What is the slope and y-intercept of the equation 3x -y=3
Answer:
Slope = 3
Y Intercept = 3
Step-by-step explanation:
3x - y = 3
(subtract 3x from both sides - we have to get y by itself)
-y = -3x - 3
(divide by -1 from both side - we need to make y positive)
y = 3x + 3

A. (2, 0) B. (-2, 0) C. (0, 2) D. (0, -2
Answer:
The answer is B. (-2, 0)
Step-by-step explanation:
x= 2 ⋅ cos(π) = −2

The rectangular coordinates is (-2 , 0) , Option B is the correct answer.
What is the equation of conversion of Polar Coordinates to Rectangular Coordinates ?The equation for a polar point ( r, [tex]\rm \theta[/tex]) is
x = rcos [tex]\rm \theta[/tex]
y =r sin [tex]\rm \theta[/tex]
where (x , y) are rectangular coordinates.
The polar coordinate given is ( 2 , π)
r = 2
[tex]\rm \theta[/tex] = π
so
x = 2 cos π
x = 2 * (-1)
x = -2
y = 2 sin π
y = 2 *0
y = 0
Therefore the rectangular coordinates is (-2 , 0) , Option B is the correct answer.

What’s the distance 3 1/4 and -15
Answer:
18 1/4
Step-by-step explanation:
The easiest way to do this is to start at 0 and go 3 1/4 units to your right.
Then start at 0 and go -15 units to your left. So far I have not used a formula because I want you to see intuitively what the answer is. Then we'll do it with a formula.
The total distance is 3 1/4 + 15 = 18 1/4. Purists will hate the way I've done it, but beginners should understand what they are doing.
A formula would look like this
distanace = sqrt( x2 - x1 )^2 + (y2 - y1)^2 )
distance = sqrt( (3 1/4 - - 15)^2 + (4 - 4)^2 )
distance = sqrt( (18 1/4 )^2 + 0)
distance = 18 1/4

The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially. How many grams of the substance are left after 300 years?
a) 5039.684g
b) 2828.427g
c) 3000g
d) 2000g
Answer:
There are 2,000 grams left after 300 years.
Step-by-step explanation:
Giving the following information:
The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.
First, we need to calculate the reduction of the substance each year:
Yearly reduction= 8,000/400= 20 grams per year
Now, for 300 years:
300 year reduction= 20*300= 6,000
There are 2,000 grams left after 300 years.
