y= 3/2 x+ 3 and 3x-2y=-6

Step-by-step explanation:

□y = -3/2x-9

□y=3x+3

□3x+2y=-9 = y=-9/2 -3/2x

□y=3/2x+3 correct

□3x-2y=-6 = y=3+ 3/2x correct

□2/3x +3

Answer:

-2= 1/5x-2 +9

Step-by-step explanation:

Answer:

I think it´s D

Step-by-step explanation:

Distance covered is 168 km .

Time taken is 4 hours .

Speed = distance covered / time taken

=168/4

=42 kmph

In 80 minutes or 4/3 hours it would cover

42*4/3

=14*4

=56 km

Step-by-step explanation:

Let y be 1/x. Then 2y = 2/x.

We wish to simplify (1 + y)(2 - 2y)(2y).

(1 + y)(2 - 2y)(2y)

= 4y(1 + y)(1 - y)

= 4y(1 - y²)

= 4y - y³

= 4/x - 1/x³.

P.S. Writing it as (4x² - 1)/x³ is fine.

A. makes the most sense out of all of them. But if it had to be another one, I'd say D. Sorry! I'm not the best at these either. :)

Answer:

5 inches per hour

Step-by-step explanation:

Answer: 5 inches per hour

Step-by-step explanation:

Starting height of 16 minus the end height of 3.5.

16- 3.5= 12.5

Take this number and divide it by the time the candle burned (2.5 hours)

12.5 inches/ 2.5 hours = 5 inches per hour

Answer:

n = 3p

Step-by-step explanation:

12n + 7p - 6n = 25p; solve for n

First we will add like terms in the left side

12n - 6n + 7p = 25p

6n + 7p = 25p

Subtract 7p to both sides

6n + 7p - 7p = 25p - 7p

6n = 18p

Now divide 6 from both sides

6n/6 = 18p/6

n = 3p

Answer:

Replace all occurrences of +− with a single −. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because  1⋅−1 = −1

Y=x²−10, Y=2x−4

Eliminate the equal sides of each equation and combine.

x²−10 = 2x−4

Solve x²−10 = 2x−4 for x.

x= 1+√7, 1−√7

Evaluate Y when x = 1 + √7.

Y =−2 + 2√7

Evaluate Y when x = 1 − √7.

Y=−2 − 2√7

The solution to the system is the complete set of ordered pairs that are valid solutions.

(1+√7,−2+2√7)

(1−√7,−2−2√7)

The result can be shown in multiple forms.

Point Form:

(1+√7, −2+2√7), (1−√7, −2−2√7)

Equation Form:

x= 1+√7, y= −2+2√7

x= 1−√7, y= −2−2√7

Answer:

y = 3/2x + 7

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope.

The first line is 3x - 2y = 2. First, let's put this into standard form.

3x - 2y = 2

Add 2y to both sides to make y positive.

3x = 2y + 2

Subtract 2 from both sides to isolate y.

3x - 2 = 2y

Isolate y further by dividing both sides by 2.

3/2x - 1 = y or y = 3/2x - 1

This is now your first line. Its slope is 3/2. A line parallel to this one will also have a slope of 3/2.

Plug this value (3/2) into your standard point-slope equation of y = mx + b.

y = 3/2x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (-6, -2). Plug in the x and y values into the x and y of the standard equation.

-2 = 3/2(-6) + b

To find b, multiply the slope and the input of x (-6)

-2 = -9 + b

Now, add 9 to both sides to isolate b.

7 = b

Plug this into your standard equation.

y = 3/2x + 7

This equation is parallel to your given equation (y = 3/2x - 1) and contains point (-6, -2)

Hope this helps!

Answer:

Slope of the line       [tex]m = \frac{4}{3}[/tex]

Step-by-step explanation:

Explanation:-

Given points are ( 3,7) and (6,11)

Slope of the line

        [tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

       [tex]m = \frac{11-7}{6-3}[/tex]      

        [tex]m = \frac{4}{3}[/tex]

Slope of the line       [tex]m = \frac{4}{3}[/tex]
