Answer:
6s + 8c ≥ 900
Step-by-step explanation:
The library has <em>at least</em> 900 square feet available. It means <em>900 or more</em>.
If s is the number of study cubicles and c is the number of computer stations, the total space occupied by them is 6s+8c. That space is 900 or more square feet, so our inequality is 6s + 8c ≥ 900
Answer:
Step-by-step explanation:
a
4x - 5y = -12
-x + 5y = 18
Add the equations together:
4x + -x = 3x
-5y + 5y = 0
-12 + 18 = 6
So now you have:
3x = 6
Divide both sides by 3:
X = 2
Now you have the value of x, replace x with 2 in one of the equations and solve for y:
4(2) -5y = -12
8 -5y = -12
Subtract 8 from both sides:
-5y = -20
Divide both sides by -5:
Y = 4
The solution is x = 2 and y = 4 which is written as (2,4)
