Mathematics

Artist 52 [7]3 years ago

The value is 3

Step-by-step explanation:

To simplify the expression -\frac{3}{4} \div \frac{2}{-8}, we can reciprocal the term \frac{2}{-8} to \frac{-8}{2} and multiply, so that we can easily simplify the terms.

Thus, the expression becomes,

-\frac{3}{4} \times \frac{-8}{2}

Multiplying the terms, we get,

\frac{24}{8}

Dividing the terms,

\frac{24}{8}=3

Thus, the value of the expression is 3.

Answer:   x = 8

                (the correct answer was not provided as an option)

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

log_2(x-6)+log_2(x-4)=log_2(x)\\\\log_2[(x-6)(x-4)]=log_2(x)\\\\(x-6)(x-4)=x\\\\x^2-10x+24=x\\\\x^2-11x+24=0\\\\(x-3)(x-8)=0\\\\x=3\qquad x=8\\\\\\\text{The term after the log symbol  (inside the parenthesis) must be greater than 0!}\\\\Check:\\3-6>0\ \text{FALSE --- so 3 is not a valid solution}\\\\8-6>0\ \text{TRUE}\\8-4>0\ \text{TRUE}\\8>0\ \text{TRUE --- 8 is a valid solution because it is true for all}

Step-by-step explanation:

Complete question below:

Consider the following expression and determine which statements are true. x^2+5yz−8

CHOOSE 2 ANSWERS)

A.there are 3 terms.

B.the variables are x, y, and z.

C.The coefficient of x is 2.

D.the term 5yz is made up of 2 factors

The expression x^2+5yz-8

has three terms namely: x^2, 5yz and -8

The variables are x, y and z

The coefficient of x is 1 not 2, so option c is wrong

The term 5yz is made up of more than two factors namely 5, y, z, 5y, 5z, 5yz . So option d is also wrong.

The correct answers are option a and option b

A.there are 3 terms.

B.the variables are x, y, and z
