Answer:
Function 2, because Ricky spends $7 each week and Tony spends $6 each week
Step-by-step explanation:
You find the rate of weekly rate of change by calculating the difference of the amount changing each week:
24 - 30 = - 6
18 - 24 = - 6
12 - 18 = - 6
As you see the rate of change is constant: - 6 dollars per week. This means that Tony is spending 6 dollars every week
Function 2: y = –7x + 30
The rate of change is the slope (m) of the linear function, and this is the coefficient of the independent variable, x.
This equation is written in slope intercept form (y= mx+b)
Then the rate of change is - 7 dollar per week. This means Ricky spends 7 dollars every week.
Now you know that the two rates are constant and that the second function shows a steeper decreasing.
A non zero real number could be written as a/1.
When this gets reversed to be 1/a, it is the multiplicative inverse.
You do 6/4 to find that each friend gets 3/2 or 1.5 apples
Logan's swimming average is 2.25 kilometers per hour.
Mila's swimming average swimming speed is 34.44 m/min.
The distance swam by Logan = 750 m
The distance swam by Mila = of Logan's distance = × 750 = 2 × 250 = 500.
Answer: 1
Step-by-step explanation:K
To make the expression a perfect square, wenwed to add to the expression the square of half the coefficient of the x which is 2
Now we have
x² + 2x + (2/2)²
x² + 2x +1²
x²+ 2x + 1,
So we need to add 1 to make the expression a perfect square.
