How to determine the solution to the systemFrom the question, we have the following equations that can be used in our computation:
y = -3(x - 1)
y = -3x - 1
Also, we have:
The lines are parallel to each other.
As a general rule:
Parallel lines are lines that do not intersect and they have the same slope
Because the lines do not intersect, it means that the system do not have any solution

What is graph of a function?
A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.
There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.
Graph of a function f(x) is the collection of all points of the form (x, f(x)).

The difference between the roots of the quadratic equation x^2+x+c=0 is 6. Find c.
Answer:
c=-35/4
Step-by-step explanation:
For this, we would use Vieta's theorem, which states the roots of the equation added together would equal -b/a, x₁ + x₂ = -b/a
Lets create a system with this:
x₁ - x₂ = 6 (This is given from the problem)
x₁ + x₂ = -b/a or -1/1, plugging in the values from your equation
next, we would add these systems together
x₁ + x₂ + (x₁ - x₂) = 6 + (-1)
x₁ + x₁ = 5
2x₁ = 5
x₁ = 2.5
If we plug x₁ back in, we get:
2.5 - x₂ = 6
-x₂ = 3.5
x₂ = -3.5
Now that we have the roots, we can use Vieta's theorem again to say
x₁ * x₂ = c/a
Plugging this in, we get:
2.5 * -3.5 = c/a
Lets change things to fractions to make things easier
5/2 * -7/2 = c/a
Plugging in a, we get
-35/4 = c/1
-35 = 4c
c = -35/4
Hope this helps!

Function h(x) = -1Function g(x) = -1Function f(x) = 2How to determine the y-intercepts?The complete question is added at the end of this solution as an attachment
As a general rule, the y-intercept is the point in an equation or a function where x = 0
Using the above as a guide, we have the following:
The y-intercept of function h(x) = -1The y-intercept of function f(x) = 2For the function g(x), we have
g(x) = abˣ
Using the given points (1, -2) and the growth factor of 2, we have
g(x) = a(2)ˣ
This means that
a(2)¹ = -2
So, we have
2a = -2
a = -1
So, the equation is
g(x) = -1(2)ˣ
Set x = 0
g(0) = -1(2)⁰
g(0) = -1
So, the y-intercept of function g(x) = -1

what happens to the mean for a trait in a population during directional selection what is being selected for?
When a population is subjected to directional selection over time, the traits that are selected for will remain stable while the traits that are selected against will disappear.
Evolution is the study of how populations change over time. Most traits have multiple genes controlling their structure, function, appearance, and other characteristics. Single genes only very infrequently control a trait.
As a result, most traits have a tendency to be continuous in nature and to have a wide range of values. One side of these values will be picked against during directional selection, while the other side will be selected in favor of. Look at the illustration of a lemur's fur color below.

Since the rectangle's shorter side is half as long as its longer side, its top left vertex is (0,a).
What is coordinate?A pair of numbers that use the horizontal and vertical separations from the two reference axes to define a point's location on a coordinate plane. typically expressed by the x-value and y-value pair (x,y). You do the reverse to determine a point's coordinates in a coordinate system. Start at the point, then move up or down a vertical line until you reach the x-axis. Your x-coordinate is shown there. To find the y-coordinate, repeat the previous step while adhering to a horizontal line.

Given the points A(-2, -1) and B(-5, 3), answer the following questions.
a) Find the length of the segment.
b) Find the slope of the line segment.
c) Write the equation of the line that contains the two points.
Answer:
a) 5
b) -4/3
c) y = -4/3x - 11/3
Step-by-step explanation:
The length of the segment means the length in between two points. Use 2 dimensional distance formula.
[tex]d = \sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2 }[/tex]
Plug in your points.
x value is the first point in the set, the horizontal measure in units.
y value is the second point in the set, the vertical measure in units.
x values of 2 points: -2, -5
y values of 2 points: -1, 3
[tex]d = \sqrt{(-5--2)^2 + (3--1)^2 }[/tex]
A negative value subtracted by another negative value is the first negative value plus the inverse of the second negative value.
For example,
-5 - -6 = -5 + 6 = 1
Simplify.
[tex]d = \sqrt{(-3)^2 + (4)^2 }[/tex]
[tex]d = \sqrt{9 + 16}[/tex]
[tex]d = \sqrt{25}[/tex]
5
Square root of 25 is 5 because 5^2, which is 5 x 5 is 25.
The slope is how much the y-value changes when the x-value increases by 1.
To calculate this, plug your points into the slope formula.
[tex]Slope = \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\frac{3--1}{-5--2}[/tex]
[tex]\frac{4}{-3}[/tex]
-4/3
I'm going to assume that the problem is asking you to write it in the form of y=mx+b, or slope-intercept form, a way of easily graphing a line. If it is asking you to express it in another way like Standard or Point-Slope Form, comment and I'll change it.
y = mx+b
m = slope
b = y-intercept, or the y-value of when the x-value is 0 on a line
y and x stays as variables if you want to graph it and for generally answering problems.
So, if x = 0, we can plug it into what we currently know.
We know the points: (-2,-1) or (-5,3)
Plug in either set of points into the slope-intercept equation.
I'll use -2,-1 but you can use either.
-1 = (-4/3) (-2) + b
Because we're solving for when x is 0, replace -2 for 0.
-1 = 8/3 + b
Subtract 8/3 on both sides.
-1 - 8/3 = 8/3 - 8/3 + b
-1 - 8/3 = b
b = -11/3
Now, the equation is:
y = -4/3x - 11/3
This is the beauty of the forms of linear equations. You can plug in any points to solve for the full set of points. You can convert any form of the linear equation to another form.
