The correct second step in solving the equation 8 - 3x = -7 is make 'x' the subject of formula

<h3>What are algebraic expressions?</h3>

Algebraic expressions are defined as mathematical expressions made up of terms, constants, factors, coefficients and variables,

They are comprising of arithmetic operations such as;

Division
Bracket,
Multiplication
Subtraction
Parenthesis
Addition, etc

<h3>What are linear equation?</h3>

A linear equation is defined as an equation having the highest power of the variable to be one.

It is also described as the equation of a line.

Given the equation:

8 - 3x = -7

Take the following steps;

-3x = -7 - 8

Subtract like terms

-3x = -15

Make 'x' the subject of formula by dividing both sides by -3

x = -15/-3

x = 5

Thus, the second step is making 'x' the subject

Samuel takes 5 hours to make a table and a chair. He takes 9 hours to make 3 chairs

nikklg [1K]

Answer:

3 hours

Step-by-step explanation:

t = time to make a table

c = time to make a chair

t + c = 5

t+3c = 9

Subtract the second equation from the first

t+3c = 9

-(t + c = 5)

-----------------------

2c = 4

Divide by 2

2c/2 = 4/2

c =2

2 hours for the chair

t+c = 5

t+2 = 5

t = 5-2

t = 3hours

(A) find F(x) for the indicated values of x, if possible

dem82 [27]

Answer:

A) The indicated values of F(x) for x=-3 and x=5 are $F(-3)=-27$ and $F(5)=125$

B) The domain of f is the set of all real numbers

Step-by-step explanation:

Given that the function F is defined by

$F(x)=x^3$ for x=-3,5

A) To find F(x) for the indicated values of x :

Given $F(x)=x^3$ for x=-3,5

Put x=-3 in the given function

$F(-3)=(-3)^3$

$=(-3)\times (-3)\times (-3)$

$=-27$

Therefore $F(-3)=-27$

Put x=5 in the given function

$F(5)=(5)^3$

$=(5)\times (5)\times (5)$

$=125$

Therefore $F(5)=125$

The indicated values of F(x) for x=-3 and x=5 are $F(-3)=-27$ and $F(5)=125$

B) To find the domain of f :

The domain of the f in the given expression is the set of all real numbers except where the expression $x^3$ is undefined. In this case, there is no real number that makes the expression undefined.

The domain of f is the set of all real numbers
