Answer:
51.3 km²
Step-by-step explanation:
The area formula is ...
A = 1/2r²θ . . . . where θ is the central angle in radians
A = 1/2(7 km)²(2π/3) = 49π/3 km² ≈ 51.3 km²
38×5 is 190
200-10 is the only thing that makes 190 therefore your answer is the last one!
hope this helped
X + y = 1.....multiply by -1
4x + y = -23
---------------
-x - y = -1 (result of multiplying by -1)
4x + y = -23
---------------add
3x = - 24
x = -24/3
x = -8 <====
x + y = 1
-8 + y = 1
y = 1 + 8
y = 9 <====
The graph represents a function.
You can tell if a graph is function or not by using the vertical line test.
If the line only passes one point of the y-axe, it is a function. But when the graph passes more than two points, it is not a function.
Answer:
x = 7/-p
Step-by-step explanation:
-(px - 2) = 9
-px + 2 = 9
-px = 7
x =
