Calculate the Y-Intercept

Calculate the Slope

Calculate the X-Intercept

Answer: Slope = -1.000/2.000 = -0.500

Hope this helps.

Answer:

slope = - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + 2y = - 8 ( subtract x from both sides )

2y = - x - 8 ( divide all terms by 2 )

y = - [tex]\frac{1}{2}[/tex] x - 4 ← in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Answer:

7x - 3y = -34

7x - 3(2) = -34

7x - 6 = -34

7x - 6 + 6 = -34 + 6

7x = -28

7x/7 = -28/7

x = -4

7(-4) - 3y = -34

-28 - 3y = -34

-28 + 28 - 3y = -34 + 28

-3y = -6

-3y/-3 = -6/-3

y = 2

Answer:

Asa forgot to floss for 106 days.

Step-by-step explanation:

First of all, we will start by writing out the details we are given clearly.

Length of floss used per day = 18 inches

Original length of floss bought for use = 50 ft = 600 inches

Number of days between March 17th and August 2nd = 138 days

Length of floss left after August 2nd = 2 feet = 24 inches

From this, we can clearly calculate the length of floss used.

This will be original floss length - length of floss remaining = 600 - 24 = 576 inches

Length of floss used = 576 inches

If Asa used 18 inches per day, we can find the number of days he flossed by  dividing the length used in total by the length used per day.

That will be 576/18 = 32 days

if Asa flossed for only 32 days, the number of days he didn't floss is 138 - 32 =106 days

Hence, Asa didn't floss for 106 days.

Answer:

€18.40 or £16.53.

Step-by-step explanation:

Kamil is saving up to buy a model of Big Ben costing £30 when he visits London.

He has saved €15.00.

First, we have to convert his savings to Pounds(£) and then, subtract that from the amount he needs.

€1  = £0.90

€15 = 15 * 0.9 = £13.47

So, Kamil has saved  £13.47.

Therefore, the amount he has left to save is:

£30 -  £13.47 =  £16.53

To find this amount in Euros, we convert it to Euros:

£1 = €1.11

16.53 = 16.53 * 1.11 = €18.40

He has to save €18.40 or £16.53.

Answer:

€18.3 or £16.49

Step-by-step explanation:

Kamil needs to save £30 to buy Big Ben. Current rate of conversion from pound to euro is £1 = €1.11. If the money is converted from pound to euro, you multiply it by 1.11.

Therefore £30 = € (30 * 1.11) = €33.3

If he has saved €15 he needs to save an extra of €(33.3 - 15) = €18.3

He needs to save €18.3

€18.3 to pound using the Current rate of conversion from euro to pound = £(18.3/1.11) = £16.49

Number of cones = Volume of Sphere/Volume of one cone

Volume of sphere = (4/3)πr³

[tex]=\frac{4}{3}\pi *10.5*10.5*10.5\\\\=4*\pi *3.5*10.5*10.5\\\\=1543.5\pi cubic cm[/tex]

Volume of cone= (1/3)πr²h

[tex]=\frac{1}{3}*\pi *3.5*3.5*3\\\\=\pi *3.5*3.5\\\\=12.25\pi cubic cm[/tex]

Answer:

The angle for each slice is 45 degrees.

Step-by-step explanation:

In order to calculate the angle of each slice, we first need to calculate the total area of the pizza, because we will use that to find the area of each slice and as a result it's angle. To calculate the area of the pizza we must use:

pizza area = pi*r²

r = d / 2 = 14 /2 = 7 inches

pizza area = pi*(7)² = 153.86 square inches

Since the pizza was divided in 8 pieces, the area of each piece is given by the area of the pizza divided by the number of slices. We have:

slice area = pizza area  / 8 = 153.86 / 8 =19.2325 square inches

Each slice is a circle sector, therefore it's area is given by:

slice area = (angle*pi*r²)/360

Therefore we can solve for angle:

19.2325 = (angle*pi*7²)/360

angle*pi*49 = 6923.7

angle = 6923.7 / pi*49 = 45 degrees

The angle for each slice is 45 degrees.

Step-by-step explanation:

Answer:

His usual speed is 105 km/hr.

Step-by-step explanation:

Let his usually speed be s km/hr and the distance between the towns be d km. So we have the equations:

s =  d/6

s - 15 = d / (6 + 1)

from the first equation:

d = 6s and from the second:

d = 7(s - 15)

Eliminating d we get:

6s = 7(s - 15)

7s -  105 = 6s

s = 105.

Answer:

r=9

ef=55

Step-by-step explanation:

The value of r in the given parallelogram is 9 and the length of EF is 55 units.

A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

Given that, in a parallelogram FCDE sides DC and FE are parallel, and sides FC and ED are parallel. The length of CD is 4r + 19, the length of DE is 8r + 3, and the length of FC is 9r - 6.

Since, we know that,

Opposite side of a parallelogram are parallel and equal, therefore,

FC = DE and DC = FE

Therefore,

8r+3 = 9r-6

r = 9

Therefore,

FE = DC = 4r+19

= 36+19

= 55

Hence, the value of r in the given parallelogram is 9 and the length of EF is 55 units.

Answer:

(x -11) * t + 1067

Step-by-step explanation:

We know that in her tutoring job she earns x amount of money and how waitress earns $ 11 / hour.

They give us the combined number of hours that he works with all the jobs, which is 97, but from here we can say that in the time that he does NOT work as a tutor it is actually 97 - t.

Total earned this month = x * t + 11 * (97 -t)

Total earned this month = x * t + 1067 - 11 * t = (x -11) * t + 1067

Answer:

f(x)=2x

Step-by-step explanation:

You can get your (a)term by finding rise/run, and there is no y-intercept so the (b)term is not known. Thus you get f(x)=2x.

The equation of the line is [tex]y = 2 x[/tex]

From the graph, we have the following ordered pairs

(0,0) and (5,10)

The equation of the line is calculated using

[tex]y = \frac{y_2 -y_1}{x_2 -x_1} \times (x -x_1) + y_1[/tex]

So, we have:

[tex]y = \frac{10 - 0}{5 - 0} \times (x -0) + 0[/tex]

[tex]y = \frac{10}{5} \times (x -0)[/tex]

[tex]y = 2 \times x[/tex]

Evaluate the product

[tex]y = 2 x[/tex]

Hence, the equation of the line is [tex]y = 2 x[/tex]

Answer:0.0019g

Step-by-step explanation:

Answer:

I can't post a graph, but I will explain how to do it.

Step-by-step explanation:

The y intercept is 3, so we know we can place a point at the coordinates (0,3). The y intercept is the point where your line crosses the y axis.

The slope is -3, which is the same as -3/1. The top number is the y axis, the bottom number of the slope is the x axis. This tells us that for every 1 space we move on the x axis, we move -3 spaces on the y axis. You should therefore have a second point located at (1,0).

You should end up with a line with a point at (0,3) and (1,0) which slopes down from left to right. Hope that helps.

The line of the graph is y=-3x+3

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Slope is -3 and y-intercept is 3.

y=-3x+3

Now we have to plot the graph

x   0      1     2    3     4

y    3     0    -3   -6   -9

Hence, the line of the graph is y=-3x+3
