Answers
First, we transform the coordinates of the vertices of P 270° anticlockwise.
The 270° anticlockwise transformation rule, T, is defined as:
[tex]T\colon(x,y)\to(y,-x)_{}[/tex]Therefore,
[tex]T(-1,2)=(2,1)[/tex][tex]\begin{gathered} T(-1,4)=(4,1) \\ T(-4,2)=(2,4) \\ T(-4,4)=(4,4) \end{gathered}[/tex]Let the resultant shape be named P'
Hence,
P': (2,1), (4,1) (2,4) (4,4)
Next
We translate the resultant shape downwards by 6 units.
The transformation rule, S, for moving downwards by 6 units is given by:
[tex]S\colon(x,y)\to(x,y-6)_{}[/tex]Therefore,
[tex]S(2,1)=(2,1-6)=(2,-5)[/tex][tex]\begin{gathered} S(4,1)=(4,1-6)=(4,-5) \\ S(2,4)=(2,4-6)=(2,-2) \\ S(4,4)=(4,4-6)=(4,-2) \end{gathered}[/tex]Hence, the image of S on P' is : (2,-2) (2,-5) (4,-2) (4,-5)

Answers
November savings = 45
Explanation:
Amount saved in June = 20
Amount saved in July = 25
Amount saved in August = 30
From the above, there is an increament of 5 as the month increases:
30-25 = 25-20 = 5
September = August savings + increament
September saving = 30 + 5 = 35
October = September savings + increament
October = 35 + 5 = 40
November = October savings + increament
November savings = 40 + 5
November savings = 45

What is a graph?A graph can be defined as a type of chart that's commonly used for the graphical representation of data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
In Mathematics, the x-intercept of any graph simply refers to the point at which the graph of a function crosses the x-axis and the value of "y" is equal to zero (0).
By critically observing the graph which models the data of this function, we can reasonably and logically deduce that the value of x when the function, f(x) = -3 is is equal to -2.

We have a total of 10 cards.
From these 10 cards, three cards are number 4, so the probability of choosing a number 4 is P = 3/10.
Calculating the probability for each option, we have:
A. Odd number
There are 6 odd numbers among the cards, so the probability is P = 6/10
B. Prime number
There are 3 prime numbers among the cards, so the probability is P = 3/10
C. Another even number
There are 4 even numbers among the cards, so the probability is P = 4/10
D. An odd number less than 7.
There are 3 odd numbers less than 7, so the probability is P = 3/10
The bigger probability is for an odd number, therefore the correct option is A.

Answers
Assume "h" = number of hours traveled
Helen's speed = 6km per hour and is 4km advanced than Paris
Paris' speed = 8km per hour
Therefore, we can form the following equations:
a. Helen's distance traveled = 4km + 6km (h) = 4 + 6h
b. Paris' distance traveled = 8km (h) = 8h
For us to determine how long will Paris be able to catch Helen, we'll have to assume they have traveled the same distance. In this case:
Helen's distance traveled = Paris' distance traveled
[tex]\begin{gathered} 4+6h=8h \\ \text{Subtrach 6h on both sides of the equation.} \\ 4+6h-6h=8h-6h \\ 4=2h \\ \text{Divide two on both sides.} \\ \frac{4}{2}=\frac{2h}{2} \\ 2=h \end{gathered}[/tex]Therefore, it will take 2 hours for Paris to catch up with Helen which is at 16km.

Find the equation for the tangent to the curve of f at the point:f(x) = (3x+1)² , x = -1
Answers
The eqaution of the tangent at the point x = -1 is:
[tex]y=-12x-8[/tex]To solve this, first, we need to find the value of y when x = -1:
[tex]f(-1)=(3\cdot(-1)+1)^2=(-3+1)^2=(-2)^2=4[/tex]Then we want to find the equation of the tangent at the point (-1, 4)
The next step is to find the derivative of the equation, because the derivative thell us the slope of the tangent line at a certain point:
[tex]\begin{gathered} f(x)=(3x+1)^2 \\ f^{\prime}(x)=2(3x+1)\cdot3=6(3x+1)=18x+6 \\ \\ f^{\prime}(x)=18x+6 \end{gathered}[/tex]Now that we have the derivative, let's calculate the slope of the tangent like in the point (-1, 4). To do this, we evaluate the derivative in x = -1:
[tex]f^{\prime}(-1)=18\cdot(-1)+6=-18+6=-12[/tex]The slope of the tangent line is -12.
Now we have all the necessary things to construct the equation of a line: we have the slope (-12) and a point (-1, 4).
The slope-point form of a line is:
[tex]\begin{gathered} y=m(x-x_0)+y_0 \\ \end{gathered}[/tex]Where m is the slope and x0, y0 are the x and y coordinates of a point
Then:
[tex]\begin{gathered} \begin{cases}m=-12 \\ x_0=-1 \\ y_0=4\end{cases} \\ y=-12(x-(-1))+4=-12\mleft(x+1\mright)+4=-12x-12+4=-12x-8 \end{gathered}[/tex]And that's the equation of the line y = -12x - 8

Write and solve an inequality that represents how many pounds the parents can add tothe shipment without having to pay additional shipping costs
Answers
Answer
The inequality equation is
(9 + x) ≤ 15
The solution is
x ≤ 6 pounds
The number of pounds that the parents can add to the shipment without having to pay additional shipping costs is less than or equal to 6 pounds.
Step-by-step Explanation
The question wants us to write and solve an inequality that represents how many pounds the parents can add to the shipment without having to pay additional shipping costs.
The towels needed by the student already weigh 9 pounds.
The maximum weight of shipment that is allowable for a payment of $45 is 15 pounds.
Let the additional weight that the parents can add to the shipment without having to pay additional shipping costs be x.
Since the maximum weight allowable is 15 pounds, the 9 pounds already on ground plus the additional x pounds must not exceed 15 pounds. That is, that total weight must always be less than or equal to 15 pounds.
Mathematically,
(9 + x) ≤ 15
This is the inequality equation. We can now solve this
(9 + x) ≤ 15
Subtract 9 from both sides
(9 + x) - 9 ≤ 15 - 9
9 + x - 9 ≤ 6
x ≤ 6
Hence, the number of pounds that the parents can add to the shipment without having to pay additional shipping costs is less than or equal to 6 pounds.

Ratios and fractions are the main bases on which proportion is explained. Two ratios are equal when they are expressed as a fraction in the form of a/b, ratio a:b, and then a proportion.
The industrial machine made a total of 1629 cans of diet soda which is 6 times as much regular soda in 46 minutes.
Then, the total number of regular sodas made will be:
R = 4 × Total number of diet soda
R = 4 × 1629 cans
R = 6516 cans
The regular sodas were packed in 3 shipping boxes with each having the same number of soda cans.
Therefore, the number of cans of regular sodas in each box will be:
N = 6516/3
N = 2172 cans
There are 2172 cans of regular sodas in each shipping box.

If we drop a ball from 60 inches height it bounces 42 iches.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
The height that a ball bounces varies directly as the height from which it was dropped.
A tennis ball dropped from 17 inches bounces 11.9 inches.
We need to find from which height if we drop a ball bounces 42 iches.
Let us consider x as the unknown height
Let us form a equation by the given data
17/11.9=x/42
Apply cross multiplication
17×42=11.9x
714=11.9x
Divide both sides by 11.9
60=x
Hence if we drop a ball from 60 inches height it bounces 42 inches.

Plot the given parabola on the axes. Plot the roots, the vertex and two other points.
Answers
Solution
Step 1:
The first two points are the roots of the parabola.
To get the roots of the parabola, equate y = 0
[tex]\begin{gathered} \text{y = x}^2\text{ + 2x - 35} \\ x^2\text{ + 2x - 35 = 0} \\ x^2\text{ + 7x - 5x - 35 = 0} \\ x(x\text{ + 7)-5(x + 7) = 0} \\ (x\text{ + 7)(x - 5) = 0} \\ x\text{ = -7 , x = 5} \\ \text{The parabola intercept x-axis at (-7, 0) and (5 , 0)} \end{gathered}[/tex]Step 2:
Find the y-intercept.
To find the y-intercept, plug x = 0
[tex]\begin{gathered} \text{y = x}^2\text{ + 2x - 35} \\ y=0^2\text{ + 2}\times0\text{ - 35} \\ y\text{ = -35} \\ y-\text{intercept is (0 , -35)} \end{gathered}[/tex]Step 3:
Find the vertex
[tex]\begin{gathered} \text{The vertex is (}\frac{-b}{2a}\text{ , y)} \\ b\text{ = 2, a = 1} \\ x\text{ = }\frac{-b}{2a} \\ x\text{ = }\frac{-2}{2\times1} \\ x\text{ = }\frac{-2}{2} \\ x\text{ = -1} \\ y=(-1)^2\text{ + 2(-1) - 35} \\ y\text{ = 1 - 2 - 35} \\ y\text{ = -36} \\ \text{Vertex = (-1, -36)} \end{gathered}[/tex]Final answer
All the five points are:
Roots (x-intercept) = (-7, 0) , (5 , 0)
y-intercept = (0, -35)
vertex = (-1, -36)
Other point = (-5, -20)

Use properties to rewrite the given equation. Which equations have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p? Select two options.
Answers
The equations that have the same solutions as 2.3p – 10.1 = 6.5p – 4 – 0.01p are as follows:
2.3p – 10.1 = 6.49p - 4230p - 1010 = 650p - 400 - pHow to find same solution equation?Systems of equations that have the same solution are called equivalent systems.
Therefore, the equation that have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p can be calculated as follows:
Hence, let's find the solution of this :
2.3p – 10.1 = 6.5p – 4 – 0.01p
Simplifying the above equation by collecting like terms gives;
2.3p – 10.1 = 6.5p – 4 – 0.01p
2.3p – 10.1 = 6.5p – 0.01p - 4
Therefore, one of the equivalent solution is as follows:
2.3p – 10.1 = 6.49p - 4
Both sides of an equation will remain equal, when both sides are
multiplied by the same value.
Therefore, let's multiply both sides by 100,
2.3p – 10.1 = 6.5p – 4 – 0.01p
100(2.3p – 10.1) = 100(6.5p – 4 – 0.01p)
230p - 1010 = 650p - 400 - p
Therefore, another equivalent solution is 230p - 1010 = 650p - 400 - p
