Step-by-step explanation:
Answer:
k = 13
Step-by-step explanation:
substitute x = x + 5 into f(x) , that is
f(x + 5) = (x + 5)² + 3(x + 5) - 10 ← expand squared factor using FOIL
= x² + 10x + 25 + 3x + 15 - 10
= x² + 13x + 30
compare this with f(x + 5) = x² + kx + 30
for the 2 expressions to be equal , then k = 13

Step-by-step explanation:
From the information, we are told that Mrs. Elizondo runs around a 400-meter track. If she runs 4 laps, the total meters will be:
= 400 × 4
= 1600 meters
Since she uses a constant speed of 250 meter per minute. The number if minutes taken to complete the 4 laps will be gotten by dividing 1600 by 250. This will be:
= 1600 / 250
= 6.4 minutes
= 6 minutes + (0.4 × 60 seconds).
= 6 minutes 24 seconds
Answer:
3 1/3
Step-by-step explanation:
So first turn 1 1/2 into a improper fraction-- which is 3/2
Then divide- to divide you need to flip the fraction and multiply
so you get 5/1*2/3 which equals 10/3 which is equal to 3 1/3
