Point slope formula is
y-y1=m(x-x1)
where m is slope
m=1/4 is given
points are (0,-4)
y+4=1/4(x-0)
y+4=1/4x
y=1/4X-4
Answer: Sorry i only speak english
Step-by-step explanation:
So he has 4 hrs on his mp3 player...for which jazz makes up 1/6 of it..
so we need 1/6 of 4 hrs...." of " means multiply
1/6 * 4 = 4/6 = 2/3 of an hr <==
Answer:
RQ = RS = 3
Step-by-step explanation:
Since RQ and RS are radii of the circle then they are congruent
let RQ and RS be x , then
Using Pythagoras' identity in right triangle QRS
x² + x² = (3
)²
2x² = 18 ( divide both sides by 2 )
x² = 9 ( take the square root of both sides )
x = 
= 3
Thus RQ = RS = 3

Answer:</h2>
D. The Earth's surface would be much colder than it is.
<h3>
Step-by-step explanation:</h3>
This is because warm temperatures and high levels of atmospheric carbon dioxide happen at about the same time. So if atmospheric carbon dioxide concentrations double warm up by between 2 and 4.5 degrees Celsius. On the other hand, water vapor promotes, as the greatest contributor, to the Earth’s greenhouse effect. In this way, if carbon dioxide, methane, and water vapor were not in the atmosphere, then it's obvious that the Earth's surface would be much colder than it is.
