Answer:
<u>D) (f o g)(x) = 10x² - 60x + 93</u>
Step-by-step explanation:
f(x) = 10x² + 3
g(x) = x - 3
⇒ (f o g)(x)
⇒ f(x - 3)
⇒ f(x - 3) = 10(x - 3)² + 3
⇒ f(x - 3) = 10(x² - 6x + 9) + 3
⇒ f(x - 3) = 10x² - 60x + 90 + 3
⇒ <u>(f o g)(x) = 10x² - 60x + 93</u>

(25)-(3)
Step-by-step explanation:
The area of real backyard is 72 square meters.
Step-by-step explanation:
Given,
Length of rectangular backyard = 8 cm
Width of rectangular backyard = 4 cm
According to scale;
2 cm = 3 m
1 cm = 
Real length of backyard = 8*1.5 = 12 m
Real width of backyard = 4*1.5 = 6 m
Real area of backyard = Length * Width
Real area of backyard = 12*6 = 72m²
The area of real backyard is 72 square meters.

Answer:
Step-by-step explanation:
dy/dx= -(2x+3y+1)/(3x-2y+1)
Let x= X+p. and y = Y+q. then dy/dx = dy/dX.
dy/dX= -(2X+2p+3Y+3q+1)/(3X+3p-2Y-2q+1) =
dy/dX = -{2X+3Y+(2p+3q+1)}/{3X-2Y+(3p-2q+1)}
Now 2p+3q+1=0……………..(1)
3p-2q +1=0…………………………(2)
p/(3+2)=q/(3–2)=1/(-4–9)
