60/12=5. We use the number 60 because60 minutes per hour, 8x5=40. 40mph
To find a perpendicular line, you need to find the negative reciprocal of the slope.
-2/5 flips into -5/2
Since -2/5 is negative, -5/2 turns positive, so 5/2.
Therefore, the slope of a line perpendicular to Y = -2/5x + 4/5 is 5/2
Answer:
The range of the data is the difference between the largest and smallest value. In this case, the largest value is 8 and the smallest value is 1.
Hence, the range is
.

The mode is the value that appears in a data set the most. When you arrange them in ascending order:

You can count that the value "6" appears five times, which is the most in this set.
Hence, the mode is 6.
Answer:
x = -10
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
8x - 2(x + 1) = 7x + 8
Step 2: Distribute
8x - 2x - 2 = 7x + 8
Step 3: Combine like terms
6x - 2 = 7x + 8
Step 4: Subtract 6x on both sides
-2 = x + 8
Step 5: Subtract 8 on both sides
-10 = x
Step 6: Rewrite
x = -10
