Answer:
21,120 feet
Step-by-step explanation:
1 yard is = 3 feet so you multiply 3 by 7,040
Which is 21,120
Answer: 21,120
Hope this helps!
Answer:
No for both
Step-by-step explanation:
If 2 x values that are the same but different y values for them then its not a function
Answer:
x = 
and y = 
Step-by-step explanation:
Known that he sum of angles on a straight line is 
. From the diagram;
2y + x + y =
x + 3y = ................ 1
Also,
2x + x + 2y =
3x + 2y = .............. 2
Using the elimination method, multiply equation 1 by 3 and equation 2 by 1
3x + 9y = 540 ............ 3
3x + 2y = ............. 4
7y = 360
y = 
y =
substitute the value of y in equation 1,
x + 3y =
x + 3(51.4) =
x + 154.2 =
x = - 154.2
x =
Thus, x = and y =
Answer:
(5,-2) or y=3(x-5)^2 -2
Step-by-step explanation:
Answer:
f(x) = 1/2x + 6
Step-by-step explanation:
So before we even look at the first given formula, let's use the second formula: f(x) = -5.
Plug this formula into the x:
0 <= -5 <= 7
Is this true? Is -5 greater than or equal to 0 and less than or equal to 7?
No, this is false.
So the formula, f(x) = -5, is not the graph of f.
That only leaves one possible option!
