Answer:
x=4
Step-by-step explanation:
1. isolate the variable by subtracting 7 on both sides: 4x=23-7
2. simplify: 4x=16
3. divide both sides by 4: x=16/4
4. simplify: x=4
Oz(384n/16oz)=24n
So there are 24 nails per ounce in the jar.
Answer:
8
Step-by-step explanation:
let the numbers be x,x+1,x+2
x+x+1+x+2=27
3x+3=27
3x=27-3=24
x=24/3=8
The y-intercept for f(x)=|x|-5 is (-5). Just look at the function as slope-intercept form and find the number that is not being multiplied by x. That number will usually be your y-intercept.
Answer:
relative minimum
Step-by-step explanation:
From f^''(x) = 12x we can take the integration to find out what f'(x) is:
Furthermore, we can substitute x = 1 for f''(x) to find out whether it's positive or negative
f''(1) = 12*1 = 12 > 0
So if x=1 is a critical point of f'(x) and f''(x=1) > 0 then that point is a relative minimum point
