A scientist is testing bacteria in a lab. The normal range for bacteria can be modeled using a compound inequality. The bacteria must be within 1.4 of the average level of 6.1 to be considered normal.

Choose the correct compound inequality to model this real-world situation.

answer: haha (: i’ll go see what it is

step-by-step explanation:

51-50

step-by-step explanation:

answer: the answer is ann

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
