Answer:

A) x= -4

Step-by-step explanation:

To solve you must isolate the variable. Do this by using the properties of equality to subtract and divide numbers from both sides of the equation. First, subtract 8x to move all x terms to the right side.

-48=12x

Then, divide both sides by 12

-4=x

Salim says he cannot simplify the expression a^m • a^n. Complete the statement about Salim's claim.
Shkiper50 [21]

Answer:

Salim can simplify that and the answer will be a^m^+^n

Step-by-step explanation:

This is because of the law of multiplying powers, which states that you can add the exponents if the base is the same. So, you just add m and n and put that as the exponent and you will have the answer.

B) Alfredo said that Angle 7 and Angle 6 are congruent and that would prove Line m
malfutka [58]

Answer:

Yes if Angle 7 and angle 6 are linear pairs in angles created by a straight line that cuts through parallel lines.

Step-by-step explanation:

Remember that two parallel lines that are cut by a transveral will create 8 angles, which will be similar to each other. Making four pairs of congruent angles means that they will be exactly the same angle located in different parts of the system. So if angles 6 and 7 are congruent, and the lines are cut by a transversal, then the lines are parallel.

Josh examines the expression 5^-x over 5^x, where m is greater than 0.
DochEvi [55]

Answer:

Josh is wrong.

Step-by-step explanation:

5^-x / 5^x  = 5^(-x-x) = 5^-2x

= 1 / 5^2x  

 (you subtract the exponents when dividing )

So Josh is wrong  ( he would be correct if we were multiplying)
