the x-axis.
-))
A)
Reflect it over the line y = -x and then reflect it over the x-axis.
B)
Rotate the image 270° counterclockwise and then reflect it in the x-axis.
Rotate the image 180° counterclockwise and then reflect it in the x-axis.
D)
Reflecting it over the x-axis, then over the y-axis and finally over the line y
= X
B is the answer because it results in the shape being opposite of the original.

For questions 1 - 4, use your graphing calculator to help you sketch a graph of the function given. Then state whether each function is one-to-one. In each case, explain how you know.
Answer:
the function is one-to-one
Step-by-step explanation:
The graph is attached.
The function is one-to-one, because no horizontal line intersects the graph at more than one point.
Type the correct answer in the box.
Winston is creating a rectangular piece of 8-bit art using squares that are x pixels wide. The length of the rectangular piece, in pixels, is represented by the function l(x) = x + 24, and the width of the rectangular piece is represented by w(x) = x + 16.
Write the standard form of the function which describes the total area of the rectangular piece, a(x), in terms of x, the side length of each square pixel.
Area=l×w
Function:-
[tex]\\ \sf\longmapsto (l*w)(x)[/tex]
[tex]\\ \sf\longmapsto l(x)*w(x)[/tex]
[tex]\\ \sf\longmapsto (x+24)(x+16)[/tex]
[tex]\\ \sf\longmapsto x^2+40x+384[/tex]
5 < x + 10
what does x equal??
Hello there! :)
5<x+10
Move all the variables to the left, using the opposite operation:
-x<10-5
-x<5
x>-5
When we divide by a negative variable, we flip the inequality sign.
Therefore, x>-5Hope this helps!

Answer:
x>-5
Step-by-step explanation:
x needs to be any number greater than 5, as you can see, this is an inequality not an equation so there is no defenite answer. if youdo the math, 10+-5 is 5, our answer cannot equal 5 it has to be greater than 5, Therefore, x can be any number greater than -5

What is the axis of symmetry for f(x) = 2x2 − 4x + 5? x = −2 x = −1 x = 1 x = 2
Step-by-step explanation:
for a quadratic equation
y = ax² + bx + c
the x value for the axis of symmetry is
x = -b/(2a)
in our case
y = 2x² - 4x + 5
a = 2
b = -4
x = - -4/4 = 4/4 = 1
x = 1 is the correct answer.
