A and B have the same perimeter
Answer:
ok do I have to do something? or just because?
For the function
y = cos(1/2 x)
The x-intercept can be calculated by equating the function to zero and solving for x. So,
y = cos(1/2 x) = 0
1/2 x = arc cos 0
1/2 x = 90° +180°n
x =2 (90° +180°n)
x = 180° + 360°n
or converting to radians
x = (180° + 360° n)(π/180°)
x = π + 2π n
where n is any whole number
if n = 0
x = π
Therefore, the x-intercept is π or π+2π n
Answer:
A, D, E
Step-by-step explanation:
Substitute the x and y values into the equation. If the result does not equal 24, then that coordinate point is not on the graph of 3x+2y=24.
If youre writing an exprssion all you need to do is make variables and multiply by the given number A, C, and S will be our variables.
2A + 3C + 1S = Total cost for andrews family
4A + 2C = Total cost for Spencers family
Now, Does 2A + 3C + 1S = 4A + 2C
lets say A = 5 , C = 3 , and S = 2
2(5) + 3(3) + 1(2) = 4(5) + 2(3)
10 + 9 + 2 = 20 + 6
21 = 26
if this is your example then No, the spencers family spent more than the andrews family, youll have to do the math differently and may come up with a different answer if you were given values that you didn't give us, but this is how its done :)
Hope this helps!
