Answer:
[tex]\boxed {m = -\frac{5}{7}}[/tex]
Step-by-step explanation:
Use the Slope Formula to determine the slope of two given points:
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
First Point: [tex](x_{1} , y_{1})[/tex]
Second Point: [tex](x_{2}, y_{2})[/tex]
-Substitute both points:
First Point: [tex](5, 11)[/tex]
Second Point: [tex](19, -1)[/tex]
[tex]m = \frac{-1 - 11}{19 - 5}[/tex]
-Solve for the slope:
[tex]m = \frac{-1 - 11}{19 - 5}[/tex]
[tex]m = \frac{-10}{14}[/tex]
[tex]\boxed {m = -\frac{5}{7}}[/tex]
Therefore, the slope is [tex]-\frac{5}{7}[/tex]

The snow is now 52 inches deep. If this was a 77%
decrease, what was the initial depth
Answer:
29.3785310734 is the exact answer but you can estimate
Step-by-step explanation:
Let’s say the initial depth was 100%.
A 77% decrease would mean that 77% of the 100% was added to the hole so then it final result would be 177% of the initial hole which is also 52 as given. 177% is the same as 1.77 so we would divide 52 by 1.77 to get that x = 29.3785310734. Still confusing? Just look here:

Jamie was working on his math homework with his friend, Kent. Jamie looked at the following problem.
−9.5 − (−8)− 6.5
He told Kent that he did not know how to subtract negative numbers. Kent said that he knew how to solve the problem using only addition. What did Kent mean by that? Explain.
Answer:
When subtracting a negative number, the two subtractions signs cancel out to be a positive.
Step-by-step explanation:
When subtracting a negative number, the two subtractions signs cancel out to be a positive.So, -9.5 - (-8) - 6.5 = -9.5 + 8 - 6.5I hope this helps!

4 < x < 9 x is an interger, write down all the possible values of x
Answer:
The possibel values of x is 5, 6, 7, 8.
Step-by-step explanation:
Integer is a positive or negative whole number.
In this case, x must be positive and it have to be greater than 4 but smaller than 9 so the possible values will be 5, 6, 7 and 8.
It says [tex]x[/tex] is greater than [tex]4[/tex] and it is less than [tex]9[/tex]
The first value which is greater than [tex]4[/tex] is [tex]5[/tex] and the value which is less than [tex]9[/tex] is [tex]8[/tex]. So the answer would be all integers from [tex]5[/tex] to [tex]8[/tex] (inclusive)
[tex]5, 6, 7, 8[/tex] would be the answer! :D
A parabola can be drawn given a focus of (5, -7) and a directrix of x=1. Write the equation of the parabola in any form.
Answer:
x = 1/8(y^2 + 14y + 73)
Step-by-step explanation:
Take any point on the curve (x, y). This is a parabola that opens to the right and contains terms in x and y^2.
The distance of this point from the focus = its distance from the directrix, so:
sqrt [( x - 5)^2 + (y + 7)^2) = (x - 1)
Squaring both sides:
(x - 5)^2 + (y + 7)^2 = (x - 1)^2
x^2 -10x + 25 + y^2 + 14y + 49 = x^2 - 2x + 1
y^2 + 14y + 73 = 8x
x = 1/8(y^2 + 14y + 73)

Determine whether the following relation represents a function.
{(-9,8), (-2,1), (-7,5), (-4,3), (-8,2)}
Answer:
yes
Step-by-step explanation:
Each input value only goes to one output value so the relation is a function
The domain isn't repetitive so it's function.
Domain of Relation is {-9,-2,-7,-5,-4,-8}. There are no same domains or repetitive so It's a function.
