Answer:

x = $\frac{15}{2}$ , x = 1

Step-by-step explanation:

(a)

$\frac{4x-1}{2}$ = x + 7 ( multiply both sides by 2 to clear the fraction )

4x - 1 = 2x + 14 ( subtract 2x from both sides )

2x - 1 = 14 ( add 1 to both sides )

2x = 15 ( divide both sides by 2 )

x = $\frac{15}{2}$

(b)

3x + 2 = $\frac{2x+13}{3}$ ( multiply both sides by 3 to clear the fraction )

9x + 6 = 2x + 13 ( subtract 2x from both sides )

7x + 6 = 13 ( subtract 6 from both sides )

7x = 7 ( divide both sides by 7 )

x = 1

In 1994, the moose population in a park was measured to be 3000. By 1998, the population was measured

Answer:

P(t) = 100t +2600

4100 in 2005

Step-by-step explanation:

You are given two points for (year, population) = (t, p):

(4, 3000), (8, 3400)

It is useful to use the two-point form of the equation for a line.

p = (p2 -p1)/(t2 -t1)(t -t1) +p1

p = (3400 -3000)/(8 -4)(t -4) +3000

p = 400/4(t -4) +3000

p = 100t +2600

P(t) = 100t +2600 . . . . written in functional form

In 2005, the population is predicted to be ...

P(15) = 100×15 +2600 = 4100

-4x-3y-9=0
|| m1 = - ( - 4)/-3= - 4/3
_|_ m2 = -1/m1= 3/4

2x+4y-3=0
|| m1= -2/4= -1/2
_|_ m2= 2

12x-y-17=0
|| m1= -12/-1=12
_|_ m2 = -1/12

x-y=0
|| m1= -1/-1=1
_|_ m2= -1

8x - 3y - 2=0
|| m1= -8/-3= 8/3
_|_ m2 = -3/8

-2x + y - 5=0
|| m1= -(-2)/1=2
_|_ m2= -1/2
