Proportional relationship:
y = kxUse a pair of points (0.14, 0.7) to find the value of k:
0.7 = 0.14kk = 0.7/0.14k = 5The function is:
y = 5xFill in the table:
x = 3.1 ⇒ y = 5*3.1 = 15.5x = 2.5 ⇒ y = 5*2.5 = 12.5x = 1.2 ⇒ y = 5*1.2 = 6x = 0.9 ⇒ y = 5*0.9 = 4.5y = 0.3 ⇒ x = 0.3/5 = 0.06y = 0.1 ⇒ x = 0.1/5 = 0.02Find the slope and y-intercept for this table.
Answer:
Slope is -5 and y-intercept is 90.
Step-by-step explanation:
Use the two values that you circles (4, 70) and (6, 60) .
slope (m) = the change in y-value/ (the change in the x-values).
m = (70 - 60)/(4 - 6) = 10/-2 = -5
The y-intercept is the value of "b" in the equation y = mx + b.
Using y = mx + b, substitute the value m and use point of your points (4, 70).
y = mx + b
70 = -5(4) + b Now solve for "b".
70 = -20 + b
+20 = +20
90 = b
Can you please help me with #4-#5?I don't know how to find the answer.
Answer:
Step-by-step explanation:
4:C(X) = 17x - 10, the first question wants you to find how much 5 ticket costs, so replace x with 5 so c(x)= 17(5)-10 which equals 75$
4a: 4a wants you to find how many tickets you can buy for 130$. So first replace the y or c(x) with 130 x, which gives 130=17x-10. Now we find x, first add 10 to both sides to cancel the -10, 140=17x, then divide 17 from both sides which gives 8.235, so we can buy 8 tickets.
4b: It is discreet because it cannot be broken down into decimals or fractions, since you cannot have a halve of a ticket.
4c: c(0) means the y-intercept
4d: the range is 7 to positive infinite

Answer:
The speed of the boat in still water is 12 miles per hour, while the speed of the current is 9 miles per hour.
Step-by-step explanation:
We'll use x as the speed of the boat in still water in miles per hour.
We'll use y as the speed of the current in miles per hour.
When the boat is traveling downstream, the speed of the boat is helped by the speed of the current and the net speed is x + y.
When the boat is traveling upstream, the current opposes the movement of the boat, and the net speed is x - y.
Using a table where d = distance in miles, r = rate or speed in miles per hour, and t = time in hours can help figure out how to figure out this problem.
─────────────────
Downstream│210│(x + y)│10
Upstream│210│(x - y)│70
─────────────────
Recall that distance = rate x time or d = rt.
210 = (x + y)10 ➤ Equation from downstream information.
210 = (x - y)70 ➤ Equation from downstream information.
210 = 10x + 10y ➤ Distribute.
210 = 70x - 70y ➤ Distribute.
7 × 210 = 7 × 10x + 7 × 10y ➤ Multiply the 1st equation by 7.
1470 = 70x + 70y ➤ Add the 1st equation to the 2nd.
210 =70x - 70y ➤ Add the 1st equation to the 2nd.
1680 = 140x
─────────────────
1680/140 = 140x/140
x = 12
210 = (12 + y)10 ➤ Substitute x = 12 into one of the original equations to find y.
210 = 120 + 10y
-120 - 120
90 = 10y
90/10 = 10y/10
y = 9
9 is 50% of what number plz help
Answer:
9 is 50% of number 18
'cuz u should do 18/2=9
Answer:
9 / 50% = Y / 100%
Solve for Y
50Y = 9 x 100
50Y = 900
Y = 900 /100 = 18
note: when i put / it means fraction
so the answer to your question is 18 :D
6t - 20 - 32u when t = 6 and u = 1/4
Answer: 8
Step-by-step explanation:
Substitute the variables for the number they represent
6(6) - 20 - 32(1/4)
Multiply
6*6 = 36
32 x .25 = 8
36-20-8
16-8
8
Answer:
here given equation is 6t - 20 - 32u
value of t=6
value of u=1/4
then...
putting the value in the given equation.. we get,
=6*6-20-32*(1/4)
=36-20-8
=8
1. y=3x+6 2. y=-2x+4 3. y=1/2x-6 4. y=2/3x 5. y=-4x+1/8

Step-by-step explanation:
steve baked 5 1/2 batches of cookies in one and one half hours. Vondra baked 3 1/3 batches of cookies in 11/12 hour. Which baker made cookies at a greater rate of batches per hour?
Answer:
Step-by-step explanation:
Steve 11/2 batches / 3/2 hrs = 11/2(2/3) = 11/3 = 3 2/3 = 3 22/33 batches/hr
Vondra 10/3 batches / 11/12 hr = 10/3(12/11) = 120/33 = 3 21/33 batches/hr
Steve had a very slightly faster batch rate by only 1/33 batch/hr
25. Abby won 57 points on her first turn in a game. She won 37 more
points on her second turn and then lost 19 points on her third turn.
She won some more points on her fourth turn. Now Abby has 100
points. How many points did she win on her fourth turn? Write an
equation using a variable for the unknown. Explain your thinking to a
friend.
Answer:
25 points
Step-by-step explanation:
57 + 37 - 19 + x = 100
94 - 19 + x = 100
75 + x = 100
x = 25
She won 25 points on her 4th turn.

hi guys can someone help me whit this question is for tommorow for my is so difficult . The exercise talks about math sets. It is: give three examples of sets A and B such that AU(union)B=B
Answer:
(i) A = {1}, B = {1, 2}, (ii) A = empty set, B = {1, 2, 3}, (iii) A = {a, b, c}, B = {a, b, c}, (iv) A = {7, 8, 9, 10}, B = {7, 8, 9, 10, 11, 12}
Step-by-step explanation:
The idea: A U B = the set of all elements (from a Universal set, like the set of all integers) that are in at least one of the sets A or B. So, for the equation A U B = B to be true, the set A must be a subset of the set B, because otherwise A U B would contain at least one element not in B, making the equation A U B = B false (set B would be a proper subset of A U B). So, if A = {1, 2, 3, 4} and B = {1, 2, 3}, then A U B = {1, 2, 3, 4}, and A U B = B would be false. However, if A = {1, 2, 3} and B = {1, 2, 3, 4}, then A U B = B would be true.

Y+12=y-20
Solve for y
Answer:
No solution
Step-by-step explanation:
y + 12 = y - 20
=> y = y - 20 - 12
=> y - y = -32
=> No solution

Answer:
1/2 = 0.5 and 3/4 = 0.75
Use a proportion: 0.5/2.60 = 0.75/x
Cross multiply: 0.5x = 0.75*2.60
So x = 0.75*2.60/0.5 = 3.90

PLEASE HELP!! QUESTION IS IN IMAGE
Answer:
false and then true
Step-by-step explanation:
Hope this helps :)
Answer:
First one is False, second one is true.
Step-by-step explanation:
For the first one, the left side of the equation would equal -6/3, and the left side would be 3/-6. When simplified it would be: -2 = -1/2, which is incorrect.
For the second one, the left side and the right side are the same because either way you put it, they are still being multiplied, and the order doesn't matter. The end result will be -72 = -72, which is correct.
I hope this helps!! :>
