V= m/d. When you get questions asking about density/mass/volume draw a triangle just like in the picture i have attached and with your finger cover up the one you are looking for. So to find the equation for volume you cover up volume and you are left with mass divided by density.
- Given, x > 0, y > 0.
- So, the values of x and y are less than 0, that means, they are negative integers.
- If we divide a Cartesian plane with the x-axis and y-axis, we get four quadrants.
- 1st Quadrant : (+,+)
- 2nd Quadrant : (-,+)
- 3rd Quadrant : (-,-)
- 4th Quadrant : (+,-)
- Since the values of x and y are both negative, so (x, y) is located in the <em><u>3rd Quadrant</u></em>.
Hope you could get an idea from here.
Doubt clarification - use comment section
U have a slope of 5/4...a perpendicular line will have a negative reciprocal slope...which means, the slope we need is -4/5.
Now we use y = mx + b
slope(m) = -4/5
(8,-7)
-7 = -4/5(8) + b
-7 = -32/5 + b
-7 + 32/5 = b
-35/5 + 32/5 = b
-3/5 = b
equation is : y = -4/5x - 3/5.....4x + 5y = -3
4x + 5y = -3....when x = 3
4(3) + 5y = -3
12 + 5y = -3
5y = -3-12
5y = - 15
y = -15/5
y = - 3 <===
Answer:
-1 Degree C
Step-by-step explanation:
When its talking about average temperature, its talking about the mean. To calculate mean, you add all the numbers and divide it by how many numbers are there.
(-8) + (-1) + 2 + 4 + (-2) = -5
mean = -5/5
-1 degree C
