the critical points of a rational inequality are -1, 3, and 4. which
nd 4. which set of points can be tested to find a complete solution to the
inequality?
x = 1 and x = 3.5
x = -1, x = 3, and x = 4
x= -2, x= 2, and x = 5
x = -3, x = 1, x = 3.5, and x =5

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
