Answer:
Ariah needs 2748 kilograms of air to fill the balloon.
Step-by-step explanation:
Answer:
y = x - 2
Step-by-step explanation:
Using any two points to find the slope. I will using (3, 1) and (7, 5)
Slope = (change in the y values)/(change in the x values)
Slope = (5 - 1)/(7 - 3) = 4/4 = 1
Next find the y -intercept "b", using the table to find the value of y when x is zero. That point is (0, -2) . So the y-intercept ("b") is -2
or use one of the point (7, 5) and substitute into the slope- intercept formula and solve for "b'
y = mx + b
5 = 1(7) + b
5 = 7 + b
-2 = b
Write the equation in the slope-intercept form y = x - 2
To add decimals, line up the decimal points.
Here are some examples.
1.2
1.43
10.2
2.5
938.290
21.001
After you line up the decimal points, just add and carry down the decimal point.
14.37
5.63
_____
20.00
So, the answer is 20.
