Multiple 2x * 5x =10x^2
Multiple 2x * -1 = -2x
Multiple 6 * 5x = 30x
Multiple 6 * -1 = -6
Add 30x + (-2x) = -28x
10x^2 + 28x -6 is the final answer
When you plot the numbers on a graph or draw a histogram using them, you find the distribution shapes are
Lake A: ∩
Lake B: ∪
Lake C: ∩
Lake D: ∩
Apparently the weights of fish in Lake B have a U-shaped distribution.
Answer:
x=-10
Step-by-step explanation:
15-2(x+5)=25
multiply the 2 by the x and 5 and you get
15-2x-10=25
since the 15 and the negative 10 are on the same side you add them together and get
5 -2x= 25
-5 -5
-2x =20
Then divide the -2/20= -10
0.4% of 100 is .4 whoops i thought it was 0.4 as a decimal :P
Answer: 
Step-by-step explanation:
Two lines are said to be perpendicular if the product of their slope = -1
Given :
to find the slope , we will write it in the form : 
That is
which means that the slope = 
any line that is perpendicular to this line will have slope = -2
using the formula :
, we have
