count the units from (-7,2) to (-2,5) it is 5 units and when you count the distance from (3,8) to (-2,5) you also get 5 units, proving that (-2,5) is in the middle of the line.
ANSWER: a=12 b=15
Explanation: (look at work below)
4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
<span>Two problems such as 150,000 + 150,000 = 300,001 and 500,000 - 200,000 = 300,000 could show that two problems can give the same result. A third could be 400,000 - 148,000 = 252,000 but rounds to 300,000 when rounded. All three give the same result when rounded to the nearest hundred thousand.</span>
B) 35/6 is the correct answer
Answer:
2n, 5n, n
2m, 6m
4n3
Letters are grouped together, except for when they have exponents. Numbers with the same letter and exponent can be grouped together though (ex. 4n3 and 9n3) Hope this helps!
