Jack drove to the train station and back. It
took two hours less time to get there than
it did to get back. The average speed on
the trip there was 40 km/h. The average
speed on the way back was 24 km/h. How
many hours did the trip there take?
Answer:
8hoursStep-by-step explanation:
let the time taken to get back be x
so that the time needed to go is (x-2)
we know that speed= distance/time
therefore the speed for the return is 24 km/h.
distance (return)= 24*x
distance (return)=24x
therefore the speed to the station is 40 km/h.
distance (return)= 40*(x-2)
distance (return)=40x-80
We know that the distance is the same
24x=40x-80
24x-40x=-80
16x=80
divide both sides by 16
x=5
the time taken to get back is x=5hours
the time taken to is x-2=(5-2)= 3hours
the total trip takes 3+5= 8hours

Question 6(Multiple Choice Worth 1 points) (02.05 MC) Choose the table that represents g(x) = 4⋅f(x) when f(x) = x − 5. x g(x) 1 −4 2 −3 3 −2 x g(x) 1 −16 2 −12 3 −8 x g(x) 1 −20 2 −18 3 −16 x g(x) 1 −1 2 −2 3 −3
Answer: (b)
x g(x)
1 -16
2 -12
3 -8
If g(x) is 4*f(x), then we can find g(x) by multiplying 4 by x-5
g(x) = 4(x-5)
= 4x-20
Now we can plug in 1,2, and 3 for x to see which table makes sense.
g(1) = 4(1) - 20
= -16
g(2) = 4(2) - 20
= -12
g(3) = 4(3) - 20
= -8
hope this helps
Answer:
x g(x)
1 -16
2 -12
3 -8

Answer:
5*10^10
Step-by-step explanation:
10 to the power of 10 is 10^10.
10^10*9 is 90000000000
10^10*4 is 40000000000
90000000000-40000000000=50000000000

Find the equation of the line shown.
Given : A graph of linear equationis given to us.
To Find : The equation of the line .
Solution : Here we can see that the line passes through points ( 1 , 2 ) and ( 2 , 4). So , clearly here we can use Two - point form to find the equation of the line .
So , first point will be , ( 1 , 2 ) & second point will be ( 2 , 4 ) . So here ;

the question is 7a + 10 = 2a
Answer:
a = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 - 10 = 2a - 10
Simplify:
7a = 2a - 10
Subtract 2a from both sides:
7a - 2a = 2a - 10 - 2a
Simplify:
5a = -10
Divide both sides by 5 and simplify:
a = -2
Answer:
A = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 = 2a -10
Simplify the expression, 7a = 2a - 10
Subtract 2a from both sides next
7a - 2a = 2a - 10 - 2a
Subtract 7a - 2a
5a = -10
5a / 5 = -10/5
a = -2
Solve the equation for x.
-7(x - 2) + 5(3 - x) = 4x - 3
Answer:
x=2
Step-by-step explanation:
-7x+14+15-5x=4x-3
-12x+29=4x-3
-12x-4x=-29-3
-16x=-32
x=-32/-16
x=2
Answer: x=2
Step-by-step explanation:
Simplify the equation
-12+29= 4x-3
Subtract 29 from both sides
12x=4x-32
Subtract 4x from both sides (Simplify)
-16x=-32
Divide both sides by -16
