Answer:
10 miles
Step-by-step explanation:
Setting up an equation where the variable 'x' = the number of miles, we can find the total mileage for the passenger's trip:
$6 = $0.75x + $2.25
$6 = the total amount of the trip
$0.75 = the cost for each mile after the initial 5 miles
$2.25 = the flat fee for the first 5 miles
Solve for 'x', subtract $2.25 from both sides: 6 - 2.25 = 0.75x + 2.25 - 2.25 or 3.75 = 0.75x
Divide by 0.75: 3.75/0.75 = 0.75x/0.75 or x = 5 miles
Since the passenger was charged in additional 5 miles, then the total mileage is 10 miles.
Answer:
Step-by-step explanation:
The pair of segments on the right tells you the ratio of the segment length above the horizontal line to that below the horizontal line is ...
18 : 6 = 3 : 1
Then x = 3 times 5 = 15.
12 is 3 times y, so y = 4.
Answer:
The answer is A
Step-by-step explanation:
We can tell by finding out what each points coordinates are.
Its quite hard to describe how to do this on a phond yet you use the rule of
X coordinate first, then Y coordinate.
so (-5,5). -5 is the x coordinate
and 5 is the y coordinate.
Graphs can be quite difficult but for now, just remember x is across and y is up.
Good luck with future questions!
Answer:
y= -11/144(x-8)^2+6
Step-by-step explanation:
This equation can be represented in vertex form, which is:
y=a(x-h)^2+k
If we plug in 8 as h and 6 as k we get the following equation:
y=a(x-8)^2+6
Now we have to plug in x and y. We can use the other point (-4,-5) and plug it into the equation and get:
-5=a(-4-8)^2+6
Once we solve this we get a= -11/144
Now we have to plug in -11/144 into the original equation to get
y = -11/144 (x-8)^2 + 6
