Papessa [141]

Answer:

y = -5x - 19

Step-by-step explanation:

Find the y intercept using slope intercept form [ y = mx + b ]

y = -5x + b

-4 = -5(-3) + b

-4 = 15 + b

-19 = b

y = -5x - 19

Answer:

The area of the pentagon is = 31.5

Step-by-step explanation:

First, we determine the perimeter of the "Pentagon" drawn in the attachment:

$p=4+4+4+4.5+4.5=21$

Now, we'll check the formula for pentagons:

$a=\frac{perimeter x apothem}{2}$

we calculate the apothem by placing a 90° angle in one of the sides of the shape. It is equal to:

apothem=3

then, we can substitute the values in the formula

$a=\frac{21(perimeter) x 3(apothem)}{2} =\frac{63}{2} =31 \frac{1}{2} or 31.5$

Let me know if you have questions :D

A clock loses 10 minutes each hour.

dusya [7]

Solution:

3:36 PM.

The clock loses 10 minutes each hour,

so it loses 5 minutes every half-hour,

and it loses 1 minute very 6 minutes.

It is 12:50 PM at 1:00 o'clock.

It is 1:40 PM at 2:00 o'clock.

It is 2:30 PM at 3:00 o'clock.

It is 2:55 PM at 3:30 o'clock.

It is 3:00 PM at 3:36 o'clock.

Hope it helped mah friend :)
