That's a tricky one because x is a function of y but y isn't a function of x.
(x, x²) is a perfectly good relation.
I'm not totally sure but I'd
Answer: B
D is the other answer that may be accepted but knowing teachers, I'd go with B.
Answer:
45 yards and 176 yards
Step-by-step explanation:
Perimeter of a rectangular playing field = 2(Length + width)
P = 2(L+W)..................... Equation 1
From the question,
Let the width of the rectangular playing field = x yards,
The the Length = 4x-4 yards.
Given: P = 442 yards.
Substitute these values into equation 1
442 = 2(4x-4+x)
442/2 = 5x-4
221 = 5x-4
5x = 221+4
5x = 225
x = 225/5
x = 45 yards.
Width = 45 yards.
Length = (45×4)-4 yards = 176 yards
Hence the dimensions of the playing field are, 45 yards and 176 yards
Total cost of 1 hour of parking is $2.
Explanation:
Given graph represents parking fees at a mall parking lot.
x-axis represents the hour of parking.
y-axis represents the cost of parking.
In the coordinate (1, 2),
1 represents hour of parking and 2 represents cost of parking
Hence, the coordinate (1, 2) represents the total cost of 1 hour of parking is $2.
The image of the graph is attached below.
Answer:
Neither
Step-by-step explanation:
This questions only states
This is not a fucntion because there is no variable.
This is not a valid statement, because 11.1.07% is non-sensical.
Answer:
(x+5)/3
Step-by-step explanation:
Our value, x, is being increased by 5, so we just add 5. Then it is split 3 ways, so we just divide x+5 by 3 to get (x+5)/3
Hope this helps
