Answer:
The last one.
Step-by-step explanation:
The solutions with the horizontal lines are wrong because then h(x) would be -1 and 1 respectively.
The subtlety is in the open or closed dot. x ≥ -1 means that -1 is included, which is drawn as a closed dot. x < -1 means that -1 is excluded, which is drawn as an open dot.
Hence the last graph is the correct one.
Answer:
yeah it is an expression
Explanation:
An expression may refer to any of the following:
A combination of letters, numbers, or symbols used to represent a value of a variable. ..
X+y=23 (x and y added equal the number of baskets made)
2x+3y=53 (since each basket is worth a certain amount of points, x and y must be multiplied by their amount of baskets and added together to get the total number of points)
Hope this helps!
Answer:
15 %
Step-by-step explanation:
42 = members of team A
60 = members of team B
Let x = percent of members transferred
0.01x × 60 = 0.6x = no of members transferred
60 - 0.6x = 42 + 0.6x
60 = 42 + 1.2x
18 = 1.2x
x = 15
15 % of the members on Team B must be transferred to Team A.
Check:
60 - 0.6 × 15 = 42 + 0.6 × 15
60 - 9 = 42 + 9
51 = 51
OK.
