Answer: <span>y - 37.5 = 2.5 ( x - 7)
Explanation:
1) The point-slope form is has this form:
y - y1 = m (x - x1)
Where m is the slope or rate of change and x1, y1 are the coordinates of the point.
2) you are told that the the rate of change of water (m) is 2.5
m = 2.5
3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:
x1 = 7
y1 = 37.5
</span>4) Replace those value in the point-slope model:
y - 37.5 = 2.5 ( x - 7)
That is the point-slope model or equation.
Answer:
25 a 18p
Step-by-step explanation:
4x5 5+5+4+4
A² = 14² + 48²
a² = 196 + 2304
a² = 2500
a = \/2500
a = \/(25*100)
a = 5*10
a = 50
Answer:
$11.03.
Step-by-step explanation:
5 % = 0.05.
The amount after 2 years
= 10(1 + 0.05)^2
= $11.03.
Answer:
The slope of the line. otherwise known as the gradient, can be found in the equation as the number in front of the x term.
In this case, it is - 1/2 (or -0.5, however you want to answer it)
