A group of eight golfers paid $445 to play a round of golf. Of the golfers, one is a member of the club and seven are nonmembers. Another group of golfers consists of three members and two nonmembers. They paid a total of $195 . What is the cost for a member to play a round of golf, and what is the cost for a nonmember?
Answer:
the cost for a member to play a round of golf: $95
the cost for a nonmember: $50
Step-by-step explanation:
the cost for a member to play a round of golf: $x
the cost for a nonmember: $y
x+7y=445
x+2y=195
=> y=50, x=95
Answer:
member: $95, nonmember: $50

solve for W
14/W=26/39
Answer:
I think the answer is 21
Step-by-step explanation:
The answer is 21 because we can simple reduce 26/39 = 2/3. And now that you have done that all we need to do is find what 14/w = 2/3 this is quite simple as we just have to mutiply the 3*7 to get 21 as your answer. I don't know if this is correct or not but this is my best answer.
Answer:
21
Step-by-step explanation:
14 : w = 26 : 39
w = 14 * 39 : 26
w = 21

Determine whether each sequence is an arithmetic sequence. If yes, then state the common difference.
4, 7, 9, 11, 12,...
Answer:
Not arithmetic
Step-by-step explanation:
Arithmetic sequences go up by the same number or down by the same number.
From 4 to 7 thats up by 3
From 7 to 9 that's up by 2
Conclusion: not arithmetic
Answer:
The sequence is not an arithmetic sequence.
Step-by-step explanation:
4 is getting added by 3 to get 7
7 is getting added by 2 to get 9
9 is getting added by 2 to get 11
11 is getting added by 1 to get 12
As you can see, the sequence is not consistent. Therefore, it is not an arithmetic sequence.

Answer:
15
Step-by-step explanation:
f(x) = x^2+1
f(2) = 2^2+1 = 4+1 = 5
g(x) = 3x+1
g(3) = 3(3)+1 = 9+1 = 10
f(2)+g(3) = 5+10 =15
Answer:
15
Step-by-step explanation:
I'm just guessing though.
3^(2)+4(2)
4-9(5+1)+3
5^(2)+3^(2)-8
(3+2)^(2)+4(2+3)
8^(2)-9(2)+3
2(5)^(2)
4^(2)+6(2+8)
4+5(3)+2(7)-6
8+3(6)-3^(2)
2+6-5+4(6)
If h(x) = x2-5x + 7
find: h(2)
Answer:
h(2)= 1
Step-by-step explanation:
h(x) = x^2-5x+7
h(2) = 2^2-5*2+7
h(2)= 1
Answer:
1
Step-by-step explanation:
you have to substitute 2 were there's x in the function
h(2)=x^2-5x+7
=2^2-5(2)+7
=4-10+7
=1

Answer:
k > 24
Step-by-step explanation:
To solve an inequality you must isolate the variable. Do this by using the properties of equality, specifically the property of multiplication. To get k by itself multiply both sides by 4. This way k > 24. Then, you can check your answer by plugging in any number less than or equal to 24 and solving to see if it's true.
Answer:
k = 24
Step-by-step explanation:
k is greater than or equal to 24 and 4/4 = 1 so if k is greater than or equal to 24 than that could be 24/4 and that would equal 6. that is the answer to your question.

The domain is all of the x-values a function can have. The range is all of the y-values a function can have.
#50.
Domain: [-5, 10]
---The function starts at the x-value -5 and stops at the x-value 10.
Range: [-3, 5]
---The smallest y-value is -3 and the largest y-value is 5.
#51.
Domain: [-2, infinity)
---The function starts at the x-value -2 and has an arrow to indicate that it goes on forever.
Range: [0, infinity)
---The smallest y-value is 0 and an arrow indicates that the functions goes up and on forever.

Frederick used all his tiles to make a mosaic that was in the shape of a rhombus with a base of 10 inches and a height of 8 inches. Carrie has the same number of tiles as Frederick. She wants to use all of her tiles to make a mosaic in the shape of a parallelogram with a height of 5 inches. How long should she make the base of her mosaic?
Answer:
16 inStep-by-step explanation:
Both figures will have same area as same tiles used.
Area of rhombus:
A = ah = 10*8 = 80 in²Area of parallelogram:
a*5 = 80a = 80/5a = 16 in
