Answer:
360 miles
Step-by-step explanation:
When the second car catches up with the first car they will have travelled the same distance which we call x miles.
Speed = distance / time
For first car 60 = x / t where t = time taken
giving x = 60t
for second car 90 = x / (t - 2)
giving x = 90t - 180
So equating these 2 equations
60t = 90t - 180
30t = 180
t = 6 hours
So x the distance = 60t = 360 miles answer
Answer:
you need to find the vertex, y-intercept, x-intercept, etc in order to create the equation.
Step-by-step explanation:
standard form for quadratic equations should look like this:
f(x)= ax^2+bx+c
(The graph is really blurry, try posting just the graph so I can see it closer if you still need help setting up the equation.)
Answer:
A is a correct answer i think
Answer:y=5
Step-by-step explanation:
5(y+1)=30
Divide both sides by 5
5(y+1)/5=30/5
We get y+1=6
Subtract 1 from both sides
y+1-1=6-1
We get y=5
The data is skewed to the right so the mean will be higher than the median. The median would be a better picture of the data.
