Answer:

Step-by-step explanation:

Animal Person

y = 5.4x + 34 y = 12x + 8.5; where y - weight, x - years

looking for when weight (y) is the same, so we need

animal weight (y) = person weight (y)

5.4x + 34 = 12x + 8.5

34 = 6.6x + 8.5

25.5 = 6.6x divide both sides by 6.6

x = 3.86 years

not sure if you need your answer in decimal or what, but you can adjust accordingly.

Part A: Explain why x = 6 makes 4x − 5 ≤ 19 true but not 4x − 5 < 19. (5 points)

vovikov84 [41]

This solution shows that 6 is included in the solution due to the equal sign and not true for the inequality 4x − 5 < 19 since 6 is excluded

<h3>Inequality expression</h3>

Inequalities are equation not separated by an equal sign

Given the inequality expression

4x − 5 ≤ 19

4x ≤ 19 + 5

4x ≤ 24

x≤ 6

This solution shows that 6 is included in the solution due to the equal sign and not true for the inequality 4x − 5 < 19 since 6 is excluded

Given the equation

4x + 3 = 23

4x = 23 - 3

4x =20

x = 5

Hence 5 is the solution from the given set
