R + (-4) = 7 solve for r

Step-by-step explanation:

r -4 = 7

: r= 7+4

r= 11

answer is 11

11

Step-by-step explanation:

Add 4 to both sides to get rid of -4 or if you want think of it as moving -4 to the other side and turning it into positive if its negative and negative if its positive

r=11

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
