Answer:
$1.05
Step-by-step explanation:
The amount of money they should pay is 4.15+6.35+2*1.1+1.25 = $13.95
The change is 15-13.95=$1.05
Let the distance be x miles
Time = Distance / speed
Time taken by Mike to go to his friend's house = x / 40 hours
Time taken by him to return = x / 45 hours
Total time = x / 40 + x / 45 = 4 hours
= 9x + 8x = 1440 miles
17x = 1440
= x = 1440 ÷ 7
= x = 84.706
Time taken to return home = 84.706 /45= 1.882 hours .
Therefore , Mike took 1.882 hours to reach home .
Answer:
1
Step-by-step explanation:
-2(x-4)+1=7
First Distribute the -2.
-2x+8+1=7
Subtract the 8 and 1 from the whole equation.
-2x=-2
Divide both sides of the equation by -2.
x=1
I hope this helps!
Answer:
The minimum point is (4,-3)
Step-by-step explanation:
we know that
If the new equation is
y=f(x-5)
then
The Rule of the translation is
(x,y) -----> (x+5,y)
That means ----> The translation is 5 units at right
so
(−1,−3) ----> (-1+5,-3)
(−1,−3) ----> (4,-3)
It's (5,2) , I took it already so here you go
