Answer:
<h2>y + 1 = 5(x - 1)</h2>
Step-by-step explanation:
The slope-intercept form:

m - slope
b - y-intercept
Parallel lines have the same slope.
We have y = 5x → m = 5.
The point-slope form:

We have the slope m = 5 and the point (1, -1). Substitute:

Answer:
2/3
Step-by-step explanation:
To find the probability, you first have to add up the total number of marbles in the bag.
3+4+9+5=21
Next you find the probability of getting a yellow:
9/21
Then you find the probability of getting a green:
5/21
And since the problem says "yellow <em>or</em> green" we will add the two together
9/21 + 5/21 = 14/21 = 2/3
Number 7 I believe the answer is 74.
Answer:
The longer part is <u>45 cm</u> long and the shorter part is <u>25 cm</u> long.
Step-by-step explanation:
Given:
A 70 cm long stick is cut into two parts in such a way that the longer part is 20 cm longer than the shorter part.
Now, to find the length of each part of the stick.
Let the shorter part be 
So, the longer part is 
Total length of the stick = 70 cm.
Now, to get the length of each part we solve an equation:

<em>The length of the shorter part is 25 cm.</em>
Now, substituting the value of
:

<em>The length of longer part is 45 cm.</em>
Therefore, the longer part is 45 cm long and the shorter part is 25 cm long.
