To figure out this question, look for the first number where both 25 and 9 are a factor of.
25*1 is 25 which isn't a factor of 9, so it won't be 25.
25*2 is 50, which isn't a factor of 9.
75 is not a factor of 9. (you know because you don't get a whole number when you divide 75 into 9.)
100 is not a factor of 9, nor is 125, 150, 175, or 200.
However, 225 is a factor of both 25 and 9. This makes sense because 25*9 is 225.
This means that the first package with both will be the 225th package.
Answer:
X-intercepts: (-3,0) and (5,0)
Y-intercept: (0,-15)
Step-by-step explanation:
x^2 - 2x - 15
(x + 3) (x -5)
x +3 = 0
x = -3. (-3, 0)
x - 5 = 0
x = 5. (5, 0)
Answer:
<u>The taxi ride was for 23 miles.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Function of total cost (C)ₙ = 10 + 1.50n
n = Miles of the taxi ride
C = Cost in dollars of the taxi ride
Total cost = $ 44.50
2. For how many miles was the taxi ride?
Let's replace the cost of the taxi ride in the function given for solving for n, this way:
10 + 1.50n = 44.50
1.50n = 44.50 -10
1.50n = 34.50
n = 34.50/1.50
n = 23
<u>The taxi ride was for 23 miles.</u>
Answer:
the correct for this question is be over the y-axis (x,y)=(-x,y)
She traveled 11 floors.
Explanation:
Wanda stepped onto an elevator at the 8th floor after that comes the 7th floor, 6th floor, 5th floor, 4th floor, 3rd floor, 2nd floor, 1st floor and then ground floor . Hence from 8th floor to ground floor Wanda traveled 8 floors. After ground floor she travels 3 floors more that is -1,-2,-3 . Hence here she travels 3 floors underground. Therefore, the total number of floors traveled by Wanda are 8 floors+3 floors= 11 floors.
