Given:
The function is
To find:
The value of f(-1).
Solution:
We have,
Putting x=-1, we get
Therefore, the value of f(-1) is -12.
Answer:
There is 7/15 left in the bag
Step-by-step explanation:
So, you need to find a common denominator between 3 and 5 which is 15
multiply the numerator and the denominator by 3 in 1/5. Then, multiply the numerator and the denominator by 5 in 1/3.
1/3*5=5/15
1/5*3=3/15
Add them together.
5/15+3/15=8/15
Lastly, subtract 15/15 by 8/15
15/15-8/15=7/15
2x - 3y = 8
Subtract '2x' to both sides:
-3y = -2x + 8
Divide -3 to both sides:
y = 2/3x + 8/3
or
y = 2/3x + 2 2/3
Answer:
A'(-3, 0) B'(0, -1) C'(1, -4)D'(-3, -5)
Step-by-step explanation:
You find each dot and move 2 squares left and 4 squares down.
You now find the first number by finding which x-values it is above/below on the x-axis (horizontal bold line).
Then for the second by finding which y-values it is beside on the y-axis (vertical bold line).
Rounding 122.14 to the nearest 10 and 6.2 to the nearest whole number gets us the values 120 and 6. Using these estimates for our division gives us the rough result 120 ÷ 6 = 20. 6.2 is a larger number than 6, so division by 6.2 will lower our result, but 122.14 is also bigger than 120, so this increase will raise our result a little as well. The net effect will make the actual quotient come out slightly lower than our estimate of 20, so 19.7 is a perfectly reasonable value.
