Solve the absolute value equation. |3x-4|=5

Answers

Answer 1

Answer: Absolute values are a way of finding a distant from zero, which means there will be 2 answers; one will be positive, and the other will be negative.

$|3x-4|=5 and |3x-4|=—5$ Because you need 2 answers, you have to make 5 positive and negative.

Another way to write this equation would be...
5=|3x-4|=—5

Now lets continue...
5=3x-4=—5

Add 4 to both sides...
9=3x=—1

Now divide by 3...
3=x= $- (1)/(3)$

So the solution is...
X={ $-(1)/(3)$ , 3}

The base of a cube is parallel to the horizon. A plane cuts through the cube creating a pentagon-shaped cross section. Which kind of plane could it be? A. a vertical plane cutting two adjacent edges of the base B. a vertical plane cutting two opposite edges of the base
C. a slanting plane cutting two adjacent edges of the base
D. a slanting plane containing exactly one edge of the cube

Answers

I think the answer is C. a slanting plane cutting two adjacent edges of the base. I thought of the Pentagon building in Washington where it also has a pentagon-shaped cross section.

Answer:

C. a slanting plane cutting two adjacent edges of the base

Step-by-step explanation:

The base of a cube is parallel to the horizon. A plane cuts through the cube creating a pentagon-shaped cross section. The plane could be - a slanting plane cutting two adjacent edges of the base.

Priya is playing a game where she earns online badges for scoring higher than the mean score on a level. After the tenth level, she scores 3,540 points, which is 2 standard deviations above the mean score of 3,110 points.What is the standard deviation of scores for the tenth level?

a.)215
b.)311
c.)354
d.)430

Answers

If score of 3,540 points is 2 standard deviations above the mean score of 3,110, then:
3,110 + 2 s= 3,540
2 s = 3,540 - 3,110 = 430
s = 430 : 2
s = 215
Answer: A) The standard deviation is 215.

The standard deviation of scores for the tenthlevel is 215 and is denoted as option A.

What is Standard deviation?

This is defined as the measure of the amount of variation or dispersion of a set of values.

We were told that score of 3,540 points is 2 standard deviations above the mean score of 3,110 therefore,

3,110 + 2 s= 3,540

2 s = 3,540 - 3,110

2s = 430

s = 430/2

s = 215

Let x^2−12x=61 . What values make an equivalent number sentence after completing the square? Enter your answers in the boxes. HELP PLEASE

Answers

Complete the square:

x^2 - 12x + (-6)^2 - (-6)^2 = 61, or
(x-6)^2 -36 = 61, or

x-6 = plus or minus sqrt(97), or

x = 6 plus or minus sqrt(97)

A=1 , b=-12 , c=61. B^2-(4 •a•c) = d
-12^2-(4•1•61)= d
X= (-b-sqr (d) ) / 2a or x=(-b+sqr (d) )/2a
