9 tenths - 3 tenths =

amm1812

9 tenths - 3 tenths = 6 tenths. this is true the same way that 9 minus 3 = 6. In reality the tenths make both numbers decimals, but in this case the "tenths" is just a classification of the number and it doesn't effect the answer.

Find the slope of the line passing through the points (-5, 3) and (7,9).

dybincka [34]

Answer:

$\huge\boxed{slope=\dfrac{1}{2}=0.5}$

Step-by-step explanation:

The formula of a slope:

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

We have the points

$(-5;\ 3)\to x_1=-5;\ y_1=3\\(7;\ 9)\to x_2=7;\ y_2=9$

Substitute:

$m=\dfrac{9-3}{7-(-5)}=\dfrac{6}{7+5}=\dfrac{6}{12}=\dfrac{6:6}{12:6}=\dfrac{1}{2}$

Under Plan A a 2 minute call costs .54 cents a 4 minute call costs 1.08. Under plan b the cost for x minutes is given by y=0.289

Murljashka [212]

Answer: Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.

Step-by-step explanation:

1. You have the following information of Plan A:

- A 2 minute call costs .54 cents.

- A 4 minutes call costs $1.08.

2. For Plan B, you know that the cost of $x$ is given by the equation:

$y=0.289x$

3. Therefore, you can compare both plans by finding the cost of a call of 2 minutes and a call of 4 minutes of Plan B. You can calculate this by giving these values to $x$ :

$x=2\\x=4$

4. Substitute the values into the equation:

$y=0.289(2)=0.578cents$ (This is more expensive)

$y=0.289(4)=1.156dollars$ (This is more expensive)

5. Therefore, Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.
