The perimeter of any shape is just what you get when you add up all of the side lengths. We know that one side is 462 meters, and since a square has four equal sides, we can just mulitply 462 × 4 to get our perimeter, 1,848 meters.
Choose the correct set of y-values for the function y = -2x when x = -2, 0, 2. (-2, -4), (0, 0), (2, -4) (-2, 4), (0, -2), (2, 4

Answer:
x = -2
(-2 , 4)
x = 0
(0 , 0)
x = 2
(2 , -4)
Step-by-step explanation:
y = -2x
we have to discover the value of y for when x is worth (-2, 0, 2)
so let's replace the x with each one and write your ordered pair
1) x = -2
y = -2x
y = -2(-2)
y = 4
( x , y)
(-2 , 4)
2) x = 0
y = -2x
y = -2(0)
y = 0
( x , y)
(0 , 0)
3) x = 2
y = -2x
y = -2(2)
y = -4
( x , y)
(2 , -4)
so we have that for each value of x we have a different ordered pair
Answer:
A decimal number can be divided in a decimal part, a whole part and the decimal point which separates the first two.
So, all numbers that are placed leftside of the decimal point can be classified in units, tens, hundreds, thousands, and so on. Basically, each value depends on a base of 10. This means that thousands are ten times more than hundreds, hundreds are ten times more than tens, tens are ten times more than units.
If we want to a specific value of the whole part in a decimal number, we just need to look units, tens, hundreds, thousands or millions.
For example, if we have the number 1235.8456, the whole part would be 1235, and the value of the numbers that are leftside of the decimal point is 1235 units.
Answer:
y = 9x - 40
Step-by-step explanation:
Using the point-slope equation of a straight line is the fastest approach here, since we already have the slope and a point:
y - k = m(x - h) becomes y - 5 = -9(x + 5)
Solving for y, this becomes y = 9x + 5 - 45, or y = 9x - 40
