Answer:
0.5x+y= 8---------------1
Step-by-step explanation:
Given data
let the mango be x
and strawberries be y
So the equation for the cost is

Answer:
y = -1/2 + 2 (Slope intercept)
Step-by-step explanation:
Y-intercept is when the x-value is 0.
So the y-intercept is (0, 2)
To find slope, find two random points:
(0, 2) , (2, 1)
Slope (m) =ΔY/ΔX = -1/2 = -0.5
Equation of the line:
y = -0.5x + 2
or
y = -1/2 + 2
When x=0, y = 2
When y=0, x = 4
It is wrong c is the correct answer I think
Answer:
This equation has no solution
Step-by-step explanation:
if the same equation equals 2 different numbers then therefore there is no solution.
If y = cos(kt), then its first two derivatives are
y' = -k sin(kt)
y'' = -k² cos(kt)
Substituting y and y'' into 49y'' = -16y gives
-49k² cos(kt) = -15 cos(kt)
⇒ 49k² = 15
⇒ k² = 15/49
⇒ k = ±√15/7
Note that both values of k give the same solution y = cos(√15/7 t) since cosine is even.
