Which expression makes the equation true for all values of x?
16x - 16 = 4( ? )
A 4x - 4
B 4x - 16
C 2x - 2
D 12x - 12
Answers
Answer:
A since if we multiply 4 × 4x, we get 16x, and 4 × 4, we get 16, which cancels with the other 16x - 16 on the left side. That makes sure that any x we choose will cancel out in the end.
Step-by-step explanation:
1. 16x - 16 = 4(4x-4)
2. 16x - 16 = 16x - 16
3. 0 = 0
4x16 - 16 = 48
16x4-16=48

Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

The table shows the balances of two bank accounts for 3 months. In what month will the balance of Account A be equal to the balance of Account B? I have a pic below
Answers
x can represent the number of months and y can represent the account balance
account a: y=35x + 150
this is because the balance starts at $150 and increases by $35 every month
account b: y=15x+450
this is because the balance starts at $450 and increases by $15 every month
now we use substitution (making equations equal to each other) to solve for x, the number of months it will take for the balances to be equal
35x+150=15x+450
-150 -150
35x=15x+300
-15x -15x
20x=300
/20 /20
x=15
On month 15, the balances of both accounts will be equal.

3) π
4) 1
5) y < 0
Step-by-step explanation:
1)
Cos
2)
The y-intercept is the value of y when x=0, ie the value of y when the line meets the y-axis. We can see from the graph that this is 1.
3)
The x-intercept is the value of x when y=0, ie the value of x when the line meets the x-axis. We can see from the graph that the smallest positive value of x when the line crosses the x-axis is π.
4)
Highest y value from graph is 1, and besides, for cos graphs, y≤1.
5)
We can see from the graph that between x=π and x=2π, the function is bellow the y-axis, ie y<0.
The graph is of a cos function. The y-intercept of the graph is the function value y=1. The smallest positive x-intercept of the graph is located at x=π. The greatest value of y is y=1, and it occurs when x=2π. For x between x = π and 2π, the function value y<0.
The point on the graph where it crosses the y-axis is known as the y-intercept. The y-intercept in this situation is zero since the graph crosses the y-axis at (0, 0).
The point at which the graph first crosses the x-axis at a positive value of x is known as the graph's smallest positive x-intercept. The graph in this instance crosses the x-axis at (x,0), making the smallest positive x-intercept.
The maximum value of the function is equal to the highest value of y. The greatest value of y in this situation is 1, and it happens when x = 2.
The function value y declines from 1 to 0 for x between x = and 2. You can observe this by examining the graph.

Step-by-step explanation:
The formula for the circumference of a circle is to multiply the radius (The line that's 3 ft in this case) by 2 and then multiply by π, which the problem says to substitute 3.14 in. Since the radius of this circle is 3, we multiply 2 by 3 and then multiply that by 3.14 to find our circumference. 3 * 2 = 6 and 6 * 3.14 = 18.84. The circumference of this circle is 18.84 ft.

Andy wants to rent a boat and spend at most $66. The boat costs $7 per hour, and Andy has a discount coupon for $4 off. What are the possible numbers of hours Andy could rent the boat? Use for the number of hours. Write your answer as an inequality solved for.
Answers
Answer:
h ≤ 10
Step-by-step explanation:
Let's first consider the cost of renting the boat without the discount. If Andy rents the boat for h hours, he will have to pay:
Cost = (price * time)
Cost = 7h
With the $4 discount, the cost of renting the boat for h hours will be:
Cost = (price * time) - discount
Cost = 7h - 4 .
We want to find the possible values of h such that the total cost of renting the boat is at most $66, which means:
7h - 4 ≤ 66
Step 1: To solve for h, we will add 4 to both sides of the inequality:
7h ≤ 70
Step 2: Finally, we will divide both sides by 7 to isolate h:
h ≤ 10
Therefore, Andy can rent the boat for at most 10 hours with his budget of $66 and the $4 discount coupon.
In inequality form, the solution is:
0 < h <= 10
Optional Step 3: We can try plug in 9 for h, 10 for h, and 11 for h to see how the inequality works:
9 for h:
7(9) - 4 ≤ 66
63 - 4 ≤ 66
59 ≤ 66
Thus, normally, the price to boat for 9 hours without the discount is $63, but with the $4 discount its now $59. $59 is less than $66 and allows Andy to not exceed his limit.
10 for h:
7(10) - 4 ≤ 66
70 - 4 ≤ 66
66 ≤ 66
Thus, normally, the price to boat for 10 hours without the discount is $70, but with the $4 discount its now $66. $66 is equal to $66 and is maximum amount Andy can spend to not exceed his limit.
11 for h:
7(11) - 4 ≤ 66
77 - 4 ≤ 66
73 ≤ 66
73 > 66
Thus, normally, the price to boat for 11 hours without the discount is $77, but with the $4 discount its now $73. $73 is greater than to $66 and causes Andy to exceed his limit since 11 is greater than 10.
