Answer:

g(x) = x+2

Step-by-step explanation:

f(x) = x^2 + 1

fg(x) = x^2 + 4x + 5

Find the function g(x) so that when you put it into f(x) you get x^2 +4x + 5

g(x) = x+2

Andre and Diego were each trying to solve 2X +6 equals 3X -8 describe the first step they make to the equation
yulyashka [42]

The first step is: subtracting 6 from both sides

Step-by-step explanation:

Given equation is:

2x+6=3x-8

the given equation is a linear equation in one variable.

The simple rules to solve equations are that any operation performed on one side of the equation is also performed on other side of the equation too.

So for the given equation, in order to isolate the variable x terms on one side first of all they will subtract 6 from both sides

2x+6-6 = 3x-8-6\\2x = 3x-14

Subtracting 3x from both sides

2x-3x = 3x-14-3x\\-x = -14\\x = 14

Hence,

The first step is: subtracting 6 from both sides

Firdavs [7]

Answer:

5 35/72 kilometers

Step-by-step explanation:

The distance around a lake is 6 7/12 kilometers. Evan rode his bike 5/6 of the distance around the lake. What is the distance in kilometers that Evan rode

This is calculated as:

Total distance = 6 7/12 km

Evan rode = 5/6 of the distance

Hence:

The distance Evans rode is

5/6 of 6 7/12

= 5/6 × 79/12

= 395/72

= 5 35/72 km(kilometers)
