Answer: f(x) is just a fancy way of writing y in an equation
Step-by-step explanation:
Example: f(x)= 2x+4 is the same as y= 2x+4
Answer:
Advance tickets-$15
Same-day tickets-$20
Step-by-step explanation:
let x be the cost of advance tickets and y cost of same-day tickets:
Given that there were 40 advance and 25 same-day tickets for a total of $1100:
#Make x the subject in i and substitute in ii:
Hence, advance tickets cost $15 each while same-day tickets cost $20 each.
Let the function be y = ax + c.
For (-1,8), 8 = a(-1) + c → 8 = - a + c
For (5,6), 6 = a(5) + c → 6 = 5a + c
Subtract one from abother,
2 = - 6a => - 1/3 = a
Hence, 8 = - 1/3 + c → 23/3 = c
Relation is:
y = (-1/3)x + (23/3)
3y = - x + 23
3y = 23 - x
Answer:
so x = 4 and x = -2/3
Step-by-step explanation:
Solve for x using the Master Product:
3x^2-10x-8=0
we see 3*(-8) = -24 and 2 * (-12) = -24 and 2 + -12 = -10
so 3x^2 + 2x - 12x - 8 = 0
x (3x + 2) -4 (3x + 2) = 0
(x - 4)(3x + 2) = 0
so x = 4 and x = -2/3
A=πr^2
A=3.14(11^2)
A=3.14(121)
A=379.94 which is simplfied to 380
