Answer:
(f - g)(-4) = 17
Step-by-step explanation:
To get (f - g)(x), you need to subtract f(x) with g(x).
f(x) = 2x² + 2
g(x) = -3x + 5
(f - g)(x) = (2x² + 2) - (-3x + 5)
(f - g)(x) = 2x² + 2 + 3x - 5
(f - g)(x) = 2x² + 3x - 3
Now, plug in -4 to find (f - g)(-4).
(f - g)(x) = 2x² + 3x - 3
(f - g)(-4) = 2(-4)² + 3(-4) - 3
(f - g)(-4) = 2(16) + 3(-4) - 3
(f - g)(4) = 32 - 12 - 3
(f - g)(-4) = 17
The value of TY is 14
Given that CD is the perpendicular bisector of XY and ST and CY = 16
We need to find the value of TY
Here M is the midpoint of ST and D is the midpoint of XY
As shown in the diagram we can say that
CT = CS =12
We can also say that ST║XY
So , ∠CST = ∠CSY
∠CTS = ∠CYX
ΔSCT = ΔXCY
SX = CS - CX
= CY - CX
We can say that MT = SM = 5
DY = DX = 7
TY = SX = 4
CY = CX = 16
ST = SM + MT
ST= 5+5
∴ ST= 10
XY = XD +DY
XY = 7+7
∴ XY = 14
Hence the value of XY is 14
