First, the factor pairs for 18 are:
1, 18
2, 9
3, 6
Since the middle term is -3, the two factors must be 3 apart. The only pair that is 3 values apart is 3, 6.
Since the middle value is negative, the larger number is negative. This means that the 6 is negative.
z = -6
z = 3
Set each equal to 0;
z = -6
z + 6 = 0
z = 3
z - 3 =0
So your factors are (z+6) and (z-3), or answer B.
150mi/3hrs = 50mph
400/50 = 8 hours
Check:
8hours * 50mi = 400 miles traveled
Answer:
{-1,0,1}
Step-by-step explanation:
The domain of a function is the set of all input values. The input values are the first coordinate in any coordinate pair (x,y).
So the domain here is {-1, 0, 1}.
Okay what’s the rest of the question ?
Answer: 3+7+9=19.....7/19=0.368 percent. Move the decimal two places to the right and round up for 37%
Step-by-step explanation:
Add all the colors together to get a TOTAL amount of ALL marbles.
The total amount for this problem is 19 (3+7+9=19)
The blue amount of marbles is given as 7.
Divide the blue amount (7) by the total amount (19) for the specific percentage for that color.
