Answer:
x > 0
Step-by-step explanation:
Since there is an open circle at x = 0, then x cannot be equal to zero.
The line to the right of x = 0 is shaded meaning that x has values greater than zero.
x > 0 ← is the inequality represented on the number line
Answer:
28 is the answer
Step-by-step explanation:
in an arithmetic sequence nth term An is given by the equation

where A1 is first term and d is common difference. thus from the question we have

Answer:
? = 13
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
?² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )
? =
= 13
Answer:
Total revenue by the toll bridge = $45
Step-by-step explanation:
Total vehicles crosses the bridge = 30
Number of passenger cars = 60 % of all vehicles =
= 18
Other vehicles = 30 - 18 = 12
Charges for one passenger cars = $1.00
Thus total Revenue by the passenger cars = 18 × 1 = $18
Charges for other vehicles = $2.25
Total revenue by other vehicles = 2.25 × 12 = $27
Thus the total revenue from the toll bridge = 18 + 27 = $45
-8x-8y=0 (divide both sides by -8, you get:) x+y=0, x=-y
-8x2y=-20 (divide both sides by -16:) xy=20/16=5/4
plug the first simplified equation into the second one,
-y²=5/4...This does not have a solution, are you sure you typed the second equation correctly?
