45•8=360 because there are 4 weeks in months and 2 months you get 8 weeks and just multiply 45 Tim's 8 to get 360 trays
Answer:
(3,3)
(-5,19)
Step-by-step explanation:
y= x^2 - 6
y=-2x + 9
Set the two equations equal to each other y=y
x^2 - 6 =-2x + 9
Add 2x to each side
x^2 +2x- 6 =-2x+2x + 9
x^2 +2x- 6 = 9
Subtract 9 from each side
x^2 +2x- 6-9 =9- 9
x^2 +2x- 15 =0
Factor the left hand side
What 2 numbers multiply to -15 and add to 2
-3 *5 = -15
-3+5 = 2
(x-3) (x+5) =0
Using the zero product property
x-3 =0 x+5 =0
x=3 x=-5
Now we find y for each x
x=3
y=-2(3) + 9 = -6+9 =3
(3,3)
x=-5
y=-2(-5) + 9 = 10+9 =19
(-5,19)
(t-4)(t+8)
Smallest:-8✨

Answers are when function is zero
And the vertex is solving like this:
t2+4t-32=0
Vertex: -b/2a
Vertex: -4/2= -2✨
now our t is -2 so—> solve it when t is -2 and the answer is (-2,-36)✨
Answer:
56 goals in 40 games
Step-by-step explanation:
I'll assume the 1.4 goals is the average per game.
(1.4 goals/game)*(40 games) = 56 goals in 40 games.
