In order to draw x ≤ -10 on a number line, first draw a closed dot at -10. This is because we have a ≤ and not a <. If we had a <, it would be an open dot.
Next, since we want x to be smaller, draw an arrow pointing towards all numbers that are smaller. This arrow would point to the left.
Answer:
Ans: 29
Step-by-step explanation:
soln:
Given,
x=3 and y=-2
Now,
x^2-3xy+1/2y^2
= 3^2-3×3×(-2) +1/2(-2)^2
= 9+18+4/2
= (18+36+4) /2
= 58/2
= 29 Ans
