10. A freight train leaves a station and travels at a rate of 30 miles per hour. Two hours later, an express train leaves
the same station traveling in the same direction at a rate of 50 miles per hour. In how many hours will the express train
overtake the freight train?
Answers
Answer:
4 hours
Step-by-step explanation:
We can already assume that the freight train is 60 miles ahead of the express. If the freight is going at a constant of 30 mph and the express goes 50 mph then we can say that when the freight train has been gone for 6 and the express for 4 the express will have passed the freight. The reason as to why would be that 60 + 120 = 180 or 60 + (30 x 4) = 180 and 50 x 4 = 200 .
Sorry if that explanation doesn't make sense but I hope this helped.

Answer:
A
Step-by-step explanation:
First distribute the 3 and 5 on the equations
3(x + 2) = 5(x-8)
3x + 6 = 5x - 40
Subtract 3x on both sides and add 40 on both sides
46 = 2x

Step-by-step explanation:
The formatting is quite weird since there is no * for multiplication and only x's which can confuse people between the multiplication sign and the variable. In general, try to use * for multiplication in the future! :)
Evaluate inside the parentheses:
Assuming the x on top is multiplication and xy 3 meanings 3 times xy:
(4*2/3xy)^2
= (8/3xy)^2
= [8/(3)(4)(2)]^2
= (8/24)^2

Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then shift left by a units
• If a < 0 then shift right by a units
-------------------------------------------------
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Then
g(x) = [tex](\frac{1}{4}) ^{x-3}[/tex] + 5
is f(x) shifted 3 units right and 5 units up
Which statement about f(x) = x^2 + 16x + 3 is true
A. The function has a maximum value of 3
B. The function has a maximum value of 16
C. The function has a minimum value of -8
D. The function has a minimum value of -61
Answers
Answer:
D
Step-by-step explanation:
Given a quadratic function in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
• If a > 0 then minimum value
• If a < 0 then minimum value
For
f(x) = x² + 16x + 3
a = 1 > 0 then f(x) has a minimum value
The minimum is the value of the y- coordinate of the vertex.
The x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
Here a = 1 and b = 16 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{16}{2}[/tex] = - 8
To find the y- coordinate of the vertex, substitute x = - 8 into f(x)
f(- 8) = (- 8)² + 16(- 8) + 3 = 64 - 128 + 3 = - 61
Thus the function has a minimum value of - 61 → D
