Answer:
Yes.
Step-by-step explanation:
The relation would be 3 = k*9 as there is a direct proportional relationship.
So k = 3/9 = 1/3 and we can write the relation as d = 1/3 t where d=distance and t = time.
So if we double the time t we have:-
d = 1/3 * 18
= 6 kilometers.
So the distance is doubled.
Answer:
This true because why ?
Step-by-step explanation:
Answer:
The width is 7 inches, the length is 15 inches
Step-by-step explanation:
If the width is x inches, then the length is 2x+1 inches. Since the perimeter of a rectangle is 2 times the width plus 2 times the length, the perimeter will be 2x+2(2x+1), which simplifies to 6x+2. Since the perimeter is 44 inches, we get the equation 6x+2=44, which makes x=7. So, the width is 7 and the length is 15.
(-2,1) i think that’s the answer
Answer:
(3,7) and (-3,-5)
Step-by-step explanation:
To solve the system of equations, graph both functions. The (x,y) point(s) where the functions intersect is the solution(s).
