If f(x) = 3x – 1 and g(x) = x^2 + 4, find the (gºf)(x).

mezya [45]

Answer: 9x²-6x+5

Step-by-step explanation:

To find (gοf)(x), you want to plug f(x) into g(x). It is the same as g(f(x)).

g(f(x))=(3x-1)²+4 [distribute by FOIL]

g(f(x))=9x²-6x+1+4 [combine like terms]

g(f(x))=9x²-6x+5

Now, we know that (gοf)(x)=9x²-6x+5.

On a partly cloudy day, Derek decides to walk back from work. When it is sunny, he walks at a speed of s miles/hr (s is an integ

Setler [38]

Answer: $\frac{1}{7}$

Step-by-step explanation:

Given

sunny day speed= s mph

Rainy day speed=s+1 mph

Derek average speed =2.8 miles/hr

s<2.8<s+1

so on sunny day speed must be 2 mph

and on rainy day speed must be 3 mph

$v_{avg}=\frac{distance}{time\ taken}$

Let x be the distance traveled in sunny and y be the distance traveled in rainy weather

$2.8=\frac{x+y}{\frac}{x}{2}+\frac{y}{3}}$

Let $\frac{x}{y}=z$

$2.8=\frac{z+1}{\frac{z}{2}+\frac{1}{3}}$

$z=\frac{1}{6}$

Fraction of distance traveled on sunny weather

$\frac{x}{x+y}=\frac{z}{z+1}=\frac{1}{7}$

Sati [7]

<u>ANSWER: </u>

Scott has 6000 points in his fantasy baseball league.

<u>SOLUTION: </u>

Given, Donal currently has 7,200 points in his fantasy baseball league.

It is 20% more points than Scott points.

We need to know how many points does scott have?

Let the points with scott be x.

Then, according to give information

Donal points = scott points + 20% of scott points

$\begin{array}{l}{7200=x+20 \% \times x} \\\\ {7200=x+\frac{20}{100} \times x} \\\\ {7200=x+\frac{1}{5} \times x} \\\\ {7200=x+\frac{x}{5}}\end{array}$

By multiplying with 5 on both sides, we get

$\begin{array}{l}{7200 \times 5=5 \times x+x} \\\\ {36000=5 x+x} \\\\ {6 x=36000} \\\\{x=\frac{36000}{6}} \\\\ {x=6000}\end{array}$

Hence, scott has 6000 points in his fantasy baseball league.

yKpoI14uk [10]

Answer:

The coefficients are

11,-4 and 0.

Step-by-step explanation:

We are given two algebraic expressions. We are subtracting the second from the first.

First one is:

(4x²y3 + 2xy2 - 2y)

Second expression is:

(-7x?y3 + 6xy2 – 2y)

The given expression:

(4x²y3 + 2xy2 - 2y) - (-7x?y3 + 6xy2 – 2y)

The coefficients are

11,-4 and 0.
