Step-by-step explanation:

2x/3 -4 = x

multiply both side by 3

2x - 12 = 3x

-x = 12

x = -12

Answer:

x < 2

Step-by-step explanation:

Let's actually solve the given inequality 3x + 1 < 7.  First we want to combine the constants into one:  3x < 6.  Solving for x, we get x < 2.

The graph you have chosen as your answer is correct.  x does not equal 2, but rather is less than 2, as the given inequality states.  Since x is less than 2, we start at the (open) circle at 2 and move to the left.

According to the given information, the slope of the line is -1.

In mathematics, slope is a measure of how steep a line is, or how much y (vertical) changes for a given x (horizontal) change. It is represented by the letter "m" and is calculated as the change in y divided by the change in x, or rise over run. The slope can be positive, negative, zero, or undefined.

The answer is D, -1; the amount of water decreases by 1 gallon per minute.

To find the slope of the line, we need to use the slope formula:

slope = (change in y)/(change in x)

In this case, the change in y represents the change in the amount of water, and the change in x represents the change in time.

Option A says that the slope is 2/3, which means that for every 3 minutes, the amount of water decreases by 2 gallons. This is incorrect because as time increases, the amount of water should decrease, so the slope should be negative.

Option B says that the slope is -2/3, which means that for every 3 minutes, the amount of water decreases by 2 gallons. This is the same as option A but with a negative slope, which is correct because the amount of water decreases over time.

Option C says that the slope is -3/2, which means that for every 2 minutes, the amount of water decreases by 3 gallons. This is incorrect because the amount of water should decrease by the same amount every minute.

Option D says that the slope is -1, which means that for every minute, the amount of water decreases by 1 gallon. This is the correct answer because it describes a constant rate of change in the amount of water over time.

Therefore, according to the given information, the slope of the line is -1.

Answer:

5/2

Step-by-step explanation:

We know,

Equation of the slope is, y = mx + c.   Where m is the slope.

y - 4 = 5/2*(x-2)

y = 5/2*(x-2) + 4

y = (5/2)x - 5 + 4

y = (5/2)x - 1

y = (5/2)x + (-1)      [y = mx + c form]

Slope, m = 5/2

The longest side of a triangle is known as the hypotenuse

Answer:

teri maa ki chut me mera land madarchod sale gand marunga teri

Step-by-step explanation:

The point (12, 5)

x = 12, y = 5

=> r =√12²+5² =√144+25= √169=13

so, cos θ = x/r = 12/13 and

cot θ = x/y = 12/5

Answer:

t = [tex]\sqrt{r^2 + s^2}[/tex]

Step-by-step explanation:

Below is the following calculation:

It is given that the one side of the triangle is t. Thus, let the other sides are "r" and "s". Thus, the best way to find the side of a triangle is to use the Pythagorean theorem. Here, let t is the hypotenuse.

Below is the formula:

t = [tex]\sqrt{r^2 + s^2}[/tex]

Step-by-step explanation:

72 times 108 = 7776 sq inches

to convert inches to yds divide by 36

7776/ 36 = 216 sq yds

Answer: 6 yards^2

Step-by-step explanation:

first lets find the area of the space in inches and then convert the total to square yards :)

area = length * width

A = 108 * 72 = 7776 inches^2

now lets convert it

there are 1296 inches in a yard, so we divide 7776 by 1296 to find the number of square yards

7776 / 1296 = 6

so the area of the space is 6 yards^2

Answer:

Third option or 3,9,27,81

Step-by-step explanation:

A geometric sequence is a sequence where the term multiplies by the last term to make the next term.

In these options, we can clearly see the second and fourth one are not geometric as their relationship is not by multiplying.

The first option is also wrong since 4*-16 is -64, not 64.

That leaves the third option. 3*9 = 27, 9*27 is 81. Therefore, it is the third option

Answer:

A) r=d/t

B) 221,760 feet per hour

C) 42 miles per hour

D) in this scenario feet per mile makes more sense since the distance is listed in feet.

Step-by-step explanation:

A) you solve for r by divided both sides of the equation by (t)time

B) you take your formula r=d/t and substitute the values of (d) and (t) with 665,280 feet and 3 hours.

C) convert feet to miles by dividing the given amount of feet by 5280 since there are 5,280 feet in 1 mile

D) use feet to make the calculations easier and to avoid making a mistake in converting feet to miles
