I believe you set them equal to each other.
2x+4=5x-9
x=4.3
2(4.3)+4=12.6
I think the answer is 12.6
Step-by-step explanation:
the eqn is 3x-2y+10=0
slope m=-3/-2=3/2 (m=(-xcoeff/ycoeff)
eqn is
y-y1=m(x-x1)
y+5=3/2(x-2)
2y+10=3x-6
3x-2y-16=0
You can multiply 2/3 by 2/2 to get 4/6. This means that x=4!!!
Hope this helps :)
20 hours = 5 gallon
-------------------------------------------
Find 1 hour :
-------------------------------------------
1 hour = 5 ÷ 20
1 hour = 0.25
-------------------------------------------
Find 48 hours :
-------------------------------------------
1 hour = 0.25
48 hours = 0.25 x 48
48 hours = 12 gallons
--------------------------------------------------------------------------------------
Answer: 12 gallons of water will leak in 48 hours.

A function is differentiable if you can find the derivative at every point in its domain. In the case of f(x) = |x+2|, the function wouldn't be considered differentiable unless you specified a certain sub-interval such as (5,9) that doesn't include x = -2. Without clarifying the interval, the entire function overall is not differentiable even if there's only one point at issue here (because again we look at the entire domain). Though to be fair, you could easily say "the function f(x) = |x+2| is differentiable everywhere but x = -2" and would be correct. So it just depends on your wording really.
