Which of the options is a solution for the following system of inequalities
1 answer:
Answer:
(5, - 2)
Step-by-step explanation:
2x+y>3
x-y>1
2x + y > 3 - - - - (1)
x - y > 1 - - - (2)
Using trial and error method :
Using :
(5,-2)
2x + y > 3
2(5) + (-2) > 3
10 - 2 > 3
8 > 3 (true)
x - y > 1
5 - (-2) >1
5 + 2 > 1
7 > 1 (True)
For 0,5
2x + y > 3
2(0) + (5) > 3
0 + 5 > 3
5 > 3 (true)
x - y > 1
0 - (5) >1
-5 > 1
--5 > 1 (false)
Also, all other options do not hold true for bitb inequality statements, hence answer is (5, - 2)

Answer:
A = 4 units ^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 4) (2)
A = 4 units ^2
Because 1/3 = 4/12 so 7/12 is greater and 2/3 = 8/12 so it is greater than 7/12
A = 2lw + 2lh + 2hw
A = 2(12)(3) + 2(12)(5) + 2(5)(3)
A = 72 + 120 + 30
A = 222 cm squared
Hope this helps!! :)
First you have to set up your equation. 5x+80 and x+15.
