Which description best describes the solution to the following system of equations?

y = −one halfx + 9
y = x + 7

lines y = −one halfx + 9 and y = x + 7 intersect the x-axis.
lines y = −one halfx + 9 and y = x + 7 intersect the y-axis.
line y = −one halfx + 9 intersects the origin.
line y = −one halfx + 9 intersects line y = x + 7.

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
