<h2>Evaluating Composite Functions</h2><h3>Answer:</h3>

w(f(m(2))) = 593

<h3>Step-by-step explanation:</h3>

We can write how w(f(m(x))) will be defined but that's too much work and it's only useful when we are evaluating w(f(m(x))) with many inputs.

First let's solve for m(2) first. As you read through this answer, you'll get the idea of what I'm doing.

Given:

m(x) = -4x +1

Solving for m(2):

m(2) = -4(2) +1 \\ m(2) = -8 +1 \\ m(2) = -7

Now we can solve for f(m(2)), since m(2) = -7, f(m(2)) = f(-7).

Given:

f(x)=3x-1

Solving for f(-7):

f(-7)=3(-7)-1 \\ f(-7) = -21 -1 \\ f(-7) = -22

Now we are can solve for w(-22). By now you should get the idea why w(f(m(2))) = w(-22).

Given:

w(x) = x^2 -5x -1

Solving for w(-22):

w(-22) = (-22)^2 -5(-22) -1 \\ w(-22) = 484 -5(-22) -1 \\ w(-22) = 484 +110 -1 \\ w(-22) = 593

Write the equation of a line parallel to the line y = 2x that passes through -2,-1
maksim [4K]

Answer:

y = 2x + 3

Step-by-step explanation:

A line parallel to y = 2x has exactly the same slope but a different y-intercept, b.

Start with y = mx + b, and replace m with 2, y with -1 and x with -2:

-1 = 2(-2) + b, or

-1 = -4 + b.

Then b = 3, and the desired equation is y = 2x + 3

Two thirds the sum of 30 and a number is 26 write this statement out as an equation and solve
zloy xaker [14]

Answer:s

Step-by-step explanation:

Let the number be x

2/3(30+x) = 26

2(30+x) = 26(3)

60 + 2x = 78

2x = 78 - 60

2x = 18

x = 18/2

x = 9

Two students, Ann and Max, factored the trinomial `3x^2 -24x-27`. Ann factored it as 3(x+1)(x−9) and Max factored it as (3x+3)(x
Aloiza [94]
Let's start studying case by case:
 Ann:
 3x ^ 2 -24x-27
 3 (x ^ 2 -8x-9)
 3 (x + 1) (x-9)
 Note:
 (1) * (- 9) = - 9
 (1) + (- 9) = - 8
 check:
 3 (x ^ 2-9x + x-9)
 3 (x ^ 2-8x-9)
 3x ^ 2-24x-27
 She did it correctly.
 
 Max
 3x ^ 2 -24x-27
 (3x + 3) (x-9)
 note: 
 (3) * (- 9) = - 27
 (3) + (- 9) = - 6 (incorrect: the result must be -24)
