Slope intercept form
y + 7 = 3(x + 4) Change all the double minuses to pluses.
y + 7 = 3x + 12 Remove the brackets.
y + 7 - 7 = 3x + 12-7 Subtract 7 from both sides
y = 3x + 5
Slope
Whatever number is in front of the x is the slope Answer: 3
y intercept
Whatever comes after the plus sign (or minus sign) is the y intercept. It is a single number. Answer: 5
x intercept.
This occurs when y = 0
0 = 3x + 5 Subtract 5 from both sides
-5 = 3x + 5 -5
-5 = 3x Divide by 3
-5/3 = 3x / 3
-5/3 = x
Answer: x_intercept = -5/3

Answers
[tex]-\frac{62}{9}[/tex]
Step-by-step explanation:The properties of equality state that you are allowed to perform operations on an equation as long as the operations are done equally on both sides.
Solving the Equation
First, rewrite the equation
[tex]-18x - 17 = 107[/tex]Next, apply the addition property of equality and add 17 to both sides
[tex]-18x=124[/tex]Finally, apply the division property of equality and divide both sides by -18

You buy 45 shares of evu confectioners at $63.12 apiece. unfortunately, the company falls on hard times and you end up selling the stock for $41.20 per share. how much money did you lose? a. $1,854.00 b. $986.40 c. $1,183.68 d. $2,840.40
Answers
Answer:
b is your answer to this question
The money lost due to a hard time for the company is $986.4.
Number of shares =45
Price per share =$63.12
So, the total cost of buying 45 shares = 45*63.12 = $2840.4
Total selling price when the company falls on hard times and you end up selling the stock for $41.20 per share = 41.20*45 = $1854
What is a loss?Mathematically, the loss is the difference between the cost price and the selling price.
Difference between the selling price and the cost price = 2840.4 - 1854
So, the difference between the selling price and the cost price = $986.4
Therefore, The money lost due to a hard time for the company is $986.4.

Step-by-step explanation:
to make a sketch of this graph. We're gonna make a table of values. I think that's probably our best route. So we'll do a couple negative values, but I'm gonna actually start at 08 to 0. Power zero. And I'm sorry. 80 parts one and one times negative. Three is negative. Three eight to the first. Power is eight and eight times negative. Three is negative. 24 8 X squared is 64 64 times negative. Three is on negative. 192. Okay, I think that's plenty. E to the negative. First power is 18 and 1/8 times negative. Three is negative. 3/8 and eight to the negative. To power is 1 64th times negative. Three is negative. 3 60 force. Okay, I think we can see where that's going. Is getting really close to zero. So as faras my graph here, I'm gonna focus on the fourth quadrant, I think. All right. So we got our X and y axis here. We're starting at 01 and to and we'll also do negative one. And negative two aren't horizontally, vertically. I do. I want to scale this whole the way to 1 92 I guess I will. Um, so whatever it is scaled by, maybe twenties. Yeah, let's do that. 20 40 60 8120 40 60 8200. So there's negative. 200? Um, negative. 1 80 Negative 1 60? Nope. That's not right. Because I scaled by twenties didn't. So this is actually negative. 1 60 This one's negative. 1 20 This one's negative. 80. And this is negative. 40. There we go. All right now a plot. These points to negative 1 92 is practically to 200 one. Negative. 24 is all the way over here. Zero negative three is practically on the X axis The way I have this, and same with those fractional values. They're practically on the X axis. So let's start almost parallel to the X axis because it's never actually touch step than its we don't ever. Slowly and then it starts going down rapidly, decreasing in value to the point where it's almost vertical, but it never will get vertical, so there's a decent sketch of y equals negative three times eight to the power of acts

Ann and Makiko like to swim laps at the community center pool.
They are swimming together today (day 1), but they are on different swim schedules. Ann swims every three days and Makiko swims every five days.
Question: How many times will they both swim at the pool on the same day
during the next ten weeks (including the first day)?
please explain process and show thinking in steps.
Answers
=========================================================
Explanation:
The LCM of 3 and 5 is 3*5 = 15.
Every 15 days, the two people will swim together on the same day.
Day 1 = first day swimming togetherDay 1+15 = Day 16 = second day swimming togetherDay 16+15 = Day 31 = third day swimming togetherAnd so on.
Keep this process going of adding on 15 to find this sequence
1, 16, 31, 46, 61, 76, ...
We stop the sequence once we either reach 70 or go over it because there are 7*10 = 70 days in ten weeks. This assumes we use a 7 day week rather than a 5 day week.
As shown in bold, there are 5 items smaller than 70. So the two people swam together a total of 5 times
-----------------
Alternatively, you can solve 15n+1 = 70 for n to get n = 4.6 which rounds down to n = 4 to represent the set {0,1,2,3,4} which has 5 items in it to represent the five times total they swim together.
n = 0 corresponds to day 15n+1 = 15(0)+1 = 1n = 1 corresponds to day 15n+1 = 15(1)+1 = 16and so on until reaching n = 4 corresponding to day 15(4)+1 = 61.
For a given input value n, the function h outputs a value mmm to satisfy the following equation.

Write a formula for h(n) in terms of n.
Answers
Considering the equation given, the formula for h(n) in terms of n is given by:
h(n) = -2n - 13
What is the equation?
The equation given is:
m + 1 = -2(n + 6).
We want to write m as a function of n, hence:
m + 1 = -2(n + 6).
m = -2n - 12 - 1
m = -2n - 13
Hence:
h(n) = -2n - 13

Assuming that a line segment with a length of 12 units is formed by points A and B.
In addition, Point A is situated at (5,-4)

Is (3, -5) a solution to this system of equations?
y = -1/3x - 4
y = -2x + 1
Yes or No
Answers
Answer: Yes
Step-by-step explanation:
Solve the system of equations by setting the two substituting the first y equation in for the second and getting: -1/3x - 4 = -2x + 1.
Now, add 2x to the left side to cancel it from the right and add 4 to the right side to cancel if from the left to get: (5/3)x = 5
Solve for x to get 3.
Plug x into the second equation (could be either equation though) and get: y = -2(3) = 1 = -5.
Thus, (3,-5) is a solution :)

Step-by-step explanation:
First we can square both sides to remove the square roots:
[tex](\sqrt{x+7})^{2} +(\sqrt{x+2})^{2} = (\sqrt{6x+13})^{2}[/tex]
Simplify:
[tex]x+7+x+2=6x+13[/tex]
Now we simplify further:
[tex]2x+9=6x+13[/tex]
Now we subtract 13 from both sides:
[tex]2x+9-13=6x+13-13[/tex]
Simplify:
[tex]2x-4=6x[/tex]
Subtract 2x from both sides:
[tex]2x-4-2x=6x-2x[/tex]
Simplify:
[tex]-4=4x[/tex]
Divide both sides by 4:
