QUESTION A AND B PLEASEEE I REALLY NEEDED THE ANSWER

a) A ( 7,0 )

   B ( 0,7 )

b) y = x

Step-by-step explanation:

Since the radius is 7,

So,

a)   A ( 7,0 )

     B ( 0,7 )

b) The coordinates of O are (0,0)

while M are to be founded.

Using Midpoint formula to find M

M =

M =

M = (3.5,3.5)

Now, Finding the equation of line OM

Slope = m =

Slope =

Slope =

Slope = 1

Now, the y-intercept,b

Putting M(3.5,3.5) in slope intercept equation to get y-intercept, b

=>

=> 3.5 = (1)(3.5) + b

=> b = 3.5-3.5

=> b = 0

Now, the equation becomes

=>

=> y = (1)(x) + (0)

=> y = x

This is the required equation

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
