Same number vertical angles and shape i think
Answer: y = -3x + 1
step-by-step process
find the slope first using (y-y)/(x-x)
(4-(-5))/(-1-2) = 9/(-3)
m = -3
then use one of the points to find the y-intercept by putting it in y=mx+b, substituting m with -3 (aka the slope) as well
4 = -3(-1) + b
4 = 3 + b
4 - 3 = 3 + b - 3
1 = b
therefore, the equation for the line is: y=-3x+1
The <em><u>correct answer</u></em> is:
Explanation:
An exponential function is of the form
, where a is the initial population, b is 1 plus the amount of yearly change, and x is the number of years.
For our problem, a, the initial population, is 1500.
The yearly change is 6.3%; 6.3% = 6.3/100 = 0.063. Since it is decreasing, this is negative; 1+(-0.063) = 0.937.
We use t as the number of years.
This gives us
9514 1404 393
Answer:
4
Step-by-step explanation:
210 = 2·3·5·7
There are 4 distinct prime factors.
Step-by-step explanation:
4/m=16
4/m=16/1
16m=4
divide both sides by 16
therefore, m is equal to 0.25
