Answer:
∠XVW = 36°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠WXY is an external angle to the triangle and
∠XVW and ∠VWX are the 2 opposite interior angles, thus
6x - 19 = x + 17 + 3x + 2, that is
6x - 19 = 4x + 19 ( subtract 4x from both sides )
2x - 19 = 19 ( add 19 to both sides )
2x = 38 ( divide both sides by 2 )
x = 19
Hence
∠XVW = x + 17 = 19 + 17 = 36°
plugging x=-2 in the given equation we get
=12/3²
=12/9
=4/3
so answer is 4/3
Answer: f-1(x) = 9x + 18.
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 2 ( add 2 to both sides )
y + 2 = x
Multiply through by 9 to clear the fraction
9y + 18 = x
Change y back into terms of x
(x) = 9x + 18
1 gallon = 16 cups, then 2 gallons= 32 cups
