What would be the steps taken to solve (x+3)^2-1=35

vodka [1.7K]

Answer:

Step-by-step explanation:

(x+3)^2=35+1

(x+3)^2=36

(x+3)^2=6^2

taking squareroot

x+3=+-6

x+3=6,-6

x=6-3=3

or x=-6-3=-9

A jeweler is dividing

Anuta_ua [19.1K]

Answer: OPTION D: $\frac{3}{32}$

Step-by-step explanation:

By definiton, fractions have the following form:

$\frac{a}{b}$

Where "a" is called numerator and "b" is the denominator. The numerator and the denominator are Integers.

In order to solve this exercise you need to remember de Division of fractions:

$\frac{a}{b}\div\frac{d}{e}=\frac{a}{b}*\frac{e}{d}=\frac{a*e}{b*d}$

In this case, according to the information given in the exercise, you know that $\frac{3}{8}\ lb$ of rubies are divided into 4 lots.

Therefore, in order to calculate the weight in pounds of each lot, you need to divide $\frac{3}{8}\ lb$ by 4.

Then, you get the following result:

$\frac{3}{8}\ lb\div4=(\frac{3}{8}\ lb) (\frac{1}{4})=\frac{3}{8*4}\ lb=\frac{3}{32} \ lb$

As you can notice, this result matches with the Option D.

natima [27]

Complete Question:

Select all of the pieces of information that would tell you x and y have a proportional relationship.

Let y represent the distance between a rock and a turtle's current position in meters and x represent the number of minutes the turtle has been moving. y=3x

1. After 4 minutes, the turtle has walked 12 feet away from the rock.

2. The turtle walks for a bit, then stops for a minute before walking again.

3. The turtle walks away from the rock at a constant rate.

Answer:

1. After 4 minutes, the turtle has walked 12 feet away from the rock.

3. The turtle walks away from the rock at a constant rate.

Step-by-step explanation:

Given

$y = 3x$

Required

Determine which of the options answers the question

Recall that:

$y = distance$

$x = time$

Analyzing the options 1 after the other:

Option 1:

In this option, we have that:

$y = 12$

$x = 4$

Substitute these values of x and y in the given equation

$y = 3x$

$12 = 3 * 4$

$12 = 12$

Because both sides of the equation are equal, this option shows a proportional relationship

Option 2:

The given equation cannot be used to ascertain the information given in this option.

Because for a every time (in minutes) traveled by the turtle, there's a corresponding distance moved.

Option 3:

Recall that

$y = 3x$

Assume $x = 5$

y would be

$y = 3 * 5$

$y = 15$

Assume $x = 6$

y would be

$y = 3 * 6$

$y = 18$

For every values of x and corresponding y value, there exist a constant relationship because:

$\frac{y}{x} = 3$

This implies that the rate at which the turtle moved is 3ft/s and this rate is constant.
