what is the point slope form of an equation with the slope of 3/5 that passes through the point (10,-2)?

Mama L [17]

Point slope form of a line:
$y-y_1=m(x-x_1)$ where $m$ is your slope and $(x_1,\ y_1)$ is a point on your line.

For a line with a slope of 3/5 that passes through (10, -2)...
$m=\frac35,\ x_1=10,\ y_1=-2$
Let's plug these values into our formula.

$y-(-2)=\frac35(x-10)$

Subtracting by a negative is the same thing as adding (the double negatives cancel), so let's simplify that.

$\boxed{y+2=\frac35(x-10)}$

There's our equation in point-slope form. (keep in mind that you're not going to want to distribute that 3/5 or subtract the 2 or anything. You want to keep it similar to the formula.

The waverly company issued 4,000 shares of common stock worth 200,000.00 total. What is the par value of each share?

yuradex [85]

The value per share is 50 per share.

In order to find this, you take the total value of the stock and then divide by the number of shares.

200,000/4,000 = 50.

Therefore, it is 50 per share.

Help please with math

Mashutka [201]

Answer:

If they want irregular fractions its

1= 14/4 . 2= 11/2 3= 14/8

4= 21/4 . 5= 27/6 . 6= 125/13

7= 61/9 . 8= 69/9 . 9= 84/8

If they just want the few simplified then

1= 3 1/2

3= 1 3/4

5= 4 1/2

8= 7 2/3

9= 10 1/2
