(Question 2) I put down 10x=20 then did 10x/10=20/10 then got x=2, what do I do with the M

m just means measure. it’s not a variable. you also did your math wrong.

Step-by-step explanation:

it’s tells you that angle ABC is 60°. so the correct equation would be 20+10x=60, and then you would subtract 20 from both sides and get 10x=40. then you divide to get x=4.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
