Step-by-step explanation:
gradient means slope.
the slope is anyways the factor a of x on the slope-intercept form
y = ax + b
and in the point-slope form
y - y1 = a(x - x1)
"a" is as mentioned the slope. b is the y-intercept (the y- value when x = 0).
(x1, y1) is a point on the line.
a)
y = (1/2)×x - 2
b)
y - 2 = 3(x - -2) = 3(x + 2) = 3x + 6
y = 3x + 8
c)
remember, the slope is defined as ratio (y coordinate change / x coordinate change) when going from one point on the line to another.
so, let's go from (1, -2) to (-2, 1)
x changes by -3 (from 1 to -2)
y charges by +3 (from -2 to 1)
the slope is +3/-3 = -1/1 = -1
so, we pick one point, e.g. (1, -2), and the line is
y - -2 = -(x - 1) = -x + 1
y + 2 = -x + 1
y = -x - 1
d)
x = -1
this is a vertical line (parallel to the y-axis) representing all points on the grid for which x = -1.
the slope is undefined, as it is y/0 (because x never changes at all). and there is no y-intercept, as x can never be 0, and the line is parallel to the y-axis, so, there cannot be any intersection point.

[tex]\textsf{b) \quad $y=3x+8$}[/tex]
[tex]\textsf{c) \quad $y=-x-1$}[/tex]
[tex]\textsf{d) \quad $x=-1$}[/tex]
Step-by-step explanation:
Part (a)Slope-intercept form of a linear equation:
[tex]y=mx+b[/tex]
where:
m is the slope.b is the y-intercept.Given values:
Slope = ¹/₂y-intercept = -2Substitute the given values into the formula to create the equation of the line:
[tex]\implies y=\dfrac{1}{2}x-2[/tex]
---------------------------------------------------------------------------
Part (b)Point-slope form of a linear equation:
[tex]y-y_1=m(x-x_1)[/tex]
where:
m is the slope.(x₁, y₁) is a point on the line.Given:
Slope = 3(x₁, y₁) = (-2, 2)Substitute the given values into the formula to create the equation of the line:
[tex]\implies y-2=3(x-(-2))[/tex]
[tex]\implies y-2=3(x+2)[/tex]
[tex]\implies y-2=3x+6[/tex]
[tex]\implies y=3x+8[/tex]
---------------------------------------------------------------------------
Part (c)Slope formula:
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are points on the line.
Given points:
(x₁, y₁) = (1, -2)(x₂, y₂) = (-2, 1)Substitute the points into the slope formula to calculate the slope of the line:
[tex]\implies m=\dfrac{1-(-2)}{-2-1}=\dfrac{3}{-3}=-1[/tex]
Substitute the found slope and one of the points into the point-slope formula to create the equation of the line:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-(-2)=-1(x-1)[/tex]
[tex]\implies y+2=-x+1[/tex]
[tex]\implies y=-x-1[/tex]
---------------------------------------------------------------------------
Part (d)If the line is parallel to the y-axis, it is a vertical line.
The equation of a vertical line is x = c.
Therefore, as the line intersects the x-axis at -1, the equation of the line is:

Figure 3 can also be created by transforming figure 1 with a sequence of two transformations. Which statement describes a possible sequence of transformations that transforms figure 1 into figure 3?
A. a rotation 180 degrees clockwise about the origin, followed by translation 2 units to the left.
B. a rotation 90 degrees clockwise about the origin, followed by a reflection across the x-axis.
C. a rotation 180 degrees clockwise about the origin, followed by a reflection across the y-axis.
D. a rotation 90 degrees clockwise about the origin, followed by a translation 3 units to the right.
the correct answer is A. Option A describes a rotation of 180 degrees clockwise, which would result in figure 1 being upside down, and then a translation of 2 units to the left.
What is triangle?
A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.
To transform figure 1 into figure 3, we need to apply two transformations. We can eliminate option B because a rotation of 90 degrees followed by a reflection across the x-axis would transform figure 1 into a mirror image of figure 2, not figure 3.
Option A describes a rotation of 180 degrees clockwise, which would result in figure 1 being upside down, and then a translation of 2 units to the left. This would transform figure 1 into figure 3, so option A is a possible sequence of transformations.
Option C describes a rotation of 180 degrees clockwise followed by a reflection across the y-axis. This would transform figure 1 into a mirror image of figure 2, not figure 3.
Option D describes a rotation of 90 degrees clockwise followed by a translation of 3 units to the right. This would transform figure 1 into a position that is similar to figure 3, but the orientation of the triangle would be different.
Therefore, the correct answer is A.

If 5 books of equal weight, weigh 1.755 kilograms, how many books will weigh 1.404 kilograms?
If 5 books of equal weight, weigh 1.755 kilograms, then the number of books will weight 1.404 kilogram is 4 books
The 5 books are equal weights
The weight of 5 books = 1.755 kilograms
Then the weight of one book = The weight of 5 books / 5
Substitute the values in the equation
The weight of one book = 1.755/5
= 0.351 kilograms
To find the number of books we have to use division again
The number of books will weight 1.404 kilograms = 1.404 / The weight of one book
=1.404/0.351
= 4 books

The probability that an adult is actively looking for a job is 0.18. The probability of an adult being unemployed and actively looking for a job is 0.04. What is the probability of an adult being unemployed given that they are actively looking for a job?
The probability of an adult being unemployed given that they are actively looking for a job is 0.22.
How to calculate the probability?It should be noted that probability gas to do with the likelihood that something will occur.
Remember the multiplication rule for conditional probability:
P(B AND A)=P(B|A)P(A)
Rearranging, we see thatP(B|A)=P(B AND A)P(A)
So if we think of A as being the event that an adult is actively looking for a job and B as the event that an adult is unemployed, then we can plug in the known information to find
P(B|A)=0.04 + 0.18

f (x + h) - f (x) = h² + 2xh + 6h
f (x + h) - f (x) / h = h + 2x + 6
What is substitution method?
Find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The value of the function is;
f (x) = x² + 6x + 7
Now, Find the given values of f (x + h) , f (x + h) - f (x) and f (x + h) - f (x) / h by substitution method.
The value of the function is;
f (x) = x² + 6x + 7
Substitute x = x + h;
The value of the function is;
f (x + h) = (x + h)² + 6(x + h) + 7
= x² + 2xh + h² + 6x + 6h + 7
Thus, The value of f (x + h) = x² + 2xh + h² + 6x + 6h + 7.
Now,
f (x + h) - f (x) = (x² + 2xh + h² + 6x + 6h + 7) - (x² + 6x + 7)
= x² + 2xh + h² + 6x + 6h + 7 - x² - 6x - 7
= h² + 2xh + 6h
Thus, The value of f (x + h) - f (x) = h² + 2xh + 6h.
Now,
f (x + h) - f (x) / h = h² + 2xh + 6h / h
= h (h + 2x + 6) / h
= h + 2x + 6
Thus, The value of f (x + h) - f (x) / h = h + 2x + 6.
Therefore, The values are;
f (x + h) = x² + 2xh + h² + 6x + 6h + 7
f (x + h) - f (x) = h² + 2xh + 6h
f (x + h) - f (x) / h = h + 2x + 6

The rule of (x, y) → (-x, y), which is reflection over y-axis.
Given that, ΔABC maps to triangle ΔA'B'C'.
What is the reflection on y-axis?When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).
The coordinate points of ΔABC are A(-4, 3), B(-3, -3) and C(1, 2) and the coordinate points of ΔA'B'C' are A'(4, 3), B'(3, -3) and C'(-1, 2).
Here, A(-4, 3) → A'(4, 3), x-coordinate is negated and y-coordinate remains same.
Similarly, B(-3, -3) → B'(3, -3) and C(1, 2) → C'(-1, 2) follows the same pattern.
From this, it is clear that the coordinates of triangle ABC is reflected on y-axis.

For the given function, it is found that:
The extreme points are given by: (3,3) and (1,7).The inflection point is: (1,7).What are the extreme points of a function?The extreme points of a function happen at the values for x for which the first derivative is zero, that is:
y' = 0.
In this problem, the function is:
y = x³ - 6x² + 9x.
Hence the first derivative is:
3x² - 12x + 9.
The extreme values of x are:
3x² - 12x + 9 = 0.
3(x² - 4x + 3) = 0
x² - 4x + 3 = 0
(x - 3)(x - 1) = 0.
Then:
x - 3 = 0 -> x = 3.x - 1 = 0 -> x = 1.The numeric value of the function at these points is:
x = 3: y = 3³ - 6(3)² + 9(3) + 3 = 3.x = 1: y = 1³ - 6(1)² + 9(1) + 3 = 7.Hence the points are:
(3,3) and (1,7).
What are the inflection points of a function?The extreme points of a function happen at the values for x for which the second derivative is zero, that is:
y'' = 0.
For this problem, the second derivative is given by:
y'' = 6x - 12.
Hence the x-coordinate of the inflection point is:
6x - 12 = 0
6x = 12
x = 2.
The numeric value at x = 2 is:
2³ - 6(2)² + 9(2) + 3 = 5.

In desperate need of help with my college algebra problem
To find the nth degree of polynomial function f(x) = x^4 - 4x^3 + 27x^2 -46x +60
What is Function?
Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
For polynomial with real coefficients, the complex zeros come with conjugates so 2+4i must come with 2-4i , then for 4th degree polynomial
f(x) =a (x+1)(x-3)(x-2-4i)(x-2+4i). With given f(1)=-68
a(1+1)(1-3)(1-2-4i)(1-2+4i)= -68.
By this we can find a
a (2)(-2)(-1-4i)(-1+4i) = -68
a(-4)(1+4i-4i-16i^2) = -68
a(-4)(1+16) = -68
a(-4)(17) = -68
a(-68) = -68
a = 1
Now, solving
f(x) =(x+1)(x-3)(x-2-4i)(x-2+4i)
f(x) = (x+1)(x-3)(x^2 - 2x + 20)
f(x) = (x^2 - 2x - 3)(x^2 - 2x + 20)
f(x) = x^4 - 2x^3 + 20x^2 - 2x^3 + 4x^2 - 40x + 3x - 6x + 60
f(x) = x^4 - 4x^3 + 27x^2 -46x +60
Hence, the for 4th degree polynomial is f(x) = x^4 - 4x^3 + 27x^2 -46x +60
