The equation is y+9=(1/5)(x-2).
What is a slope form?It is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. The three major forms of linear equations are point-slope form, standard form, and slope-intercept form. The equation of the slope form is y-y₁ = m(x - x₁)
The formula for the point-slope is,
y-y₁ = m(x - x₁)
y₁ is the y-coordinate of the point in the line, x₁ is the x-coordinate of the point in the line and m is the slope.
y₁ = -9
m = 1/5
x₁ = 2
Substituting the above values in the above equation, we get
y-(-9) = (1/5)(x-2)
By simplifying the above equation, we get
y+9 = (1/5)(x-2)
Therefore, the equation is y + 9 = (1/5)(x-2).

According to the question,
We have the following information:
The Parkview middle school football team will be playing in the state championship the coach free tickets that he would be distributing to his 52 football players to give to their friends and family and you would like to give each player at least three tickets.
So, we have the following expression:
1 player = 3 tickets
Now, we will use multiplication to find total number of tickets:
52 players = 52*3 tickets
52 players = 156 tickets

If one piece was 8 3/8 yards long, another 6 4/5 and the another 15 3/4 we need to compute the total length as shown as follows:
The total length was:
[tex]\text{Total length=8}\frac{3}{8}+6\frac{4}{5}+15\frac{3}{4}=30\frac{37}{40}=\frac{1237}{40}=30.92\text{ yards long}[/tex]Let f(x) = 4x² + 6.

g(x) = ____
g (x) = 4x² + 10 is the equation for g(x) in the simplest form.
What is a function?A special relationship where each input has a single output is called a function.
Given that, f(x) = 4x² + 6, the quadratic function g(x) is f(x) translated 3 units up.
The translation of a function f (x) in the Cartesian coordinate domain can be done by following the given guidelines:
Translation guidelines ;
Horizontal shifts
Right : f (x) → f (x - a)
Left : f (x) → f (x + a)
Vertical shifts
Up : f (x) → f (x) + b
Down : f (x) → f (x) - b
General shift (Horizontal and Vertical shift) is;
f (x) → f (x ± a) ± b
We will use the guidelines for Vertical shifts, where in this case the magnitude of b = 4.
f (x) = 4x² + 6
g (x) = f (x) + 4
g (x) = 4x² + 6 + 4
g (x) = 4x² + 10
Hence, the equation for g(x) in the simplest form is g (x) = 4x² + 10

In Exercises 1 and 2, solve the system using the elimination method.2. x + y - 2 = -22x – y += = 8-x + 2y + 2: = 10
(1,3,-7)
1) Let's write the following system of linear equations, and then solve them by the elimination method.
The first thing to do is to proceed with the elimination of one variable. In this case, let's chose to start with
x-6y+2z=5 x -2
2x-3y+z=4
3x+4y-z=-2
2x-12y+4z=10
2x-3y+z=4
3x+4y-z=-2
Adding these two equations:
2x-3y+z=4
-2x+12y-4z=-10
----------------------------------
9y -3z =-6
Now getting the other equations, let's eliminate another variable, in this case, "x"
-2x+12y-4z=-10 x 3
3x+4y-z=-2 x 2
Adding them
-6x +36y -12z=-30
6x+8y-2z=-4
----------------------------
0 44y -14z=-34
2) Now that we have a simpler system of two variables "y" and " z" let's operate them. Choosing a factor that we can multiply and cancel out the y variable, in this case, let's pick the Least Common Multiple between 9 and 44 = 396, so let's multiply them by
9y -3z = -6 x 44
44y-14z=-34 x -9
396y -132z = -264
-396y+126z=-306
----------------------------
6z =-42
z=-7
Plugging into the equation 9y -3z =-6
9y-3(-7)=-6
9y +21 =-6
9y=27
y=3
And for x
x-6y+2z=5
x-6(3)+2(-7)=5
x+18-14=5
x+4=5
x=1
3) So the solution for that system is (1, 3, -7).

Answer:
The lines are parallel, and therefore, never intersect.
What is the equation in slope -intercept form , of the line that is parallel to the guven line and passes through the point (0, 12
Answer:
A. y=-5+12
Step-by-step explanation:
It asks for slope intercept form which is y=mx+b. This matches the first option but not the last.
First you can rewrite the given equation (10x+2y=-2) in slope intercept form. That will give you y=-5x=1. (in the slope intercept form the number in front of the X is ur slope and the last number is ur Y intercept).
The question says that ur line is parallel to the given equation line. This means that they have the same slope. In your rewritten equation, y=-5x=1, the slope is -5 because it is in front of the X. A is the only option with -5 in the slope position.
All options are eliminated now but in case u want to know, when it tells you that the line passes through (0,12) that means the X intercept is 12. Because 0 is the x axis, and 12 is the Y. Y intercept just means the point where your line touches the Y axis.
Y intercept goes at the end and that also matches your first equation.

How to obtain the equations?The variable that represents the weight of the raspberries is given as follows:
x.
The variable that represents the weight of the blueberries is given as follows:
b.
She has 1/5 as many pounds of blueberries as raspberries, hence:
b = x/5.
If she picks 1 4/5 pounds more blueberries, she will have an equal weight of berries, hence:
b + 1 and 4/5 = x.
x/5 + 1 and 4/5 = x.

The concrete required to make the tank be 27.4122 m³.
Given, a concrete tank has an external diameter of 10 m and an internal height of 3 m. If the walls and bottom of the tank are 30 cm thick.
External diameter = 10 m

External radius = 5 m
Internal radius = 5 - 0.3 = 4.7 m
Volume = πh(e.r² - i.r²)
