Complete the description of what happens to a figure when the given sequence of transformations is applied to it: (x,y) → (-x,y); (x,y) → (0.6x, 0.6y);(x, y) = (x - 5, y + 5)
Reflection over the (y-axis/x-axis/origin); (movement upwards/translation/transformation/dilation) with a scale factor of 0.6; translation 5 unit left and ____ units up.
Answer:
Reflection over the y-axis; dilation with a scale factor of 0.6; translation 5 unit left and 5 units up.Step-by-step explanation:
The results of the given transformations are ...
(x,y) → (-x,y); reflection over the y-axis(x,y) → (0.6x, 0.6y); dilation by a factor of 0.6(x, y) → (x - 5, y + 5); translation left 5 and up 5_____
Additional comment
Changing the sign of the x-coordinate moves a point horizontally to the other side of the y-axis, reflecting it over the y-axis.
Multiplying coordinate values by the same factor effects a dilation about the origin by that factor.
Adding to the x-coordinate moves the point to the right; adding to the y-coordinate moves the point up. (Subtracting from x moves the point left.)

a rectangle has a length of 9 inches and an area of 48 inches. it’s width, w, is unknown. explain why the following equation cannot be solved to find the correct width of the rectangle? w+9=48
Answer:
This equation cannot be solved to find the correct width of the rectangle because the formula for the area of a rectangle is area = base times the height. Therefore, you can't just simply subtract 9 from 48 to get the width. Instead, you have to divide 48 by 9 to find the width, since 48 is the area and 9 is the length.

Next, the team wants to explore how it can change the steepness of the curved pit.
Identify how the graph of each equation compares with the graph of the parent quadratic equation, y = x2.
Drag the equations to the correct location on the chart. Not all equations will be used.
Given that the parent function, y = x², has a leading coefficient of 1, the
following are the comparisons of the equations with the parent functions;
[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]
How can the correct location of each equation be found?The parent function is y = x²
The leading coefficient of the parent function = 1
The steepness of a quadratic equation is given by the value of the
leading coefficient.
When the leading coefficient is larger than 1, we have;
The function is steeper than y = x²
When the leading coefficient is a fraction larger than 0 but lesser than 1, we have;
The function is less steep than y = x²
Which gives;
[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]
The function y = -x² is inverted has the same steepness as y = x², but will not be used.

Step-by-step explanation:
In first bag there is 15 M&M's ANd second bag has a total of 9 M&M's so that means there are a total of 24 M&M's.
In the first bag there is 5 blue M&M's and in the second bag there is a total of 2 blue M&M's so there is a total of 7 blue M&M's all together.
so there are 7/24 M&M's ( what were going to do it convert it into percents.
To do this were going to use these steps.
were going to divided the number of blue M&M's by the total of M&M's all together so 7 divided by 24=?And then next we are going to multiply the result by 100 which=?Calculations
7 divided by 24=0.291666.

Answer:
The first, third, andd sixth choice is correct.
Step-by-step explanation:
The y-intercept is when x = 0.
So if we plug x = 0 into the equation.
y = -4(0) + 98
y = 98
So the first choice is correct.
y = mx + b
y = -4x + 98
m = slope
b = y-intercept
So, the slope must mean it's decreasing.
So the third choice is correct.
Let try plugging in values for x.
y= -4(0) + 98 = 98
y= -4(1) + 98 = 94
y= -4(2) + 98 = 90
x stands for the number of days the students miss.
We see the bigger the value we put in for x, the lower the test score is aas represented by y.
So, the sixth choice is correct.
we know that,
y intercept exist when x = 0
so,
⇢y = -4x +98
⇢y = -4 x 0 +98
⇢y = 98
so , the expected test score is 98
Based on the linear regression equation, the slope means that for every missed class, the expected tast score decreases by 4 points✓when x = 0
y = -4(0) +98
when x = 1
y= -4(1) +98 = 94
when x = 2
y= -4(2) +98 = 90
we can see the decresement of 4 points
Based on the linear regression equation, as the number of days a student misses class increases the expected test score decreases ✓We can see that the increament in absent days lead to lower scores ( one class = 4 points)

A group of friends wants to go to the amusement park. They have $131.75 to spend on parking and admission. Parking is $18, and tickets cost $22.75 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.
Answer:
3 people
$9.5 left over
Step-by-step explanation:
pp = 18 + 22.75
pp = 40.75
total people who can go = 131.75/pp
tp = 131.75/pp
tp = 3 remainder $9.5
(this is if they all arrive in individual cars)
The number of people that can go to the amusement park are 5 .
Concept:First, we need to find the amount left after deducting parking charges. Then the remaining amount can be divided by the price of one ticket to find out how many persons can buy the ticket from the same amount.
How to solve the given problem?The parking charges are $18 and the ticket costs $22.75 per person.So amount left after parking charges = $131.75 -$18 = $113.75To find the number of persons, let x be the no of tickets that can be purchased from the given amount.So the expression can be framed as 22.75x = 113.75.On solving the expression, we get x = 5 nos.Thus, 5 number of persons can go to the amusement park.

Answer:
Point slope form of the equations:
y = -3x + 8
y = 2x - 2
Solution to the system of equations:
(x, y) ==> (2, 4)
Step-by-step explanation:
6x + 2y = 16
2x - y = 2
6x + 2y = 16

6x + 2y = 16
4x - 2y = 4
10x = 20
/10 /10
x = 2
Now, we solve for y:
