Words to the wise: Please express exponentials as x^2, not x2.
x2 + y2 = 81 should be <span>x^2 + y^2 = 81 = 9^2
Comparing this to x^2 + y^2 = r^2, we see that r= radius=9. y-intercepts are where x=0, so purposely set x=0 and solve for y:
0^2 + y^2 = 9^2. Then y = 9 or y = -9.
The graph intersects the y-axis at (0,9) and (0, -9).</span>
Answer:
1 5/12
Step-by-step explanation:
find the common factor of the denominators (3 and 4) which is 12 then just multiply the 2 in 2/3 by 3 since 12 is the third common factor for 3 and you do the same thing with 3/4, multiply the 3 by 3. then you add 8/12 + 9/12 to get 17/12 then 17 goes into 12 once plus 5 left over so as a mixed number its 1 5/12
