Answer: The expression would be 2b+7
Step-by-step explanation:
b will be the number of blue beads for the bracelet.
The number of red beads will be represented as b + 7.
Determine the expression for the total number of beads.
Then we can written it as,
= b + (b +7)
= 2b + 7.

Use the equation below to find v, if u=17, a=4, and t=8. 4=u+at
Answer:
This is not a valid equation, as the left-hand side is not equal to the right-hand side.
Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.
Step-by-step explanation:
The given equation is:
4 = u + at
where u = 17, a = 4, and t = 8.
Substituting the given values, we get:
4 = 17 + 4(8)
Simplifying the right-hand side:
4 = 17 + 32
Combining like terms:
4 = 49
This is not a valid equation, as the left-hand side is not equal to the right-hand side.
Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.
A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Lauren has a points card for a movie theater.
She receives 60 rewards points just for signing up.
She earns 5.5 points for each visit to the movie theater.
She needs 104 points for a free movie ticket.
Write and solve an equation which can be used to determine xx, the number of visits Lauren must make to earn a free movie ticket.
Multiply points per visit x number of visits, using x for the number of visits:
5.5x
Add that to the points she already has:
5.5x + 60
This needs to equal a total of 104 points:
5.5x + 60 = 104
Now solve for x
5.5x + 60 = 104
Subtract 60 from both sides
5.5x = 44
Divide both sides by 5.5
X = 8
She needs 8 more visits

Show work to find the solution for the system:
y = 3x + 5
12x - 4y = -20
Answer: Infinitely many solutions
The solutions are of the form (x,y) = (x,3x+5) for any real number x.
========================================================
Explanation:
Plug the first equation into the second. We'll replace y with 3x+5
12x-4y = -20
12x-4( y ) = -20
12x-4(3x+5) = -20 .... y replaced with 3x+5
12x-12x-20 = -20
0x-20 = -20
0-20 = -20
-20 = -20
We end up with a true equation no matter what x is.
Therefore, this system has infinitely many solutions.
Each solution is of the form (x,y) = (x,3x+5) because y = 3x+5.
Answer:
Infinently Many solutions!
Any number would work.

What is the recursive formula for the geometric sequence with this explicit formula? an=6*(-1/4)^(n-1)
Answer:
A
Step-by-step explanation:
The explicit formula for a geometric sequence is
\(a_{n}\) = a₁\((r)^{n-1}\)
where a₁ is the first term and r the common ratio
Given the explicit formula
\(a_{n}\) = 6\((-\frac{1}{4}) ^{n-1}\)
where a₁ = 6 and r = - \(\frac{1}{4}\)
A recursive formula allows any term in the sequence to be found by multiplying the previous term by r , thus
\(a_{n}\) = \(a_{n-1}\) (- \(\frac{1}{4})\) with a₁ = 6 → A

Play soccer: _________67% / 33% / 100%
Do not play soccer:___ 45% / 55% / 100%
Total : _____________112% / 88% / 200%
Step-by-step explanation:
play soccer: total is 90, to find percentage :
60/90 = 0.6666666667 estimated = 0.67
0.67 x 100 = 67%
30/90 = 0.3333333333 estimated = 0.33
0.33 x 100= 33%
33% + 67% = 100%
don’t play soccer : total is 60, to find percentage:
27/60 = 0.45
0.45 x 100 = 45%
33/60= 0.55
0.55 x 100 = 55%
45% + 55% = 100%
Total for first column going down
67% + 45% = 112%
Second column going down
33% + 55%= 88%
Third column going down
100% + 100% = 200%
Third column going across
112% + 88%= 200%
Play soccer: 67% / 33% / 100%
