Answer:
Step-by-step explanation:
The relationship between the values of the digits in the number 9,999,999 is that, the value of each digit is 10 times of the value of the ...
54 miles
using the formula
speed = 
= 
= 12 mph
continuing at 12 mph then
distance = speed × time = 12 × 4.5 = 54 miles
Answer:
The constant of proportionality is 5/3
Step-by-step explanation:
3 * k = 5
k = 5/3
Check
9 * k = 15
9 * 5/3 = 15
3*5 = 15
15 =15
The constant of proportionality is 5/3
Answer:
C
Step-by-step explanation:
first of all, the correct factorization is
y = (x - 3)(x + 6)
because when we do the multiplication
y = x² + 6x - 3x - 18 = x² + 3x - 18
and then, the factorization tends us also directly the zero points, because y is only 0, when one of the factors is 0.
so, either x-3 or x+6 has to be 0 to make the whole expression 0.
and that is only for x=3 or x=-6
