How can you tell from a graph whether two functions are inverses of each
other?
o the graphs of the functions are reflections across the line y=x.
o the graphs of the functions are reflections across the x-axis.
o the graphs of the functions are reflections across the y-axis.
o it is not possible to tell from a graph if functions are inverses of each other.
Answer:
if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.

The agriculture club is planting vegetable gardens of land that measures 1 3/4 of an acre. Each garden will measure 1/8 of an acre. What is the greatest number of gardens that can be planted?
Answer: 14 gardens
Explanation:
1. You can either turn the fractions into decimals (1.75 and 0.125) or make the denominators the same (1 6/8 and 1/8)
2. multiplying 3/4 by the 2 to get the least common multiple, which in this case is 8. (3/4x2=6/8)
3. Divide the number of acres available (1 6/8) by the number of acres needed for each garden (1/8) to get the answer. (1 6/8÷1/8=14)
help me with this please
Answer: B
Step-by-step explanation:
Well if it's a greater than statement you can rule out C and D because those are less than symbols ( > = Less, < = Greater) It can't be A because thats his starting amount. The x means how many months it will take for him to get more than 70 stamps

Answer:
1. -39
2. 49
3. 32
Step-by-step explanation:
absolute values are always positive!!!
|-39| = 39 but since there is a minus sign outside the lines it is -39
|-44| = 44+5= 49
And 50 - 18 = 32 (|-18| = 18)

Solve:
6 divided by 1/5
Answer:
30
Step-by-step explanation:
6/1 divided by 1/5...(turn the second fraction into 5/1)
therefore...6/1 multiplied by 5/1
=6 multiplied by 5= 30
6 divided by 1/5 is equal to 30.
To solve 6 divided by 1/5, we can multiply the dividend (6) by the reciprocal of the divisor (1/5). The reciprocal of a fraction is obtained by flipping it, so the reciprocal of 1/5 is 5/1.
6 ÷ 1/5 = 6 × 5/1
Multiplying:
6 × 5 = 30
Therefore, 6 divided by 1/5 is equal to 30.

solve using elimination x+2y=4 -x-y=2
Answer:
x=-8 y=6
Step-by-step explanation:
Add the two equations together. This cancels the x and gets us y=6
Then substitute y in more the first equation which gets us -8
Answer: y = 6 x = -8
Step-by-step explanation:
X+2Y=4
-X-Y=2
(Combine like terms)
Y= 6
(Plug in 6 for y)
X+2(6)=4
X+12=4
X= -8
2x2=4 because 2+2=4 and 2,4 bam got ur answer 4

The pie chart shows information about voters in an election. 3360
more women voted than men. Work out the total number of voters.
Answer:
4838 total number of voters
Step-by-step explanation:
In a whole circle there 360°, in a straight line theres 180°.
180-110=70 first to break it down to find the degrees of women.
180+70=250° for women.
250°=3360
we need to find 110° of men
25°=336
times 4
100°=1344
divide by 10
10°=134.4 round down 134
1344+134=1478
3360+1478=4838

Find the common difference of the arithmetic sequence 14,7,0 ....
Answer:
Step-by-step explanation:
the formula for common difference is
d = aₙ - aₙ₋₁
So,
d = a₂-a₁ = a₃-a₂
d =7-14 & d=0-7
d = -7 & d = -7
Consider the following work breakdown structure: Time Estimates (days) Activity Precedes Optimistic Most Likely Pessimistic Start A,B - - - A C,D 44 50 56 B D 45 60 75 C E 42 45 48 D F 31 40 49 E F 27 36 39 F End 58 70 82 What is the probability that the critical path for this project will be completed within 210 days
Answer: the probability that the critical path for this project will be completed within 210 days is 0.99725
Step-by-step explanation:
Given that;
Work break down is;
Time Estimates (days)
Activity Precedes Optimistic Most Likely Pessimistic
Start A,B - - -
A C,D 44 50 56
B D 45 60 75
C E 42 45 48
D F 31 40 49
E F 27 36 39
F End 58 70 82
we know that;
Expected Time = ( Optimistic Time + ( 4 × most likely time) + pessimistic time) / 6
and
Variance = [( pessimistic time - Optimistic time) / 6 ]²
so
ACTIVITY EXPECTED TIME VARIANCE
A (44 + (4 × 50) + 56) / 6 = 50 ((56 - 44) / 6)² = 4
B (45 + (4 × 60) + 75) / 6 = 60 ((75 - 45) / 6)² = 25
C (42 + (4 × 45) + 48) / 6 = 45 ((48 - 42) / 6)² = 1
D (31 + (4 * 40) + 49) / 6 = 40 ((49 - 31) / 6)² = 9
E (27 + (4 * 36) + 39) / 6 = 35 ((39 - 27) / 6)² = 4
F (58 + (4 * 70) + 82) / 6 = 70 ((82 - 58) / 6)² = 16
ACTIVITY DURATION ES EF LS LF SLACK
A 50 0 50 0 50 0
B 60 0 60 30 90 30
C 45 50 95 50 95 0
D 40 60 100 90 130 30
E 35 95 130 95 130 0
F 70 130 200 130 200 0
FORWARD PASS:
ES = MAXIMUM EF OF ALL PREDECESSOR ACTIVITIES; 0 IF NO PREDECESSORS ARE PRESENT.
EF = ES + DURATION OF THE ACTIVITY.
CRITICAL PATH = PATH WITH THE LONGEST COMBINED DURATION VALUE AND 0 SLACK.
CRITICAL PATH = ACEF
DURATION OF PROJECT = 200
Now the probability
VARIANCE OF CRITICAL PATH = SIGMA(VARIANCE OF THE CRITICAL PATH) = 25
STANDARD DEVIATION OF CRITICAL PATH = SQRT(VARIANCE OF CRITICAL PATH) = 5
EXPECTED TIME = DURATION OF THE PROJECT = CRITICAL PATH = 200
DUE TIME = 210
Z = (DUE TIME - EXPECTED TIME) / STANDARD DEVIATION OF CRITICAL PATH)
Z = (210 - 200) / 5 = 2
Now form the Normal Distribution Table;
Z = 0.99725
Therefore, the probability that the critical path for this project will be completed within 210 days is 0.99725
What is the constant of proportionality for the relationship shown in the table? x 2 4 6 8 y 1 2 3 4
1/2
2
or not proportional
Answer:
1/2
Step-by-step explanation:
Given
x 2 4 6 8
y 1 2 3 4
Required
Determine the constant of proportionality (k)
The relationship between x and y is:
[tex]y = kx[/tex]
When y = 2, x = 4;
So, we have:
[tex]2 = k * 4[/tex]
[tex]2 = 4k[/tex]
[tex]4k = 2[/tex]
Make k the subject
[tex]k = \frac{2}{4}[/tex]
[tex]k = \frac{1}{2}[/tex]
Hence, the constant of proportionality is 1/2
