3. Sophie solved the inequality as shown. Explain Sophie's error
and give the correct solution to
the inequality.
-5(x - 1) > -7x + 19
-5X - 5 >-7x +19
2x - 5 > 19
2x > 24
X>12

After she distribute the and by , the after you get , she put a negative instead of a positive , and would be written as.

Step-by-step explanation:

Solve the inequality for the correct solution:

-Use Distributive Property:

-Take and add it to :

-Subtract to both sides:

-Divide both sides by :

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
