Step-by-step explanation:

If F(x) = 2x+6, g(x) = 3² findf(g (-3))

Solution

f(g (-3)) = 2x+6(3²(-3)) = 2x+6(3×3(-3))

= 2x+6(-27) = 54x-162 = 54x = 162

54/54x = 162/54

x = 3

Answer:

➩ f(g(-3)) = 24

Step-by-step explanation:

➨ Rearrange/Simplify the equations

F(x)=2x+6\\g(x)=9

➨ Find f(g(-3))

g(-3)=9 ➩ All x-values have same y-values ➩ Constant Function

Substitute g(-3) = 9 in the f(x)

f(g(-3)) = f(9)\\f(9)=2(9)+6\\f(9)=18+6\\f(9)=24\\f(g(-3)) = 24

Thus, the answer ➩ f(g(-3)) = 24

How to solve this question ​
yarga [219]

Answer:

BC = 3.6

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{BC}{DE} = \frac{AC}{AE} , substitute values

\frac{BC}{1.2} = \frac{4.5}{1.5} ( cross- multiply )

1.5 BC = 5.4 ( divide both sides by 1.5 )

BC = 3.6
