The transformation of the graphs is
1st graph is (x,y)→(x-4,y+2)
2nd graph is (x,y)→(x+6,y+0)
Given that,
There are two graphs with 2 triangles in each graph.
We have to find the transformation of the graphs.
Take the 1st graph,
We have 2 triangles ABC and A'B'C'.
The points are,
A=(0,0), B=(3,-4) and C=(-1,-2)
A'=(-4,2), B'=(1,-2) and C'=(-5,0)
We get the transformation as
(x,y)→(x-4,y+2)
Check the A and A' points
The A terms goes left for 4 times to A' so we take x-4 and the A terms goes up for 2 times to A' so we take y+2.
Similarly,
The B terms goes left for 4 times to B' so we take x-4 and the B terms goes up for 2 times to B' so we take y+2.
Similarly,
The C terms goes left for 4 times to C' so we take x-4 and the C terms goes up for 2 times to C' so we take y+2.
Now the 2nd graph,
We have triangle FCP and F'C'P'
The points are,
F=(-5,5), C=(-2,5) and P=(-3,0)
F'=(1,5), C'=(4,5) and P'=(3,0)
We get the transformation as
(x,y)→(x+6,y+0)
Check the F and F' points
The F terms goes right for 6 times to F' so we take x+6 and the F terms remain same so we take y+0
Similarly,
The C terms goes right for 6 times to C' so we take x+6 and the C terms remain same so we take y+0
Similarly,
The P terms goes right for 6 times to P' so we take x+6 and the P terms remain same so we take y+0
Therefore, The transformation of the graphs is
1st graph is (x,y)→(x-4,y+2)
2nd graph is (x,y)→(x+6,y+0)

I talked to my professional tutor about this, she didn’t happen to explain the answer though. She’s been working as a teacher for 20 years.
If a bus is charged $122, how many people do you think it contains?
Answer:
38 people
Step-by-step explanation:
In this case, we can see that, being two people, the cost is 14 and when it is double, that is, 4 people, the value is not 28 but 20.
Which means that there is an additional value that is being charged for the vehicle, that is:
let "c" be the value of the vehicle and "x" be the value per person
c + 2 * x = 14
c + 4 * x = 20 => c = 20 - 4 * x
replacing:
20 - 4 * x + 2 * x = 14
-2 * x = 14-20
-2 * x = -6
x = 6/2
x = 3
for C:
c = 20 - 4 * 3
c = 8
Which means that the formula for the value of the input would then be:
e = 8 + 3 * n
where "n" is the number of people.
Now, we are told that for e = 122
122 = 8 * + 3 * n
3 * n = 122 -8
n = 114/3
n = 38
which means that for that bus there are a total of 38 people
Which values are in the solution set of the compound inequality? Select two options. 4(x + 3) ≤ 0 or x+1>3 –6 –3 0 3 8
The values -3 , -6 , 3 , 8 are in the solution set of the compound inequality 4(x + 3) ≤ 0 and x + 1 > 3
Given, a compound inequality
4(x + 3) ≤ 0 and x + 1 > 3
Now, on solving the first inequality, we get
4(x + 3) ≤ 0
4x + 12 ≤ 0
On subtracting both the sides by 12, we get
4x + 12 - 12 ≤ 0 - 12
4x ≤ -12
On dividing both the sides by 4, we get
4x/4 ≤ -12/4
x ≤ -3
So, the solution set of the 4(x + 3) ≤ 0 inequality be, x ≤ -3 i.e. all the real numbers less than -3.
Now, on solving the second inequality, we get
x + 1 > 3
On subtracting both the sides by 1, we get
x + 1 - 1 > 3 - 1
x > 2
So, the solution set of the x + 1 > 3 inequality be, x > 2 i.e. all the real number greater than 2.
Now, the values in the solution set of the compound inequality
4(x + 3) ≤ 0 and x + 1 > 3 be,
x ≤ -3 and x > 2.
As, we can see -3 , -6 , 3 , 8 are satisfying the condition.
Hence, -3 , -6 , 3 , 8 are the values in the solution set of the compound inequality 4(x + 3) ≤ 0 and x + 1 > 3.

Evaluate the following permutations and combination
a) N = ( 3P4 ) ( 5P2 ) b) N = (3C2) / (4C2)
By using the definitions of combinations and permutations:
a) The first permutation is not defined.
b) N = (³C₂) / (⁴C₂) = 1/2.
How to evaluate the permutations and combinations?A permutation:
ⁿPk is written as:
ⁿPk= n!/(n - k)!
(the denominator only appears if nk)
And a combination is written as:
ⁿCk = n!/(n - k)ka)
We have the product of two permutations, but there is a problem:3P4 The first number is the size of the set, and the second is the number of elements we take from that set.
In that permutation we have a set of 3 elements and we need to select 4, so that permutation is not defined.
b) (³C₂) = 3!/(3 - 2)!*2! = (3*2*1)/(2*1) = 3
(⁴C₂) = 4!/(4 - 2)!*2! = (4*3*2*1)/[(2*1)*(2*1)]
= 3*2 = 6
Then the quotient can be written as:
(³C₂) (⁴C₂) = 3/6 = 1/2.

(a) Find the probability that exactly three of them fail the test.
(b) Find the probability that fewer than three of them fail the test.
What is Binomial Distribution?
The probability of success is said to follow a binomial distribution when many similar and independent Bernoulli trials are conducted. The likelihood of success and the quantity of tries are its dimensions. For every trial, the chance of success is the same.
State emission test failure probability is 0.05.
12 vehicles total are present.
Let's look at failing the test as a victory. If success is represented by p, then p = 0.05.
Considering that n represents the number of cars, n equals 12.
Let X represent how many vehicles fail the test.
So, X ∼ Bin (8,0.05)
P(X=x)= [tex]^{n}C_{x}p^{x}(1-p)^{n-x}[/tex]
= [tex]^{12}C_{x}0.05^{x}(0.95)^{12-x}[/tex]
a) Probability that exactly 3 automobiles fail the test is given by,
P(X=3)= [tex]^{12}C_{3}0.05^{3}(0.95)^{12-3}[/tex]
=0.01733
So, the probability that exactly 3 automobiles fail the test is 0.01733.
b) Probability that fewer of them than 3 fail the test is given by,
P(X<3)= P(X≤2)
= P(X=0)+P(X=1)+P(X=2)
= [tex]^{12}C_{0}(0.05)^{0}(0.95)^{12}[/tex] + [tex]^{12}C_{1}(0.05)^{1}(0.95)^{11}[/tex]+[tex]^{12}C_{2}(0.05)^{2}(0.95)^{10}[/tex]
= 0.9803
Hence, the probability that fewer than 3 of the automobiles fail the test is
0.9803.

What is the equation in slope-intercept form of the line that passes through the point (2,-5) and is perpendicular to the line represented by y=2x+6
Answer:
y = (-1/2)x - 4
Step-by-step explanation:
y = 2x + 6
Perpendicular: y = (-1/2)x + 6
m = (-1/2); (2, -5)
(x₁, y₁)
y - y₁ = m(x - x₁)
y - (-5) = (-1/2)(x - 2)
y + 5 = (-1/2)x + 1
-5 -5
----------------------------
y = (-1/2)x - 4
I hope this helps!
Step-by-step explanation:
the slope-intercept form is
y = ax + b
"a" being the slope, "b" being the y-intercept (the y- value when x = 0).
the slope is the ratio (y coordinate difference / x coordinate difference) when going from one point on the line to another.
a perpendicular slope simply turns the original slope upside-down with x and y, and it flips the sign.
the slope of the origins line is 2 = 2/1.
the perpendicular slope is -1/2.
so, the equation looks like
y = -1/2 x + b
to get b we use the point coordinates :
-5 = -1/2 × 2 + b = -1 + b
-4 = b
so, the full equation is
y = -1/2 x - 4

The height in feet, of the rocket above the ground at t seconds after launch is given by the function h(t)=-16 t²+72 t+7. How long will it take the rocket to reach its maximum height? What is the maximum height?
The rocket reaches its maximum height at second(s) after launch.
(Simplify your answer.)
The maximum height reached by the object is feet.
(Simplify your answer.)"
The time taken for the rocket to reach its maximum height is; 2.25 seconds.
The maximum height reached by the toy rocket by evaluation is; 88 feet.
What is the maximum height reached by the rocket?It follows from the task content that the maximum height reached by the rocket is to be determined.
The given function is; h (t) = -16 t² + 72t + 7.
Since it follows from evaluation that; at maximum height, the rate of change of height to time is equal to 0.
Therefore; at maximum height;
h'(t) = 0
h'(t) = -32t + 72 = 0
-32t = -72
t = -72/-32
t = 2.25 seconds.
Ultimately, the time taken for the rocket to reach its maximum height is; 2.25 seconds.
Also, the maximum height reached by the rocket is at; h (2.25);
h(2.25) = -16(2.25)² + 72 (2.25) + 7

A line passes through the points (6,0) and (9,1). What is its equation in slope-intercept form?
Equation of line will be y = x/3 - 2
A line's equation can be written in many forms in which one is slope-intercept form.
Equation in slope-intercept form is written as y = mx + c where
m = slope
c = y intercept
Slope shows the steepness of the line. It can be given by change in y axis by change in x axis.
y intercept is the point where the line cuts the y axis that is x = 0 at this point.
Points given to us are (6 , 0) and (9 , 1)
slope = [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
m = (1 - 0) / (9-6)
m = 1/3
For c put values of either point in the equation as they both are on the line so they both will satisfy the equation.
y = mx + c
0 = (1/3)*6 + c
0 = 2 + c
c = -2
now put values of m and c in the equation and get a general equation.
Therefore of equation of line will be y = x/3 - 2
