3(x + 2) = 7x + 6 - 4x

Answers

Hope this helps! (:

Answer:

(-∞,∞)

any value makes the equation true

(its infinite)

Step-by-step explanation:

3(x + 2) = 7x + 6 - 4x

distribute

3x + 6 = 7x + 6 - 4x

combine like terms

3x + 6 = 3x + 6

move the variable to the other side

0 + 6 = 6

move the 6

0 = 0

Solve for x: 3(x + 1) = -2 (x-1) - 4

Answers

Answer: x = -1

Remove parentheses

Calculate

Move the terms

collect like terms, calculate.

divide both sides.

Answer: x = -1

3(x + 1) = -2(x-1) - 4 (Expand by distributing)

3x + 3 = -2x + 2 - 4 (Rearrange the terms so that the terms with a variable of x are on one side)

3x + 2x = 2 - 4 - 3 (Collect like terms)

5x = -5 (Divide both sides by 5 to isolate for x)

x = -1

∴ x = -1.

Write the equation in slope intercept form: 3x - 4y = 8*

Answers

Answer:

the answer is y=[tex]\frac{3}{4}[/tex]x-2

Step-by-step explanation:

The equation 3x - 4y = 8  written in slope-intercept form as y = (3/4)x - 2.

To write the equation 3x - 4y = 8 in slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept,  to isolate y on one side of the equation.

Starting with the given equation:

3x - 4y = 8

First, let's subtract 3x from both sides of the equation to isolate the y term:

-4y = -3x + 8

Next, divide both sides of the equation by -4 to solve for y:

y = (3/4)x - 2

Now the equation in slope-intercept form. The slope is 3/4, and the y-intercept is -2.

A water tank holds 648 gallons but is leaking at a rate of 4 gallons per week. A second water tank holds 864 gallons but is leaking at a rate of 7 gallons per week. After how many weeks will the amount of water in the two tanks be the same?


The amount of water in the two tanks will be the same in ________ weeks.

Answers

Answer:

The first tank contains

486 gal - (4 gal/week) t

gal of water after t weeks.

Similarly, the second tank contains

648 gal - (7 gal/week) t

gal of water.

The tanks hold the same amount of water when these two amounts are equal:

486 gal - (4 gal/week) t = 648 gal - (7 gal/week) t

(7 gal/week) t - (4 gal/week) t = 648 gal - 486 gal

(3 gal/week) t = 162 gal

t = (162 gal) / (3 gal/week)

t = 54 weeks

An airplane pilot over the Pacific sights a ship wreck at an angle of depression of 5°. At this time, the horizontal distance from the airplane to the wreck is 4629 meters. What is the height of the plane to the nearest meter?





405 m

Answers

Answer:

The height of the plane is 405 meters

Step-by-step explanation:

Trigonometric Ratios

The situation can be represented as shown in the image below. The ground, the height H, and the direct distance to the plane to the shipwreck form a right triangle, where the trigonometric ratios stand.

Since the known distance is adjacent to the angle, and the required height is opposite to the given angle, we use the tangent ratio, defined as:

[tex]\displaystyle \tan\ x=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

[tex]\displaystyle \tan 5^\circ=\frac{H}{4629}[/tex]

We need to find H, so we solve for H:

[tex]H=4629\cdot\tan5^\circ[/tex]

H=405 m

The height of the plane is 405 meters

Answers

Complete question is;

Some car jacks are constructed like a collapsed rhombus. When used to raise a car, the rhombus is easily seen. If the sides of the rhombus are 15 inches, what is the maximum length of the shaft?

Answer:

Maximum length of shaft = 30 inches

Step-by-step explanation:

To understand this clearly, I've attached a real life image of a car jack that's in the shape of a rhombus.

From the attached image, we can see that it has four sides which are equal in length.

Now, if this jack is collapsed, the shaft will just be like a straight line with a maximum length equal to twice a side of the rhombus which represents the maximum length of the diagonal.

Since we are told that one side of the rhombus is 15 inches, it means that the maximum length of shaft = 2 × 15 = 30 inches

What is decimal in numeral system ?

The decimal numeral system is the standard system for denoting integer and non-integer numbers. It is the extension to non-integer numbers of the Hindu–Arabic numeral system. The way of denoting numbers in the decimal system is often referred to as decimal notation. A formal way to read decimals is to read the whole part as a whole number, then the decimal dot as “and” and then reading the fractional part altogether but using the place value of the last digit with it.

= (7x1)+(4x1/10)+(6x1/1000)

= 7 + 0.4 + 0.006

= 7.406

therefore , the decimal form of the expression is 7.406
