Answer:
3x + 4y = -1
3x + 4y + 1 = 0
Step-by-step explanation:
-2x -4 = 2
x + 2y + 1 = 0
Answer:
8280 cal
Step-by-step explanation:
Q=mc(delta)T
Q=1200(0.115)(-60)
Q=8280 cal
I used 1200 g instead of 1.2 kg
Answer:
-4
Step-by-step explanation:
The equation for slope is as follows:
<h2>

</h2>
We can use point P and point V's coordinates to find the slope.
Point P is at (2,4)
Point V is at (3,0)
Let's define all the variables:
y2 = 0 (from point V)
y1 = 4 (from point P)
x2 = 3 (from point V)
x1 = 2 (from point P)
Now that we have all the variables we can plug it into the equation:

Therefore, the slope of line PV is -4.

P / 100 = 150 / 200 ;
p / 100 = 15 / 20 ;
p / 100 = 3 / 4 ;
p = ( 3 * 100 ) / 4 ;
p = 300 / 4 ;
p = 75 ;
p% = 75% ;
