8m+3v=51

2m+5v =34

multiply the 2nd equation by -4

-8m -20v = -136

add 1 and the modified 2nd equation together

8m+3v=51

-8m -20v = -136

------------------------

-17v = -85

divide by -17

v=5

substitute into 1st equation

8m+3v=51

8m +3(5) = 51

8m +15 = 51

subtract 15 from each side

8m =36

m =4.5

Answer: videos are $5.00

The functio p(x)= x(x-5)(x-2)(x+3) has four zeros. What is the smallest zero.
loris [4]

Answer:

x = 5 or x = 2 or x = 0 or x = -3 thus 0 is the smallest root

Step-by-step explanation:

Solve for x:

x (x - 5) (x - 2) (x + 3) = 0

Split into four equations:

x - 5 = 0 or x - 2 = 0 or x = 0 or x + 3 = 0

Add 5 to both sides:

x = 5 or x - 2 = 0 or x = 0 or x + 3 = 0

Add 2 to both sides:

x = 5 or x = 2 or x = 0 or x + 3 = 0

Subtract 3 from both sides:

Answer: x = 5 or x = 2 or x = 0 or x = -3
