Answer:
Dave is 6 years 4months 16 days 12 hours old
Step-by-step explanation:
Age of Dave Dog = 10year( 1 decade)+ 9 months+3 days
Age of Dave=
= 6 years 4months 16 days 12 hours
2x + 3y = 1200
3y = -2x + 1200
y = -2/3x + 400......slope = -2/3....y int = (0,400)...x int = (600,0)
start at (0,400)...and since ur slope is -2/3, go down 2 spaces, and to the right 3 spaces...plot this point...then go down 2, and to the right 3...plot this point....keep doing this and u should cross the x axis at (600,0).
square root n+5-square root n-10=1
add sqrt(n-10) on both sides
To remove square root we take square on both sides
Subtract n and add 9 on both sides
Now we divide both sides by 2
Take square on both sides
+-49= n - 10
49 = n-10 and -49 = n - 10
Add 10 on both sides
n= 59 and n = -39
Now we verify both solutions
When n = -39 we will get negative under the square root . that is complex so we ignore n=-39
n = 59 is our solution
