The transformations to function f(x) that results in function g(x) are described as follows:
5. Reflection over the x-axis, vertical stretch by a factor of 2.
6. Shift right of 6 units, shift up of 4 units.
7. The rule for g(x) after the transformation is given as follows:
[tex]g(x) = \sqrt[3]{-x + 7}[/tex]
What are the transformations to each function?For item 5, the functions are given as follows:
Parent function: [tex]f(x) = \sqrt{x}[/tex]Transformed function: [tex]g(x) = -2\sqrt{x}[/tex]The transformation is a multiplication by -2, which means that the function was:
Vertically stretched by a factor of 2, due to the multiplication by a number with absolute value of 2.Reflected over the x-axis, due to the multiplication by a negative number.For item 6, the functions are given as follows:
Parent function: [tex]f(x) = \sqrt[3]{x}[/tex]Transformed function: [tex]g(x) = \sqrt[3]{x - 6} + 4[/tex]Then the transformations are explained as follows:
Shift right of six units, due to the transformation x -> x - 6.Shift up of four units, due to the addition by 4.For item 7, the parent function is:
[tex]f(x) = \sqrt[3]{x}[/tex]
Then the transformations and their effects are given as follows:
Reflection over the y-axis: x -> -x.Translation 7 units right: -x -> -x + 7.Hence the function is:
[tex]g(x) = \sqrt[3]{-x + 7}[/tex]

Which equation represents a line with slope of -1/3 and y intercept of 5/3?
A. X-3y=5
B.3x-y=5
C.x+3y=5
D.3x+y=-5
The equation of line with slope is -1/3 and y intercept 5/3 is : x + 3y = 5.
What is equation of line?A straight line's general equation is y = mx + c, while m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Y = mx + c represents a equation of a straight line having gradient m and intercept c mostly on y-axis.In the form of a slope intercept, the line's equation looks like this:
y = mx + b
where
slope = m
y-intercept = b
Here given slope = -1/3
y-intercept at 5/3
As a result, the line's equation has a slope of -1 / 3.
Let's use the locations to determine the y-intercept 5/3.
y = mx + b
Here b = 5/3
By substituting ,
y = -1/3x + 5/3
Multiplying both sides by 3,
3y = -x + 5
3y + x = 5
= x + 3y = 5.
Therefore the equation of line is x + 3y = 5.

Suraj took a slice of pizza from the freezer and put it in the oven. The pizza's temperature (in degrees Celsius) as a function of time (in minutes) is graphed. How long was each increase by 4 degrees Celsius?
A.) 1/2
B.) 1 Minute
C.) 1/4
D.) 1/3
The time taken for the increase in temperature by 4 degrees Celsius is 1/2 minute.
Suraj took a slice of pizza from the freezer and put it in the oven. The pizza's temperature (in degrees Celsius) as a function of time (in minutes) is given in the form of a graph. The coordinates of the points through which the line passes are (2, 10) and (4.5, 30). We can find the slope of the straight line. If the coordinates of two points are (x1, y1) and (x2, y2), then the slope of the passing line is given as below.
m = (y2 - y1)/(x2 - x2)
m = (30 - 10)/(4.5 - 2)
m = 20/2.5
m = 8
This means there is an increase of 8 degrees in temperature in one minute. We need to calculate the time taken for a 4-degree increase in temperature.
m = Δy/Δx
8 = 4/Δx
Δx = 4/8 = 1/2
Hence, the increase in temperature by 4 degrees Celsius took half a minute.

(5x +27)°
(2x + 10)°
(4x + 2)°
The measure of angles of ( 5x + 27 )° , ( 2x + 10 )° and ( 4x + 2 )° are 102° , 40° and 62° respectively
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
Given data ,
The angles of the triangle ABC are
∠A = ( 2x + 10 )°
∠B = ( 4x + 2 )°
Let angle ∠C be y
The sum of ∠A + ∠B + ∠C = 180°
So ,
( 2x + 10 )° + ( 4x + 2 )° + y = 180° be equation (1)
Now , we can see that AD is a straight line and C is a point on the line AD
The total angle of C on the line AD is 180°
So , ( 5x + 27 )° + y = 180°
y = 180° - ( 5x + 27 )° be equation (2)
Substituting the value of equation (2) in equation (1) , we get
( 2x + 10 )° + ( 4x + 2 )° + 180° - ( 5x + 27 )° = 180°
On Simplifying , we get
( 2x + 10 )° + ( 4x + 2 )° - ( 5x + 27 )° = 0
( 2x + 4x - 5x ) + ( 10 + 2 - 27 ) = 0
x - 15 = 0
Adding 15 on both sides , we get
x = 15°
Substituting the value of x in the ∠A , ∠B and ∠C equation , we get
∠A = ( 2x + 10 )°
= 40°
∠B = ( 4x + 2 )°
= 62°
∠C = 180° - ( ∠A + ∠B )
= 180° - 102°
= 78°
Therefore , the angles of the triangle ABC are 40° , 62° and 78°
The measure of ( 5x + 27 )° is
= ( 5 x 15 + 27 )°
= 102°
Hence , the measure of angles of ( 5x + 27 )° , ( 2x + 10 )° and ( 4x + 2 )° are 102° , 40° and 62° respectively

For the given pair of intersecting lines, we find out that the value of x is 1 and the measure of the angle 1 is 169°.
From the figure we see that there are two lines intersecting each other.
We know,
Sum of all the angles formed = 360
We also know that
If there are a pair of two intersecting lines, then the vertically opposite angles are equal.
=> 20x+11 = 25x-14
=> 5x = 5
=> x = 1
Substituting the value of x in 20x+11 , we have
20*1 + 11 = 21°
Substituting the value of x in 25x-14 , we have
25*1 - 14 = 11°
It is also known to us that the sum of the adjacent angles of a pair of intersecting lines is equal to 180°. This implies that
11° + 1 = 180°
=> 1 = 180° - 11°
=> 1 = 169°

What are fractions?
Fractions are referred to as the components of a whole in mathematics. A single object or a collection of objects might be entire. When we cut a piece of cake in real life from the entire cake, the part represents the percent of the cake. The word "fraction" is derived from Latin. "Fractus" means "broken" in Latin. The fraction was expressed verbally in earlier times. It was afterward presented in numerical form.
A piece or sector of any quantity is another name for the fraction. It is indicated by the sign "/," such as a/b. For instance, in the fraction 2/4, the lower part represents the denominator, and the top part the numerator.
In the given question, we have:
