Answer:

-2.6

Step-by-step explanation:

Slope or gradient is the ratio of the vertical (y axis) and horizontal distances (x axis) between two points on a line.

It should be noted that it is defined as zero if the line is horizontal, but undefined if it is vertical.

Given:

Coordinates (- 3, 7) (2, - 6)

y1 = 7, y2= -6, x1= -3, x2=2

Slope : ∆ y/ ∆ x

= (y2 - y1 )/ (x2 - x1)

= (-6 - (7))/ (2 - (-3))

= (-13)/(5) = -13:5= -2.6

Answer:

\frac{13}{ - 5}

Step-by-step explanation:

\frac{y1 - y2}{x1 - x2}  \\  \frac{7 - ( - 6)}{ - 3 - 2}  \\  \frac{7 + 6}{ - 5}  \\  =  \frac{13}{ - 5}

$700 is invested at 4% per annum. How long will it take for the amount to reach $784?​
Blababa [14]

Answer:

3yrs

Step-by-step explanation:

Given parameters:

Capital = $700

Percentage interest  = 4% per annum

Unknown:

Time it will take for amount to be  = $784

Solution:

To find the simple interest on an amount;

        I = \frac{PRT}{100}

P is the principal

R is the rate

T is the time

I is the interest

    Insert the parameters:

        I  = \frac{700x 4 x T}{100}

        I = 28T

So;

   At the end of the duration:

       Principal + Interest  = Amount

          700+28T = 784

                   28T = 784 - 700

                   28T = 84

                       T = 3yrs

The graphs of the equations $y=3x-20$ and $y=-2x+10$ intersect at the point $(6,-2)$. Without solving, find the solution of the
Maru [420]

Answer:

The solution is

\boxed{x=6,y=-2}

Step-by-step explanation:


The given equations are


y=3x-20


and

y=-2x+10


The graph of the two equations intersects at (6,-2) as show in the graph in the attachment.


The point of intersection of the two graphs is the solution to system of equations.

Hence the solution is

x=6,y=-2
