-6x <= 4x + 2
Subtract 4x from both sides
-10x <= 2
Divide -10 on both sides
Final Answer: x >= -1/5
Answer:41
Step-by-step explanation:
Answer:
f^-1(x)=³√[(x+7)÷4]
Step-by-step explanation:
f(x)=4x^3-7
y=4x^3-7
interchange 'y' with 'x'
x=4y^3-7
make y the subject
4y^3=x+7
divide by 4 both sides
y^3=(x+7)÷4
multiply by the cube root both sides
³√(y^3)=³√[(x+7)÷4]
y=³√[(x+7)÷4]
f^-1(x)=³√[(x+7)÷4]
Answer:
Object point Q (x,y) ------------- image point Q'( -y,x)
Step-by-step explanation:
When a point A (x,y) is rotated 90 degrees counterclockwise about the origin the resulting image of the point is A'(-y,x)
This means first you alternate the positions of x and y coordinates then add a negative sign on the now new y coordinate.
Example a point B(2,3) rotated 90° counterclockwise about the origin will form an image B'(-3,2)
So if point Q (x,y) ------------- image Q'( -y,x)
Substitute real values for (x,y) coordinates to get correct answer.
