Answer:
A: $45 for 3 days
B: c=d(15)
Step-by-step explanation:
A: If 105 is the cost for 7 days and we want to find the cost for only 3 we have to find the cost for one day to start with so, 105 divided by 7 which is $15 so its 15 dollars a day then you multiply 15 by the number of days we want (3) and you get $45.
8m + 34 = 10 - 16m
How do I do?
Answer:
m=-1
Step-by-step explanation:
8m + 34 = 10 - 16m
fist add 16m to each side
8m+16m+34=10
then subtract 34 from each side
8m+16m=10-34
add like terms
24m=-24
divide both sides by 24
m=-1
Write down the gradient of the line
(1 Point)
y=1/2x
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The equation of a line in point- slope form is
y = mx + c ( m is the slope ( gradient ), c is the y- intercept )
y = [tex]\frac{1}{2}[/tex] x ← is in point- slope firm
with gradient = [tex]\frac{1}{2}[/tex]

Usually, such questions arise in the context of arithmetic or geometric sequences.
Arithmetic sequence
The explicit formula for an arithmetic sequence has the general form ...
a(n) = a(1) +d(n -1) . . . . . . . first term a(1); common difference d
The recursive formula for the same arithmetic sequence will look like ...
a(1) = a(1) . . . . . . . the first term is the first term
a(n) = a(n-1) +d . . . the successive terms are found by adding the common difference to the term before
__
Note: The explicit formula may be given as the linear equation a(n) = dn +b. Then the first term is a(1) = d+b.
__
Geometric sequence
The explicit formula of a geometric sequence has the general form ...
a(n) = a(1)·r^(n -1) . . . . . . first term a(1); common ratio r
The recursive formula for the same geometric sequence will be ...
a(1) = a(1) . . . . . . the first term is the first term
a(n) = a(n-1)·r . . . the successive terms are found by multiplying the term before by the common ratio
__
Note: The explicit formula may be given as the exponential equation a(n) = k·r^n. Then the first term is a(1) = kr.
__
Other sequences
Suppose you're given the quadratic sequence ...
a(n) = pn^2 +qn +r
Since the sequence is known to be quadratic (polynomial degree 2), we expect that we will only need the two previous terms a(n-1) and a(n-2). Effectively, we want to solve ...
a(n) = c·a(n-1) +d·a(n-2) +e
for the values c, d, and e. Doing that, we find ...
(c, d, e) = (2, -1, 2p)
So, the recursive relation is ...
a(1) = p +q +r
a(2) = 4p +2q +r
a(n) = 2a(n-1) -a(n-2) +2p
__
Additional comment
The basic idea is to write the expression for a(n) in terms of terms a(n-1), a(n-2) and so on. That will be easier for polynomial sequences than for sequences of arbitrary form.
There are some known translations between explicit and recursive formulas for different kinds of sequences, as we have shown above. If you recognize the sequence you have as being of a form with a known translation, then you would make use of that known translation. (For example, Fibonacci-like sequences are originally defined as recursive, but have explicit formulas of a somewhat complicated nature. If you recognize the form, translation from the explicit formula may be easy. If you must derive the recursive relation from the explicit formula, you may be in for a lot of work.)

0.2(3b)+0.2(−15c)=
0.6b−3c
Answer:
0.6b-3c
Explination:

we can use dispributive property because of the parentheses
by distributing 0.2 to 3b and -15c
we get 0.6b and -3c
you could be thinking why did the numbers shrink?
the numbers decrease because every time you multiply by a decimal the number decreases

Michael bought a guitar that was on sale for 15% off the regular price of $200. The total cost included 8% sales tax. What was the total cost?
Answer:
$183.60
Step-by-step explanation:
Take the regular price and find the 15% discount:
200 x 0.15 = 30
Subtract the discounted amount from the original price:
200 - 30 = 170
Take the new price and find the sales tax:
170 x 0.08 = 13.60
Add the sales tax to the discounted price:
170 + 13.60 = 183.60

A family's home is currently worth $1,553,426, which is 70% higher than the home was
worth when they bought it. What was the value of the home when they bought it?
Answer:
The value of home when bought was $913,780.
Step-by-step explanation:
Given that:
Current worth of the house = $1,553,426
This is 70% more than the original worth of the house.
Let,
100 be the original percent and x be the original worth
Percent increase = (100+70)% = 170%
170% of x = $1,553,426
[tex]\frac{170}{100}x=1553426[/tex]
1.7x = 1553426
Dividing both sides by 1.7
[tex]\frac{1.7x}{1.7}=\frac{1553426}{1.7}\\x= 913780[/tex]
Hence,
The value of home when bought was $913,780.

(91+5) +(31-6)=?
Thanks
Answer:
121
Step-by-step explanation:
96+25=121
Answer:
121
Step-by-step explanation:
(91+5) + (31-6) = ?
The first step is to solve what's in the parenthesis.
91 + 5 = 96
31 - 6 = 25
(96) + (25) =
96 + 25 = 121
(91+5) + (31-6) = 121
Therefore, the correct answer is 121.

a bus accelerates from 2 m/s to 10 m/s in 5 seconds. What was its average acceleration?
Please Help
Answer:
I believe the answer is 4. Please correct me if I’m wrong.
Step-by-step explanation:
================================================
Work Shown:
A = old velocity = 2 m/s
B = new velocity = 10 m/s
C = change in time = 5 seconds
D = average acceleration
D = (change in velocity)/(change in time)
D = (B-A)/C
D = (10-2)/5
D = 8/5
D = 1.6 m/s^2
The acceleration 1.6 m/s^2 means that the velocity is increasing by 1.6 m/s for every second.

The price p of a pizza is $6.95 plus $0.95 per topping t on the pizza, write a function rule
Answer:
y= 6.95+0.95t
Step-by-step explanation:
Given data
The price p of a pizza is $6.95
plus $0.95 per topping
let the number of toppings be t
and let the total cost be y
Hence for any number of topping t the cost function is
[tex]y= 6.95+0.95t[/tex]
The function rule for the prize of a pizza is
[tex]P=0.95t +6.95[/tex]
Given :
The price p of a pizza is $6.95 plus $0.95 per topping t on the pizza
Initial price of the pizza is 6.95
The cost of each topping is 0.95 .
Let 't' be the number of toppings on the pizza
Price of a pizza = initial cost of pizza + cost per pizza ( number of toppings)
[tex]p=6.95 +0.95(t)\\P=0.95t +6.95[/tex]
The function rule for the prize of a pizza is
[tex]P=0.95t +6.95[/tex]

The CEO of a cell-phone company has recently noticed a 26% sales decrease in the month of July compared to June. Let n represent June’s sales. If y represents July’s sales, which equation can be used to determine the sales in July?
Answer:
y = n - 0.26n
y = 0.74n
Step-by-step explanation:
The equation that can be used to express the function above is given an Exponential Decrease function
Where:
y = a(1 - r)^t
Where
y = July sales
a = n = June sales
r = rate of decrease = 26% = 0.26
t = time in months = June to July = 1 month
t = 1
Hence, our equation =
y = n( 1 - 0.26)¹
y = n(1 - 0.26)
y = n - 0.26n
y = 0.74n
The equation that can be used to determine the sales in July is given as:
y = n - 0.26n
y = 0.74n
