Which are the solutions of the equation 4x^2-7x=3x+24

vfiekz [6]

Answer:

x=4

Step-by-step explanation:

Because 4 to the power of 2 is 16.

Then, you subtract: 16x - 7x

Then, what you are going to see is 9x=3x+24

So, you subtract: 9x - 3x

Finally, you will have 6x=24... You divide: 24/6 and the answer is x=4.

Answer:

f[g(2)] = 50

Step-by-step explanation:

<u>Given functions:</u>

$f(x)=2(x+1)^2$

$g(x)=3x-2$

We are asked to determine f[g(2)], which is known as a composite function. When solving composite functions, you always work inside out.

Step 1: Find the value of g(2) by substituting 2 for x in function g(x).

$\implies g(2)=3(2)-2$

$\\\implies g(2)=6-2\Rightarrow g(2)=\boxed{4}$

Step 2: Substitute the found value into the composite function.

$\\\implies f[g(2)]= 2(4+1)^2$

$\implies f[g(2)] = 2(5)^2 \Rightarrow 2(25) \Rightarrow \boxed{50}$

Hence, the value of the composite function f[g(2)] is 50.
