Answer:
The equation of the line that passes through (0, -2) and has a slope of 0 is 
Step-by-step explanation:
We need to find the equation of the line that passes through (0, -2) and has a slope of 0?
The equation of line can be expressed in slope-intercept form 
where
- m is slope
- b is y-intercept
We need to find slope and y-intercept for the equation.
We are given slope = 0 so, m = 0
Now, y-intercept can be found using slope m=0 and point (0,-2)
So, we get y-intercept: b = -2
Now, the equation of the line having slope m=0 and y-intercept b=-2 is:
So, the equation of the line that passes through (0, -2) and has a slope of 0 is
Answer:
The bus fair is 50% increases.
Step-by-step explanation:
The percentage is the proportion of the relation to the whole.
Percentage increase is calculate as ratio of difference of original and new value to the original value. i.e.
∴ 
⇒ Percentage increase = 50%
Answer:
165
Step-by-step explanation:
Here we have to use the ratio.
Both earth and Pluto are in similar shapes.
To find the number of sphere the size of Pluto does it take to have the same volume, we need to divide the earth's volume by Pluto's volume.
= Earth's volume/Pluto's volume
= 4/3 π (6371)^3 ÷ 4/3 π (1161)^3
Cancelling out 4/3 π both in the numerator and in the denominator, we get
= (6371)^3 ÷ (1161)^3
= 258596602811 ÷ 1564936281
= 165.24
Approximately 165 spheres the size of Pluto to cover the earth volume.
