Y = mx + b
slope(m) = 6
(-3,5)...x = -3 and y = 5
now we sub and find b, the y int
5 = 6(-3) + b
5 = -18 + b
5 + 18 = b
23 = b
so ur equation is : y = 6x + 23
The cosine function with the given characteristics is:
f(x) = 3*cos(x/2 - pi).
<h3>
How to get the cosine function?</h3>
The general cosine function is:
f(x) = A*cos(kx + p)
Where A is the amplitude and p is the phase, then we know that:
A = 3
p = -pi
Then we have:
f(x) = 3*cos(kx - pi)
And the period is equal to 4pi, then we must have that:
k*(x + 4pi) - pi = k*x - pi + 2pi
k = 1/2
Then the function is:
f(x) = 3*cos(x/2 - pi).

The lowest value for y is 3, when x=2, so (2,3) is the vertex.
Answer
x - 15 = 18
Explanation
X is the variable that is required to get the answer 18
Answer:
Step-by-step explanation:
The total number of ways to draw 3 students is 7*6*5 = 210
Order does not matter. There are 3 students that don't play soccer.
P(3 don't play soccer) = 3*2 * 1 / 210 = 1/35 = 0.02857
