balandron [24]

Answer:

221 minutes

Step-by-step explanation:

His goal is 8 minutes or less for every mile during the marathon.

8 x 52 = 416

That gives him 416 total minutes to complete the marathon goal.

He already ran the first half in 195 minutes, so we do this to find the time for the other half:

416 - 195 = 221

He has 221 minutes in the second half of the marathon to meet his goal.

Which function represents transforming ƒ(x) = 3x with a reflection over the x-axis and a vertical shift of 4 units?
Oxana [17]

Answer:

D. h(x)=-3x+4

Step-by-step explanation:

we are given

f(x)=3x

Firstly, it is reflected over x-axis

we know that for reflection about x-axis , we can replace y as -y

we get

g(x)=-f(x)

g(x)=-3x

now, it is vertical shift up by 4 units

so, we can add 4 to y-value

we get

h(x)=g(x)+4

h(x)=-3x+4
