Answer:
40 years
Step-by-step explanation:
Hulian and Thomas together is 65 years
let us suppose hulian is X
now, so Thomas is x+15
so x+x+15=65
so 2x = 65-15
2x=50
x=25
Hulian is 25
and Thomas is 25+15=40

Answer:
2.5
Step-by-step explanation:
The graph shows the curve extends downward to y = 2.5 in several places.
2.5 is the minimum value
_____
<em>Additional comment</em>
In this case, we assume the arrows at the ends of the curve mean the curve continues in the same fashion (same period and amplitude) as the part shown. For some graphs, arrows at the ends of the curve mean the graph extends to infinity in that direction.
Answer:
the length is 11
the width is 5
Step-by-step explanation:
5 times is 15 and 11 is 4 less than 15 :)
Plug in x = 12 and y = -5 into the given equation:-
3(12) - 3(-5) = 36 + 15 = 51 Not 21
So (12,-5) is not a solution.
