Answer:
a4
Step-by-step explanation:
the answer is "a4" because in algebra when letters are being multiplied by numbers there isn't meant to be a space between the two(i.e. 4x)
hope this helps :) im sorry if it's unclear have a nice day !!
Answer:
midpoint = (-2.5 , - 10)
Step-by-step explanation:
midpoint =( ((x1 + x2)/2) , ((y1+y2)/2)) )
= ( ((-2 + -3)/2) ,(( -8 + -10)/2) )
= ( -2.5 , -10)
Answer:
5,0 is the answer of ur question
Answer:
Step-by-step explanation:
The formula for the length of a vector/line in your case.
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.
