Reflect ABC over the x axis translate by <-3,-1>, and rotate 180 degrees around the origin
Following a 180-degree rotation, the new points are (3,1)
The size of the image will either rise or decrease depending on the answer to the question. And there are two ways to rotate: clockwise and counterclockwise. The coordinate values will vary depending on the quadrant.
Consequently, the new points upon rotation are (3,1).
What do translation, rotation, and reflection mean?The word "reflection" flips or creates a mirror image of the object. An picture is rotated by rotating it either clockwise or anticlockwise. Finally, translation moves certain parts of the picture.

The cross-section of a lean-to shelter is in the shape of a triangle. The base of the
triangle is 6 feet more than twice its height. If the area of the triangle is 88 square feet,determine the length of the base and the height of the triangle in feet
Answer:
Step-by-step explanation:
Givens
Let the height = x
Let the base = 2*x +6
Let the area = 88 square feet.
Formula
A = Base * height / 2
Solution
88 = (2x + 6)*x/2 Multiply both sides by 2
88*2 = (2x+6)*2*x/2 Combine
176 = (2x + 6)*x Remove the brackets
176 = 2x^2 + 6x Subtract 176 from both sides
0 = 2x^2 + 6x - 176 This factors without the quadratic
0 = (2) (x^2 + 3x - 88)
0 = 2 (x +11)(x - 8)
Note: x + 11 has no meaning. Measurements of this type cannot be minus. What is - 11 feet.
x - 8 =0
x = 8
Answer
height = 8 feet
base = 2*8 + 6
base = 22

b. Do transformations of the form y=|x|+k affect the axis of symmetry? Explain.
A line that bisects or cuts an objects into two equals parts is called the axis of symmetry for that object. The axis of symmetry creates a mirror-like reflection of each side of the object.
The function f(x) = |x| is called an absolute value function. The highest or lowest point on the graph of the absolute value function is called the vertex. The absolute value graph has an axis of symmetry through the vertices.
The axis of symmetry (x=0 or y-axis) is the line that divides the graph into two congruent halves. Translate is a transformation that moves the graph horizontally or vertically, but does not change its overall shape or orientation.
So, it does not affect the axis of symmetrical. Is symmetrical about the Y axis (axis of symmetry).

[tex]y = 800 (1.15)^{x}[/tex] is an not exponential decay factor related to growth factor 15%.
[tex]y = 1200 (1.05)^{x}[/tex] is an not exponential decay factor related to growth factor 5%.
[tex]y = 3(0.85)^{x}[/tex] is an exponential decay factor of 85%, then the related to 20%.
We know that,
Exponential Decaying factor is [tex]y = ab^{x}[/tex]
Where, 0<b<1
The decay rate is expressed as a percentage. We convert it to a decimal by simply reducing the percent and dividing it by 100.
Growth factor is the factor by which a quantity multiplies itself over time. Growth rate is the addend by which a quantity increases (or decreases) over time.
Here,
Option(1) : [tex]y = (0.3)(0.5)^{x}[/tex]
Then, 0.5 < 1 (0.5 means 50%)
So, [tex]y = (0.3) (0.5)^{x}[/tex] is an exponential decay factor .
Hence, [tex]y = (0.3) (0.5)^{x}[/tex] is an exponential decay factor of 50%.
Option(2) : [tex]y = 2000(\frac{4}{5}) ^{x}[/tex]
Then, 4/5 < 1
⇒ 0.8 < 1
So, [tex]y = 2000(\frac{4}{5} )^{x}[/tex] is an exponential decay factor.
Hence, [tex]y = 2000(\frac{4}{5} )^{x}[/tex] is an exponential decay factor of 15%.
Option(3) : [tex]y = 800 (1.15)^{x}[/tex]
Then, 1.15 > 1
So, [tex]y = 800 (1.15)^{x}[/tex] is an not exponential decay factor.
Hence, [tex]y = 800 (1.15)^{x}[/tex] is an not exponential decay factor of 115%, so it is not decay factor, then the related to growth factor 15%.
Option(4) : [tex]y = 1200 (1.05)^{x}[/tex]
Then, 1.05 > 1
So, [tex]y = 1200 (1.05)^{x}[/tex] is an not exponential decay factor.
Hence, [tex]y = 1200 (1.05)^{x}[/tex] is an not exponential decay factor of 105%, so it is not decay factor, then the related to growth factor 5%.
Option(5) : [tex]y = 3(0.85)^{x}[/tex]
Then, 0.85 < 1
So, [tex]y = 3(0.85)^{x}[/tex] is an exponential decay factor.
Hence, [tex]y = 3(0.85)^{x}[/tex] is an exponential decay factor of 85%, then the related to 20%.
Therefore,
[tex]y = (0.3) (0.5)^{x}[/tex] is an exponential decay factor of 50%.
[tex]y = 2000(\frac{4}{5} )^{x}[/tex] is an exponential decay factor of 15%.

What is the equation of the line that passes through the point (-1,6)and has a slope of −1
Answer:
y = -x + 5
Step-by-step explanation:
slop m = -1, x = -1, y = 6
y = mx + b
6 = (-1)(-1) + b
6 = 1 + b
b = 5
so y = -x + 5
Find the slope of the line through (3,5) , parallel to y=5 x-1
Find the slope of the line through (3,5) , parallel to y=5 x-1
Slope=5
How to find slope?
Given:
y=5x-1 ( where, slope=5)
Any line parallel to y=5x-1 also has slope 5
What is the line?
y=5x+b
We can find b ,using the given points (3,5)
5=15+b
b=-10
The line is, y=5x-10
What is a slope?
In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.The letter m is frequently used to represent slope; the reason for this usage is unclear, but it can be found in O'Brien's and Todhunter's versions of the equation for a straight line, respectively, where they are written as y = mx + b and y = mx + c.To learn more about slope, refer:
