It’s the Last one bcuz you have to divide y by the X and the last one all equal to 0.5
Answer: it will take 2.33 hours for the snow fall in both of the towns be equal.
Step-by-step explanation:
Let x represent the number of hours that it will take for the snow fall in both of the towns be equal.
A town accumulated 2 inches of snow and the depth is increasing by 6 inches every hour. This means that in x hours, the depth of snow in the town would be
6x + 2
A nearby town has accumulated 9 inches of snow and the depth is increasing by 3 inches every hour. This means that in x hours, the depth of snow in the town would be
3x + 9
For the snow fall in both of the towns be equal, the number of hours would be
6x + 2 = 3x + 9
6x - 3x = 9 - 2
3x = 7
x = 7/3 = 2.33 hours
Answer:
2, 400
Step-by-step explanation:
1) 25 times 40 for how many miles the shark has done, which is 1,000
2) Do 1000 divided by 25, which is 40, so 40 hours.
3) Do 40 times 60 for how many minutes the shark has swam, which is 2, 400.
Answer:
vertex = (1, - 9 )
Step-by-step explanation:
The x- coordinate of the vertex is at the midpoint of the zeros.
Given
f(x) = (x - 4)(x + 2)
Find the zeros by letting f(x) = 0 , that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 4 = 0 ⇒ x = 4
Then
= 
= 
= 1
Substitute x = 1 into f(x) for corresponding y- coordinate
f(1) = (1 - 4)(1 + 2) = (- 3)(3) = - 9
Vertex = (1, - 9 )
