Answer:
x=-5 or x=3
Step-by-step explanation:
when multiplying anything by 0, the answer will be zero
In this case, one of the two factors has to be equal to 0
start by splitting into
(x+5) = 0
solve the equation
subtract 5 from both sides
x = -5
now, repeat for the other binomial
x-3 = 0
add 3 to both sides
x=3
Answer:
x = 3, the error is that the -2x should be added.
Step-by-step explanation:
The -2x should be added to the left side.
3x - 7 = -2x + 8
3x + 2x = 8 + 7
5x = 15
x =3

See the answers in the explanation
Step-by-step explanation:
Lin runs for 29 seconds at 7.2 meters per second. What is her finish point?
time= 29 seconds
speed= 7.2 m/s
distance= speed*time
distance= 7.2*29
distance=208.8
m
Elena runs for 26 seconds and finishes at 240 meters. What is her velocity?
time= 26 seconds
distance= 240meters
velocity= distance/time
velocity= 240/26
velocity=9.23 m/s
Diego runs for 33 seconds at -6.1 meters per second. What is his finish point?
time= 33 seconds
velocity
distance=velocity*time
distance=33*6.1
distance= 33*6.1
distance=201.3
m
Andre runs for 38 seconds and finishes at -295 meters. What is his velocity?
time= 38 seconds
distance= 295m
velocity= distance/tim
velocity= 295/38
velocity= 7.76m/s
Answer:
f(t) = 15 + 160 + 1
Step-by-step explanation:
it said that t= 4 and because the t is after the 40 you would times 40 by 4 to get 160. Then you add them all up and there you go you got your velocity and speed.
Should’ve listened in class buddy
