Answer:
D) 1541
Step-by-step explanation:
I like to answer it w without deriving the formula of f(g(x)). So, we go this way, you firstly have to find g(7) which will be equal to 3 * 7 - 5 = 16.
And then you find f(16) = 6*16*16+5 = 1541. That's all.

Answer:
b = -36
Step-by-step explanation:
Start by distributing both th 5 and the negative 1 into their corresponding parentheses.
((5*2b)-(5*3)) > (10b - 15)
((-1*11b)+(-1*1)) > (-11b - 1)
so you have:
10b - 15 - 11b - 1 = 20
Next you would Combine like terms to get:
-b - 16 = 20
Add the 16 to both sides
-b = 36
and divide each side by -1
b = - 36
hope this helps
The two ys must be the same. Equate the two right hand sides.
-x + 10 = x + 2 add x to both sides.
10 = x + x + 2
10 = 2x + 2 Subtract 2 from both sides.
8 = 2x Divide by 2
x = 8/2
x = 4
Now solve for y
y = x + 2
y = 4 + 2
y = 6
Use the other equation to check it.
y = - x + 10
y = -4 + 10
y = 6
Step-by-step explanation:
72/64=x/8
=> x = (72×8)/64
=> x = 9.
hope this helps you.
