2•y>10
The “>” has a line underneath it
Answer:
1:2
Step-by-step explanation:
if the one side is twice the length that means that you need two of them to make the one thus the ratio 1 to 2
6.95 to one decimal place would be 7 because if it was 6.9 then it would round to 7 and the 6.95 rounds the 9 to a 10 and you cant have 6.10 so it would be 7.
Step-by-step explanation:
0.2m^3 = 0.0000002 cm^3
I one is 8x<24 and -8≤2x-4
Hence x <24/8 =3 and -4≤2x: divide by positive 2 to get -2≤x
Hence solution is -2≤x<3
Therefore c is the correct matching for 1.
2) 5x-2>13 or -4x≥8
i.e. 5x>15 or x≤8/(-4) = -2 (since dividing by negative inequality reverses)
Or x>3 or x ≤-2
Hence solution is two regions to the right of 3 excluding 3 and left of -2 including -2.
Graph b is the correct match.
3) -25≤9x+2<20
Subtract 2
-27≤9x<18: Now divide by positive 9
-3≤x<2
Hence graph is the region between -3 and 2 including only -3.
Graph a is correct matching for question 3.
