Answer:

Q'(1, -4)

R'(1, -3)

S'(0, 4)

T'(0, -5)

Step-by-step explanation:

If A is the X-coordinate of a pre-image point, and B is the X-coordinate of the image, then we want 4 to be the midpoint of those values. That is ...

(A + B)/2 = 4

A + B = 8 . . . . . multiply by 2

B = 8 - A . . . . . subtract A

So, the reflection over x=4 is the transformation ...

(x, y) ⇒ (8 -x, y)

The y-value stays the same, and the new x-value is the result of subtracting the x-coordinate from 8.

The given points have two different x-coordinates: 7, and 8. The corresponding image coordinates are 8-7 = 1 and 8-8 = 0.

Your points are ...

Q'(1, -4)

R'(1, -3)

S'(0, 4)

T'(0, -5)

How many solutions are there to the equation below?<br> 6x + 33 = 6(x+6)

Ainat [17]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

Let's solve ~

$6x + 33 = 6(x + 6)$

$6x + 33 = 6x + 36$

Here, 6x is present on both the sides of equation so they cancel out ~ therefore there is no one solution satisfying the equation ~

What are the coordinates of the turning point for the function f(x) = (x + 2)3 − 4?

AnnZ [28]

Answer:A

Step-by-step explanation:

Given

$F(x)=(x+2)^3-4$

Turning Point is the point where the graph changes its nature i.e. either increasing to decreasing or decreasing to increasing

to find turning point

$F'(x)=3(x+2)^2+0$

For critical point

F'(x)=0

$3(x+2)^2=0$

x+2=0

x=-2

$F(x)=(-2+2)^3-4=-4$

thus

(-2,-4 ) is the turning Point where Function changes its nature

(b) Find the equation of the straight line which passes through 81 +88 (i) the point (3, 2) and makes an intercept on the x-axis

ad-work [718]

3x+y=0 and x+2y=7

a= intercept on x axis

b= intercept on y axis

from the question

a=2b

x/2b+ y/b=1

x+2y=2b

since it passes through the point (3,2)

then 3+4=2b

7/2=b

x+2y=7 putting the value of b

ii) given b =3a

then x/a+ y/ 3a =1

3x+y=3a

it passes through ( -1,3) then

-3+3=3a

a=0

3x+y=0

Anyone who could do these 8 listed questions I will give a generous amount of points. Please make sure to list all the angles th

k0ka [10]

Answer:

1) 0, 180

2) 90

3) 3pi/2

4) pi/2, -3pi/2

5) 90, 270

6) 0

7) pi

8) -2pi, 0, 2pi

Step-by-step explanation:

1) sinx = 0

x = 0, 180, 360

2) sinx = 1

x = 90

3) sinx = -1

x = 270 or 3pi/2

4) sinx = 1

x = pi/2, pi/2 - 2pi = -3pi/2

5) cosx = 0

x = 90, 360

6) cosx = 1

x = 0, 360

7) cosx = -1

x = pi

8) cosx = 1

-2pi, 0 , 2pi
