The sum of two numbers is 61.The larger number is 4 more than two times the smaller number. What is the smaller number?
2 answers:
Smaller number = x
larger number = y
solve the system of equations by substitution:
(2x+4) + x = 61
3x+4 = 61
3x=57
x=19
Plug x into the top equation and solve for y:
y + (19) = 61
y = 42
A + b = 61 a > b a = 2b + 4 2b + 4 + b = 61 3b + 4 = 61 3b = 57 b = 19

Answer:
2
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(6 + 6) / (2 + 4)
12/6
= 2
So, the rate of change is 2
All others did not satisfy the inequality simultaneously except #4 and #6 For #4: 2 < 5(1) + 2 i.e. 2 < 7 (true) 2 >= 1/2(1) + 1 i.e. 2 >= 3/2 (true) For #6 2 < 5(2) + 2 i.e. 2 < 12 (true) 2 >= 1/2(2) + 1 i.e. 2 >= 2
