The slope-intercept form:
m - slope
b - y-intercept → (0, b)
We have the point (0, 5). Therefore b = 5.
We have: y = mx + 5
Other point (3, 2). Substitute the coordinates of the point to the equation of the line:
<em>subtract 5 from both sides</em>
<em>divide both sides by 3</em>
<h3>Answer: f(x) = -1x + 5 = -x + 5</h3>
Answer:
23
Step-by-step explanation:
Suppose,
the first number = x
the second number = x+1
the third number = x+1+1 = x+2
Question wise,
x+x+1+x+2 = 72
3x+3 = 72
3x = 72-3 = 69
x = 69/3 = 23
so the numbers are,
23,(23+1)=24 and (23+2)=25

Answer:
Perimeter of the circle = 31.42 in(exact value) ≈ 31.40 in (approximate value)
Area of the circle = 78.55 in²
Step-by-step explanation:
Given:
Radius = 5 in
To Find:
Area & Perimeter of the circle
Solution:
<h3><u>Perimeter </u><u>of </u><u>the </u><u>circle</u><u>:</u></h3>
We know that,
Taking π as 3.142 and substituting values,we obtain
- Perimeter = 2*5*π
- Perimeter = 10π
- Perimeter = 10*3.142
- Perimeter = 31.42 ≈ 31.40 in
<h3><u>Area </u><u>of </u><u>the</u><u> circle</u><u>:</u></h3>
We know that,
- Area = πr²
- Area = π(5²)
- Area = 25π
- Area =25*3.142
- Area = 78.55 in²
