Answer with explanation:
The given function is,
f(x)=x
We can Write it as,replacing f(x) by y
→y=x ------------------(1)
When , f(x) is replaced by in the above equation, the above equation reduces to
Similarly, Replacing f(x) by y in this equation also,the equation becomes
→→ y = - 2 x ---------------(2)
Plotting the graph of , Line 1 and Line 2
Now, when line 1 is reflected either through , x axis or y axis, the equation of line 1 becomes
→→y= -x
As,→ if there would have been vertical stretch, distance between origin and points on the curve would have been Larger.
But , →why compression because distance between axis of reflection and curve which has been compressed, that is , y=-2 x, has reduced.
Option D: Horizontal reflection over y-axis and horizontal compression

Answer:
The answer is
A. 529.66 ft²
Step-by-step explanation:
The picture of the composite figure is not given,
But find attached the figure.
The composite consists of two solid shapes
1. Cylinder
2. Rectangular prism
To solve for the total surface area of the composite
Let us solve for the total surface area of the cylinder
Given radius r= 4ft
Height h=5ft
A= πr²+2πrh-πr²
N/B we subtracted the second circular surface since it is joined to the rectangular prism
A= 3.142*4²+2(3.142)*4*5-3.142*4²
A= 50.272+125.68-50.272
A=125.68ft²
We proceed to find the area of the rectangular prism
We know that the prism has 6 sides
Hence area
A= 2(11*6)+ 2(8*6)+2(11*8)
A= 132+96+176
A= 404ft²
Hence total surface area is
404+125.68= 529.68ft²
QUESTION
Your equation is 2x+3y=2 and you need to find the slope.
EXPLANATION
There are many ways to find the slope with an equation like this. I'm going to change the equation into slope-intercept form.
Slope-intercept form is formatted like this:
y=mx+b
m represents the slope. The first thing you need to do is leave 3y alone to change the equation into slope-intercept form. That means you need to subtract 2x from both sides.
The next thing you need to do is leave y alone, just like the slope-intercept form example. To leave y alone, you need to divide 3y by 3.
Now the equation has been changed to slope-intercept form. In the equation, m has been replaced by , which means that is your answer.
