A printing firm charged $35 for printing 600 sheets and $47 for printing 800 sheets find the formula assuming the relationship i
saveliy_v [14]
Here, Coordinates are: (35, 600) & (47, 800)
Now, Slope (m) = y2 - y1  /  x2 - x1
m = 800 - 600 / 47 - 35
m = 200 / 12 = 100 / 6
m = 50/3

Take any one coordinate into slope-intercept formula:
y - y1 = m(x - x1)
y - 600 = 50/3 (x - 35)
y - 600 = 50x/3 - 1750/3
y = 50x/3 + 50/3

In short, Your Answer would be: y = 50x/3 + 50/3

Hope this helps!

A fruit stand has to decide what to charge for their produce. They need $5 for 1 Apple and 1 orange. They also need $15 for 3 ap
lakkis [162]

Answer:

x + y = 5

3x + 3y = 15

Step-by-step explanation:

let x represent apple and y represent orange

Hence x + y = 5

and 3x + 3y = 15

Solving both equations simutaneously

From first equation, x = 5-y

Substitute x=5-y into the second equation

3(5-y)+3y = 15

y= 0

x = 5-0 = 5

Calculate the discriminant: 5x² + 2x − 2 = 0
Darya [45]

Answer:

44

Step-by-step explanation:

The equation is of the form  a x ²+bx +c = 0 where

a = 5, b= -2, c= -2

The Discriminant is given by:

Δ= b²− 4  * a  *  c

=  (−2²)−  ( 4  *  5  *  ( −  2 ) )

=  4 +  40

= 44
