Answer:
2 sqrt(2x-1)
Step-by-step explanation:
f(x) = sqrt( x+9)
g(x) = 8x-13
f(g(x))
place the function g(x) in for x in f(x)
f(g(x)) = sqrt(8x-13+9)
Combine like terms
f(g(x)) = sqrt(8x-4)
Factor out 4
f(g(x)) = sqrt(4*(2x-1)
2 sqrt(2x-1)
Answer:
-81
Step-by-step explanation:
replace the numbers you were given in a or b.
so
6(-12) -1(-1 – 2 – 6(2)) + 4(-1)(2(2) -1) -12
The area of the triangle is 270 centimeters. The way that I found that out is the equation 30x18/2
Hi There
To find the distance, you have to make them proportional to each other.
1 cent. / 30 kilo. = 7.5 cent. / x
Then you cross multiply.
30 x 7.5 = x
225 = x
The distance between the two cities is 225 kilometers.
Hope that helps:)
