Answer:
0 ≤ x ≤ 18
Step-by-step explanation:
Let 'x' be the number of youth tickets purchased at the zoo and 'y' be the number of adult tickets purchased at the zoo.
At a zoo, youth tickets cost $5 and adult tickets cost $9. A group spent a total of $90 on tickets. We can write as
5x + 9y = 90
to find x we divide both side by 5
x = (90-9y)/5 => 90/5 - 9y/5
x = 18 - 9y/5
The domain of the relationship is the possible set of values of x and y that satisfies the equation. The domain of this relationship is
0 ≤ x ≤ 18
At x = 0, it means only adult tickets were purchased.
At x = 18, it means only youth tickets were purchased.
Answer:
Step-by-step explanation:
9.)
z + 3 > 2/3
z > -7/3
You want an unshaded dot on the point -7/3 going towards the right.
10.)
1/2 ≤ c - 3/4
5/4 ≤ c
You want a shaded dot on the point 5/4 going towards the left.
The answer uses NMF for formatting, which you can find out about in my profile if needed:
the equation is this:
time = {total paid - 35}/{15}
Put in what we know:
time = {95 - 35}/{15}
time = {60}/{15}
time = 4 hours
Can you please add a picture of the problem or type all the measurements and information?
