Answer:
x≥2
Step-by-step explanation:
12x+6\ge \:9x+12
12x+6-6\ge \:9x+12-6
12x\ge \:9x+6
12x-9x\ge \:9x+6-9x
3x\ge \:6
<em>6 + 7r - 4 </em>× <em>11
</em>=<em> 7r + (6-4) </em>× <em>11
= 14r+11</em>
Answer:
(2.4, -1.2)
Step-by-step explanation:
Start by moving the x and the y to the same side and moving the number across the equal sign in both equations. We should now have y-0.45x=-2.3 and 2y+4.2x=7.8. We can use the elimination method by multiplying the first equation by -2 to get -2y+0.9x=4.6 and 2y+4.2x=7.8. From there, add the two equations together, eliminating y (-2+2=0). We now have 5.1x=12.4; divide both sides by 5.1 to get x=2.4. Then, in any of the two equations, let's use y-0.45x=-2.3, substitute x with 2.4. Now we have y-1.08=-2.3. Add 1.08 to both sides to get y=-1.22; round that to the nearest tenth to get -1.2.
I think it B or D I hope i don’t get it wrong
Answer:
A
Step-by-step explanation:
The perimeter is more since the shape gained many new sides but the area is less because the rectangle lost a little square
