Step-by-step explanation:
" A sales promotion entails the features via advertising and or a discounted price of a particular product or service"
Option C:
The solution of inequality 2x + y < 10 is (5, –3).
Solution:
Given inequality is 2x + y < 10.
Lets substitute the given points in the inequality and find the solution.
Option A: (6, –1)
2(6) + (–1) < 10
12 – 1 < 10
11 < 10
This is false because 11 > 10.
Therefore (6, –1) is not the solution of the inequality.
Option B: (1, 10)
2(1) + (10) < 10
2 + 10 < 10
12 < 10
This is false because 12 > 10.
Therefore (1, 10) is not the solution of the inequality.
Option C: (5, –3)
2(5) + (–3) < 10
10 – 3 < 10
7 < 10
This is true.
Therefore (5, –3) is the solution of the inequality.
Option D: (5, 5)
2(5) + (5) < 10
10 + 5 < 10
15 < 10
This is false because 15 > 10.
Therefore (5, 5) is not the solution of the inequality.
Hence Option C is the correct answer.
The solution of inequality 2x + y < 10 is (5, –3).
so to find 15% of 54,237, we use this equation: (x/54237) = (15/100) where x is the amount of income tax.
cross multiply: 100x = 813555
divide each side by 100 to isolate x: 8135.55
the truck driver will pay $8135.55
Answer
8 %( When we round off to the neaerest tenths we get 10%)
Step-by-step explanation
4/50*100
=4*2
=8%
Okay first make sure you change negative 8 to a positive 8.
Set the problem up 8 -11 -49 899 -2506
