Answer:
B
Step-by-step explanation:
you need to find the absolute value
In the whole wide world of math, there is only one number that equals 19.
That number is . . . . . . . . . . wait for it . . . . . . . . . . 19 .
Let's make an equation to show how to get how many people were in 105,000.
But, with a decrease, you have to decrease it from 100.
100-12.5
87.5
So it will be 87.5 of what it was previously. Now let's get to the equation.
.875x=105,000
Let's divide each side.
105,000÷.875
120,000
Let's check if this was a 12.5% decrease.
120,000×0.125
15,000
120,000-15,000
105,000
So the population of 2010 was 120,000 people.
y = - x -
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 6, 1 ) and (x₂, y₂ ) = (2, - 5 )
m = = = -
the partial equation is
y = - x + c
to find c substitute either of the 2 given points into the partial equation
using (- 6, 1 ), then
1 = + c ⇒ c = 1 - = -
y = - x - ← equation of line
