Answer:
x = 10
Step-by-step explanation:
You know z = x+4, so ...
3z -x/2 = 37 . . . . . . . . the given relation
3(x +4) -x/2 = 37 . . . . substituting for z
5/2x +12 = 37 . . . . . . .eliminate parentheses and simplify
5/2x = 25 . . . . . . . . . . subtract 12
x = 10 . . . . . . . . . . . . . multiply by 2/5
_____
<em>Check</em>
3z = 3·14 = 42
x/2 = 10/2 = 5
42 exceeds 5 by 37 . . . . true
Answer:when x = -11
2×11-19=22-19
=3

The answer is "".
Step-by-step explanation:
Equation of the parabola:
if the value of a= then put the value into the equation:
when depth of water y=5
So, width:
Yes, if the rule is
... output = input + 12
you add 12 to whatever input value you might have. For an input of 6, this is
... output = 6 + 12 = 18
