Answer:
my answer is negative 14/3.
Step-by-step explanation:
choice A hope that helps you if I'm wrong please tell me the right answer right away I can try another method.
First you gotta look for the value of the 25% in the 40$ So it will be
25&=0.25
0.25x40=10
Now all you gotta do it’s
40-10=30
You subtract becaus le they ask you to find the price before it was increased so that why you gotta subrtract it
Answer:
Option A is correct answer.
Step-by-step explanation
If the given function is given as
f(x) =
then vertex is (h,k) and Its domain is set of all real numbers
and range is given to be y ≥k for a>0
So here in the question the equation is given as
on comparing the equation with given standard equation
we get a=3 which is greater than zero
h =1 and k=2
therefore vertex is (1,2) ,Domain is set of all real number
and range is y≥2
That is option A is correct!
Answer:my brother said 3.
Step-by-step explanation:
Let x = miles traveled by car
Let y = miles traveled by truck.
Because the total distance is 305 miles,
x + y = 305 (1)
Let t = hours of travel by truck. Because the truck speed is 55 mph,
55*t = y
or
t = y/55 (2)
The car has an hour head start, therefore it travels for (t + 1) hours.
Because the car travels at 65 mph,
65*(t + 1) = x
Substitute (2) to obtain
65*(y/55 + 1) = x
or
1.1818y + 65 = x (3)
From (1), obtain
1.1818y + 65 = 305 - y
2.1818y = 240
y = 110
x = 305 - y = 195
From (2),
t = 110/55 = 2 hours
The two vehicles pass each other at 2:00 pm + 2 hours = 4:00 pm
Answer: 4:00 pm
