No it doesn’t because the coordinate plane doesn’t represent a function.

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!

What is the slope of a line parallel to the line with equation 2x+4y=8

bagirrra123 [75]

Answer:

m = $\frac{-1}{2}$

Step-by-step explanation:

To find the slope of most lines, we should rearrange the equation into the slope-intercept form or y = mx + b.

So,

2x + 4y = 8

4y = -2x + 8

$y=\frac{-2x +8}{4}$

$y=\frac{-2}{4}x+\frac{8}{4}$

$y=\frac{-1}{2}x+2$

The slope is the coefficient of the x term, so

m = $\frac{-1}{2}$

What is the value of x using the Pythagorean theorem?

Vesnalui [34]

A^2+b^2= c^2

Plug in the points. the longest side is always c.

95.2^2+ b^2= 168^2.

Square the numbers.

9063.04+ b^2= 28224

Subtract 9063.04 on both sides.

b^2= 19160.96

Find the square root.

b= 138.423119456

Or, b= 138.4 (rounded down)

Imani can pick forty bushels of apples in 15 hours. Bill can pick the same amount in 13 hours. Find how long it would take them

Delvig [45]

Answer:

6.96 hours.

Step-by-step explanation:

First, we need to find out the hour rate of bushels picked for each of them.

If Imani can pick 40 bushels in 15 hours, then he picks 40/15 = 8/3 bushes per hour.

If Bill can pick 40 bushels in 13 hours, then he picks 40/13 bushes per hour.

Working together, they pick: $\frac{8}{3} +\frac{40}{13}$ bushes per hour.

Let's simplify this expression:

$\frac{8}{3} + \frac{40}{13} = \frac{104+120}{39} = \frac{224}{39}$ = 5.74

Now we can use a rule of three

1 hour -------5.74

x hours ------40

Then,

x = 40 / 5.74 = 6.96

Therefore, it would take them 6.96 hours working together.
