Answer:

ok the slope is -1/2

the points I used where (-6,-1) and (-2,-3)

the intercept of y is -4

the equation is 2y +x+8=0

Step-by-step explanation:

using the formula y2- y1 = m

X2-X1

where m is the gradient, the slope is found

the original equation is y=-1/2x-4

and so if x is zero ( to get the y intercept)

y=-4

using the formula y - y1= m( x -x1 )

, the equation is determined

Answer:

$y(x)=-0.028x+14.6$

Step-by-step explanation:

Birth Rate in 1994 = 14.6 births per thousand population.

Birth Rate in 2004 = 14.32 births per thousand population.

A linear equation is of the form: y=mx+c

Where:

x=years after 1994
y=the birth rate
m=Yearly Birth Rate

First, we determine the birth rate per year

$m=\dfrac{14.32-14.6}{10-0}\\=\dfrac{-0.28}{10}\\m=-0.028$

Therefore, a linear equation that relates y in terms of x is of the form:

$y(x)=-0.028x+c$

When x=0, y=14.6

14.6=-0.028(0)+c

c=14.6

Therefore, the linear equation that relates y in terms of x is:

$y(x)=-0.028x+14.6$

-4|x-11|=-16 solve for x in the equation

BigorU [14]

Answer:

x = 7 and 15

Step-by-step explanation:

Divide both sides by -4...

| x - 11 | = 4

because

| -4 | = 4 and

| 4 | = 4

x - 11 = -4 and x - 11 = 4

solve for x in both equations.

x = 7 and x = 15
