Y ≥ -3x + 2
It will be good to draw a graph and read the solution from the graph
y = -3x + 2
for x = 0 → y = -3 · 0 + 2 = 2 → (0, 2)
for x = 2 → y = -3 · 2 + 2 = -6 + 2 = -4 → (2, -4)
Answer: A, C, E, F.
Answer:
176
Step-by-step explanation:
every 11 mm in the drawing equals 4m.
every 1 mm in the drawing equals 4/11 m
Actual size of school yard = 484*4/11 = 176m
Answer:
a =17.08
b = 16.97
Step-by-step explanation:
What are the values of a and b?
Using pythagoras therem';
Hyp^2 = opp^2 + adj^2
Get the value of b;
18^2 = b^2 + 6^2
324 = b^2 + 36
b^2 = 324 - 36
b^2 = 288
b = √288
b = 16.97
Get the value of a;
b^2 + 2^2 = a^2
288 + 4 = a^2
292 = a^2
a^2 = 292
a = √292
a= 17.09

Answer:
1/8 of the budget was left for other expenses.
Step-by-step explanation:
1/4 of the budget - buildings and maintenance.
Administrative personnel : 1/4 + 1/8 = 2/8 + 1/8 = 3/8 of the budget.
Therefore:
3/8 of the budget - administrative personnel.
Public safety : 3/8 - 1/8 = 2/8 = 1/4 of the budget.
For other expenses :
1 - ( 1/4 + 3/8 + 1/4 ) = 1 - ( 2/8 + 3/8 + 2/8 ) 1 - 7/8 = 1/8
Finally, 1/8 of the total budget was for the other expenses.
