Step-by-step explanation:
The intercepts are where the line crosses the x and y axes.
To find the x- intercept ( where the line crosses the x- axis) let y = 0 in the equation and solve for x, that is
0 + 5 = - 2x
5 = - 2x ( divide both sides by - 2 )
x = -
= - 2.5 ← x- intercept ⇒ (- 2.5, 0 )
To find the y- intercept ( where the line crosses the y- axis ) let x = 0 in the equation and solve for y, that is
y + 5 = 0 ⇒ y = - 5 ← y- intercept ⇒ (0, - 5 )
Here is the graph. A way you could graph this is notice how this equation is in point-slope form.
A line that passes through (x1, y1) and has slope m
y - y1 = m(x - x1)
Using the equation, you could find out that the line has a slope of -2/3 and passes through the point (-9,5).
Have an awesome day!
Answers:
13 42 m; B; 0.57 m
Step-by-step explanation:
Data:
Pool A: r = 22 ft
Pool B: D = 13.6 m
Calculations:
1. Radius of Pool A
r = 22 ft × (0.305 m/1 ft) = 6.71 m
2. Diameter of Pool A
D =2r = 2 × 6.71 = 13.42 m
The diameter of Pool A is 13.42 m.
3. Compare pool diameters
The diameter of Pool B is 13.6 m.
So, the diameter of Pool <u>B</u> is greater.
4. Compare circumferences
The formula for the circumference of a circle is
C = 2πr or C = πD
Pool A: C = 2π × 6.71 = 42.16 m
Pool B: r = π × 13.6 = 42.73 m
Pool B - Pool A = 42.73 - 42.16 = <u>0.57 m
</u>
The circumference is greater by <u>0.57 m.</u>
