Answer:
y+2x=4
Step-by-step explanation:
use the formula of equation of line
The equation of line is y= 4 - 2x.
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given co- ordinates:
A(-1,6) and B (3,-2)
slope = [tex](y_2 - y_1) / (x_2 - x_1)[/tex]
slope = ( -2 - 6)/ ( 3 -(-1))
slope = (-8) / (4)
slope = -2
Now, the equation of line
([tex]y-y_1) = m (x - x_1)[/tex]
(y- 6) = (-2)(x - (-1))
y-6 = (-2)(x + 1)
y-6 = -2x -2
y= 4 - 2x
Hence, the equation of line is y= 4 - 2x.

Find the volume of this composite figure
Answers
Answer:
381 feet cubed
Step-by-step explanation:
You need to divide the shape into 2.
I would divide the shape so that 8.5ft, 6ft, and 3ft are one.
Now do Length times Width times Height for the first one.
8.5 ft x 6 ft x 3 ft = volume for shape 1
The volume for shape 1 is 153 feet cubed
Now onto the second one.
Since you divide the other shape to have 8.5 feet the measurements are:
4ft, 9.5ft, and 6ft.
Do the formula lwh.
4ft x 9.5ft x 6ft = volume for shape 2
The volume for shape 2 is 228 feet cubed
Finally, you have to add shapes 1 and 2 due to the fact it's a composite figure.
153ft + 228ft = 381ft cubed

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
here, we have,
Given that the area is 1.78 × 10⁷ km² with 3.50 × 10^8 people.
The population density will be calculated as below:-
Density = people / km² = ( 3.50 × 10^8 ) / ( 1.78 x 10⁷ )
Density =19.66
Density = 19.66 people/km²
Therefore, the population density will be equal to 82.96 people/km2. The correct option is A.

Which number does NOT round to 880?
893
883
882
878
Answers
Answer:
893
Step-by-step explanation:
893 is too far away to round to 880. It would actually round to 890.
The last digits of 883 and 882 are small enough to round to 880.
The last digit of 878 is large enough to round to 880.
Answer:
893
Step-by-step explanation:
We round down if the digit is less than 5
We round up if the digit is 5 or more
Rounding to the nearest 10:
893 → 890 (round down as 3 is less than 5)
883 → 880 (round down as 3 is less than 5)
882 → 880 (round down as 2 is less than 5)
878 → 880 (round up as 8 is more than 5)
So the only number that does NOT round to 880 is 893.
