Im pretty sure you need to divide 155 by 4 or 48. try it and see what you get. then ask your teacher if you did it right. always ask questions.
Answer:
18
Step-by-step explanation:
Points A B C D and E are collinear.
X² + x - 20
= (x+5)(x-4)
x + 5 = 0
x = -5
x - 4 = 0
x = 4
hence the answer is C
Answer:
right there and its ANSWER
Step-by-step explanation:
The correct answer is d. Solid line with shading on the side that includes the origin
We can tell this for two reasons. Firstly, since it is "greater than or equal to" we use a solid line. If it were just "greater than" than we would have used a dotted line.
Secondly, to tell if the origin should be shaded is by plugging in (0,0) and seeing if it is a true statement. If it is true, it is shaded.
5x + y ≥ -10
5(0) + 0 ≥ -10
0 + 0 ≥ -10
0 ≥ -10 (TRUE)
