Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

To find the slope of linear functions using two points, we have the following equation :

slope =  \frac{y(b) - y(a)}{ x(b) - x(a) } \\

Where a and b are two point of the function.

_________________________________

Step (2)

Well now I want to choose a name for the given points :

a = ( -3 , -3 ) ••••••••• b = ( -18 , -23 )

_________________________________

Step (3)

It's time to put the the coordinates in the above equation :

slope =  \frac{ - 23 - ( - 3)}{ - 18 - ( -  3)} \\

slope =  \frac{ - 23 + 3}{ - 18 + 3 } \\

slope =  \frac{ - 20}{ - 15} \\

Negatives simplified :

slope =  \frac{20}{15} \\

The face and denominator are reduced to five :

slope =  \frac{4}{3} \\

_________________________________

And we're done.

Thanks for watching buddy good luck.

The value of a car is $30,000 and depreciates at a rate of 6.5% each year.
navik [9.2K]

Answer:$20250

Step-by-step explanation:

6.5% of 30000

6.5/100 x 30000

(6.5 x 30000)/100

195000/100=1950

First year depreciation 30000-1950=28050

Second year=28050-1950=26100

Third year=26100-1950=24150

Fourth year=24150-1950=22200

Fifth year=22200-1950=20250

Find the VOLUME of this composite solid.
Black_prince [1.1K]

Answer:

  (294π +448) cm³ ≈ 1371.6 cm³

Step-by-step explanation:

The half-cylinder at the right end has a radius of 7 cm, as does the one on top. Together, the total length of these half-cylinders is 8 cm + 4cm = 12 cm. That is equivalent in volume to a whole cylinder of radius 7 cm that is 6 cm long.

The cylinder volume is ...

  V = πr²h = π(7 cm)²(6 cm) = 294π cm³

__

The cuboid underlying the top half-cylinder has dimensions 4 cm by 8 cm by 14 cm (twice the radius). So, its volume is ...

  V = LWH = (4 cm)(8 cm)(14 cm) = 448 cm³

Then the total volume of the composite figure is ...

  (294π +448) cm³ ≈ 1371.6 cm³

Urgent help!!! <br><br> Write equation in slope intercept form.<br><br> 1.25 (25) = 31.25
Fantom [35]

The equation in slope intercept form is,31.25 = 1.25 \times 25 +0. The given equation is obtained by comparing the standard equation of the straight line.

<h3>What is a slope of a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\rm m =\dfrac{y_2-y_1}{x_2-x_1}

The given equation is;

1.25 (25) = 31.25

31.25=1.25 (25)

The standard equation of the slope intercept form. is;

\rm y = mx +x

On comparing the given equation with the above equation, we get;

y=31.25

m=1.25

x=25

c=0

The equation in slope intercept form is;

31.25 = 1.25 \times 25 +0

Hence, the above equation is the slope intercept form.
