Answer:
C
Step-by-step explanation:
x + 11 = 24
x = 13
Option B Inverse Variation because xy=240 is correct.
Step-by-step explanation:
if Alejandro rides 10 mph it takes him 24 minutes.
if Alejandro rides 12 mph it takes him 20 minutes.
Making table for given data set.
Considering miles as y and time as x
Miles(y) Time (x)
10 mph 24 minutes
12 mph 20 minutes
If the miles are increasing the time taken is less, so the variation is inverse.
The formula used to find inverse variation is:
Where y is miles and x is time, and k is constant
Putting y = 10 and x = 24
So, the value of k constant is 240.
For any value of x and y the value of k will be 240
Hence Option B Inverse Variation because xy=240 is correct.

Answer:
Elimination
Step-by-step explanation:
The following system of equations can be easily solved by elimination as we can simply eliminate x-term.
Substitution will take a lot of time because you need to move to make either x-term or y-term as the subject then substitute in.
Graphing Method — You need to find the intercepts of both equations. You also have to convert into slope-intercept form which takes a lot of time.
Since the parabola is opening upwards it has to be positive. The equation you said it might be is wrong b/c then the parabola would open downwards. the answer is y=x^2+3. And you can use this website for graphing it will help. it helps me.
