Answer:
X2 = (-2, 1), W2 = (-4, 1), Y2 = (4, -2), Z2 = (-3, 2)
Step-by-step explanation:
First, flip across the y-axis:
Coordinates: X1 = (2, -1), W1 = (4, -1), Y1 = (2, -4), and Z1 = (3, -2)
Then, rotate 180 degrees counterclockwise:
Coordinates: See above
Answer:
The answer is:
30 minutes.
Step-by-step explanation:
We are given the following information:
at 160 m/min, tool life = 5 min.
at 120 m/min, tool life = 17 min.
This means that as the speed reduced from 160 m/min to 120 m/min, the tool life increased from 5 min. to 17 min, hence the difference between the changes are:
speed = 160 - 120 = 40 m/min
tool life = 17 - 5 = 12 min.
Therefore, it can be concluded that a change of speed of 40 m/min, increases the tool life by 12 min.
40 m/min = 12 min
∴ 1 m/min = 12/40 min.
∴ 100 m/min = 12/40 × 100 = 0.3 × 100 =30 min.
Answer:
Terms: 4x, -
Coefficients: 4, 
Step-by-step explanation:
The terms of an expression are the numbers and variables that are being added. In this expression 4x is being added to -. This means that they must be the terms. The coefficients are the constants that come before a variable. A variable is an unknown number represented by a letter, in this case, x. So the coefficients are 4 and because both these numbers are being multiplied by a variable.
the answer is A because you would do 4x1+2 and then you would do 4x2+2 and so on
