Answer:

Step-by-step explanation:

Simplify the expression.

Rewrite 64 as 8^2

Apply the power rule and multiply exponents, (am^)n = a^mn

8^2(1/2)

Cancel the common factor of 2

Rewrite the expression.

8^1

Evaluate the exponent.

Hope that helps!

Answer:

Step-by-step explanation:

When a quantity is raised to a fractional power, you need to root it to the power of the denominator.

For example, (-64)^(1/2) = √(-64) 

Since you are taking the root of a negative, you will need to put an i (imaginary) in your answer.

Answer: 6+4x=26, 4x=20

Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.

If you solve the equation, 2x+3=13 (subtract 3 from both sides)

2x=10 (divide both sides by 2)

x equals 5.

if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.

What is the value of x

il63 [147K]

the 2 angles are congruent so...

x+40=3x set the 2 equations equal to each other

40=2x subtract x from both sides

20=x divide by 2

x=20 is the final answer

Have a blessed day!

Consider the linear function that is represented by the equation Y =-10x+6 and the linear function that is represented

Answer:

(a) The function that is represented by the equation y=-10x+6 has a steeper slope and a greater y-intercept

Step-by-step explanation:

If we take the "steepness" of the slope to be the absolute value of the slope, then the line y=-10x +6 has a slope with a steepness of 10.

The line y -36 - 8(x -4) has a slope with a steepness of 8, so the first line is steeper.

The line y=-10x+6 has a y-intercept of 6. The line y-36 =8(x -4) has a y-intercept of 4, so the first line has a higher y-intercept.

The appropriate description of the two lines is ...

The function that is represented by the equation y=-10x+6 has a steeper slope and a greater y-intercept
