Answer:
x = -8
Step-by-step explanation:
Set the function f(x)=9-2x equal to 25, and then solve the resulting equation for x:
9 - 2x = 25.
Isolate the -2x term by subracting 9 from both sides:
-2x = 16
Finally, solve for x by dividing both sides by -2:
x = -16/2, or x = -8
Answer:
9 times 6
Step-by-step explanation
Because you multiply 9 times 6 because 9 miles every 6 days
Answer:negative case : 2.5x - 6.8 = -12.9
positive case : 2.5 - 6.8 = 12.9
step 2 : 6.8
step 3 : dividing by 2.5
step 4 : x = 7.88
Step-by-step explanation:
Answer:
c) subtraction property of order
Step-by-step explanation:
To get from line 1 to line 2, 3 was subtracted from both sides of the inequality. The "subtraction property of order" says you can do that without changing the order or the solution.
It should not be a surprise that when subtraction is involved, the associated property has "subtraction" in its name.
