y = 3(-x - 2)
Any horizontal transformations or reflections you make to y = x must be within the parentheses.
Answer:
x=-1
Step-by-step explanation:
4x-16=-20
Get x to one side by subtracting it.
-16=-20-4x
Add the 20 on both sides.
-16+20=-4x
Simplify
4=-4x
4/-4=-4x/-4
-1=x
x=-1
Answer:
Step-by-step explanation:
Given:
Width of average grain of salt is, 
Width of Rhinovirus is, 
Now, expressing each width in scientific notation form, we get:
Now, in order to get how many times 'W' is wider than 'w', we divide the two widths. This gives,
Therefore, the grain of salt is wider than Rhinovirus.
Answer:
B
Step-by-step explanation:
If you arrange a statistics in order from least to greatest, the middle number is the median.
If there is even number of numbers in a list, let it be n numbers, then we take the average of n/2th and n/2 + 1 th terms.
Here, all of them have 6 numbers, so 6/2 = 3 and 4th, we take average of 3rd and 4th number to find the median.
Since they are arrange in order we check each:
Jon = average of 6 and 7, (6+7)/2 = 6.5
Leroy = average of 6 and 8, (6+8)/2 = 7
Simon = average of 5 and 6, (5+6)/2 = 5.5
Leroy's median is the greatest (7).
A point doesn't have slope. Once you have TWO points, then the line between them has a slope.
The slope is (how far the line rises from one point to the other) divided by (the level distance between them).
