A machine heats up a single point by shining several lasers at it. The
equations y = x + 1 and y = -x + 7
describe two of the laser beams. Graph
both of these lines to find the coordinates
of the heated point.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

-1/4 > -1 2/3. -1/4 is greater than -1 2/3 because it is closer to 0 on the number line.
