Answer:

See explanation and picture below.

Step-by-step explanation:

When the storm began, there was an inch of snow on the ground.

The time on the graph is the number of hours since the storm began.

At the time the storm began, no time had passed since the storm began, so at the time the storm began, time was zero. At zero time, the snow was 1 inch. That gives you the point (0, 1).

For the next 6 hours, snow fell at a constant rate of 1 inch per hour.

At time 1 hour, there were 2 inches of snow. Point: (1, 2).

At time 2 hours, there were 3 inches of snow. Point (2, 3).

At time 3 hours, there were 4 inches of snow. Point: (3, 4).

At time 4 hours, there were 5 inches of snow. Point (4, 5).

At time 5 hours, there were 6 inches of snow. Point: (5, 6).

At time 6 hours, there were 7 inches of snow. Point (6, 7).

The storm then stopped for 3 hours. That means for the next 3 hours after time 6 hours, the snow stayed at 7 inches.

Points: (7, 7), (8, 7), (9, 7).

Then the storm started up again dropping 3 inches of snow per hour for the next 4 hours.

That gives us the next 4 points, in which the hour goes up one by one, and the snow goes up three by three.

Points: (10, 10), (11, 13), (12, 16), (13, 19).

Now you need to plot all the points in bold above and connect them with line segments.

See the picture below.

Select the number line model that matches the expression -2/3 - 5/3

Answers

Answer:

  C.  None of the above

Step-by-step explanation:

You want an number line representation of the expression |-2/3 -5/3|.

Value

The expression is evaluated by performing the sum -2/3-5/3, then finding its absolute value. The sum is -7/3, and its absolute value is 7/3.

None of the number line diagrams shows the sum or its absolute value.

__

Additional comment

The sum would be shown by moving from 0 to -2/3, then moving an additional -5/3 to the point -7/3. The absolute value would reflect that across the 0 point to +7/3.

Find the slope and the y-intercept of the graph of y=6x-5.

Answers

Answer:

slope: 3 ||   y-intercept: 9.4

Step-by-step explanation:

Given equation:

y - 1 = 3x + 8.4

y = 3x + 8.4 + 1

y = 3x + 9.4

Comparing with the formula of slope intercept form: y = mx +b

                                                  where m is the slope and b is the y-intercept.

So here the slope: 3 and y-intercept is 9.4

Answer:

y = 6x - 5

Slope - 6

Y-Intercept - (-5)

y - 1 = 3x + 8.4

Slope - 3

Y-Intercept - 9.4

x=-3y+13

Step by Step Solution

System of Linear Equations entered :

[1] -4x - 3y = -7
[2] 16x - 3y = 13
Graphic Representation of the Equations :

-3y - 4x = -7 -3y + 16x = 13



Solve by Substitution :

// Solve equation [2] for the variable x


[2] 16x = 3y + 13

[2] x = 3y/16 + 13/16
// Plug this in for variable x in equation [1]

[1] -4•(3y/16+13/16) - 3y = -7
[1] - 15y/4 = -15/4
[1] - 15y = -15
// Solve equation [1] for the variable y


[1] 15y = 15

[1] y = 1
// By now we know this much :

x = 3y/16+13/16
y = 1
// Use the y value to solve for x

x = (3/16)(1)+13/16 = 1
Solution :
{x,y} = {1,1}

Answer:

 x=1   y=4

Step-by-step explanation:

1.  4x+3y=16

   x=-3y+13

2. 4x+3y=16

    x+3y=13

3.  4x+3y=16

     -x-3y=-13

4.  3x=3

6. (1)=-3y+13

7.  1-13=-3y

8.   -12=-3y

Plot an open hole at -6; shade to the right

The open hole is because we don't include -6 itself.

The shading to the right indicates all numbers larger than -6.

Answer:

mark an open dot on -6 then make a line going to the right

Step-by-step explanation:

if the inequality sign is facing the variable (x) then the values will get bigger.

So the direction of the line will go to the right because the values are getting bigger going to the right

Answers

you can solve this using pythagoras theorem which states that the sum of the square of the lengths of the sides adjacent to the right angle is equal to the square of the length of ypotenuse (hypotenuse is the longest side which is opposite to right angle)

( the attached image will help you understand the theorem better)

so

20² + 15² = x²

400 + 225 = x²

625 = x²

√625 = x

25 = x

X=25

A certain type of bacteria reproduces so that after x hours there are 15x cells. What single power represents he size relationship between the cell population after 24 hours and the cell population after 8 hours? Show your work

Answers

Answer:

let's say cells is c and hours are x that means there are 15 cells each hour. the equation for that is c=15x

after 08 hours the cells have multiplied 8 times their original size. meaning that the equation changes to this: c=15x          x=8    c= 15(8)

x equals 8 at that time.. literally

ok the cells have multiplied and now there are 120 cells in total

then after one day the cells have multiplied over 12 times afterwards. now x equals 24. the equation would look a little like this:

c=15x      x=24    c= 15(24)

there are 360 cells now.

Explain in your own words the relationship between x=8 with x=24 in the equation.

Answer:

Step-by-step explanation:

a) input is 2

2 * 3/4 = 6/4

(6/4) / (2/3) = 18/8 or 2.25

b) output is 1/2 (this time we go backwards)

if it is multiply we divide and if it is divide we multiply

1/2 * (2/3) = 2/6        (it said divide by 2/3 so we multiply)

(2/6) / (3/4) = 8/18 or 4/9        (it said multiply by 3/4 so we divide)
