A charm bracelet costs $65, plus $25 for each charm, write an equation in standard form that represents the total cost y of a bracelet that has x charms please help!
Answer: , y = 65+25x
Step-by-step explanation:
Let x = Number of charms
Given : Fixed cost of bracelet = $65
On addition , cost per charm = $25
Total cost of bracelet = Fixed charge + (Charge per charm) x (number of charm)
If y= total cost.
Then, y = 65+25x , which is the required equation.
the answer would be (12)

How to find value of complex number from graph?
To find the value of a complex number from the graph, follow the steps below.
On the graph where x-axis represents the real line, the distance of the point give the real number.On the graph where y-axis represents the imaginary line, the distance of the point give the imaginary number, which is written with complex number i.The image shows w and z + w. The point w is 1 units left from the imaginary axis. Thus, the real number for w is -1.
This number is 2 units down. Thus, the complex number represent the point w is,
[tex]w=-1-2i[/tex] ......1
Similarly, z+w is 4 units left and 4 units up. Thus, the complex number represent z+w is,
[tex]z+w=-4+4i[/tex] ......2
Substrate equation 1 from equation 2,
[tex]z+w-w=-4+4i-(-1-2i)\\z=-4+4i+1+2i\\z=-3+6i[/tex]
Hence, In the image which shows the complex number w and z+w, the value of the complex number Z is -3+6i.

George had $127 in his checking account on Thursday. He got paid on Friday and deposited $130.00 into his checking account. Then on Saturday, he wrote two checks: one for $167.00 and one for $42.00. What is his checking account balance after writing the checks
Answer:
The balance on George's checking account is $48.
Step-by-step explanation:
To find the balance on George's checking account after writing the checks, you have to take the initial balance and add the amount he got paid and subtract the amounts of the checks he wrote:
Checking account balance=$127+$130-$167-$42
Checking account balance=$48
According to this, the answer is that the balance on George's checking account is $48.

The graphs of linear functions f and g are shown on the grid.
Which function is best represented by the graph of g?
A g(x) = f(x) − 4
B g(x) = 1/3 f(x)
C g(x) = f(x) − 2
D g(x) = 3f(x)
Answer:
b
Step-by-step explanation:
The function [tex]g(x)=\dfrac{1}{3}f(x)[/tex] is best represented by the graph of g. Option B is correct.
Given information:
From the given graph of functions f and g, it can be observed that the inclination of f is more than that of function g.
Inclination signifies the angle it makes with the x-axis and slope is the tan of inclination. Greater the value of the slope, greater will be the inclination.
From the graph, the slope of function f is more than the slope of function g. Functions f and g pass through the origin and they both are straight lines.
So, dividing the function f(x) by a constant will reduce the slope of the function g(x). So, the correct function should be [tex]g(x)=\dfrac{1}{3}f(x)[/tex].
Function g(x) = f(x) − 4 represents that the slope of f and g is same. So, it is incorrect.
Function g(x) = f(x) − 2 represents that the slope of f and g is same. So, it is incorrect.
Function g(x) = 3f(x) represents that the slope of g is three times that of f. So, it is incorrect.
Therefore, the function [tex]g(x)=\dfrac{1}{3}f(x)[/tex] is best represented by the graph of g. Option B is correct.

The smaller moon of Mars, Deimos, has a diameter of 7.5 miles. The larger moon, Phobos, has a diameter that is 1 3 4 times greater. What is the diameter of Phobos?
Answer: 13.125 miles.
Step-by-step explanation:
Given : The smaller moon of Mars, Deimos, has a diameter of 7.5 miles.
The larger moon, Phobos, has a diameter that is [tex]1\dfrac34[/tex] times greater.
Diameter of Phobos = [tex]1\dfrac34\times\text{(Diameter of Deimos )}[/tex]
[tex]=\dfrac{7}{4}\times7.5 \ \ \ [1\dfrac34 =\dfrac{7}{4}]\\\\=13.125\text{ miles}[/tex]
Hence, the diameter of Phobos = 13.125 miles.

Hours it takes Elena and Jada to meet: (2 points)
Answer:
The hours it takes Elena to meet Jada = 4 hours
Step-by-step explanation:
The distance between Elena and Jada = 32 miles
The speed with which Elena runs = 6 miles per hour
The speed with which Jada walks = 2 miles per hour
Let t, represent the time it takes until Elena and Jada meets, we have;
Distance = Speed × Time
The total distance covered by both Elena and Jada before they meet = The distance between them = 32 miles
The distance covered by Elena before meeting Jada = Elena's speed × The time that elapsed for them to meet
∴ The distance covered by Elena before meeting Jada = 6 mph × t
The distance covered by Jada before meeting Elena = Jada's speed × The time that elapsed for them to meet
∴ The distance covered by Jada before meeting Elena = 2 mph × t
The total distance covered by both Elena and Jada before they meet = The distance covered by Elena before meeting Jada + The distance covered by Jada before meeting Elena = 32 miles
∴ The total distance covered by both Elena and Jada before they meet = 6 mph × t + 2 mph × t = 32 miles
t × (6 mph + 2 mph) = 32 miles
t × 8 mph = t × 8 miles/hour = 32 miles
t = 32 miles/(8 miles/hour) = 4 hours
The time it takes until Elena and Jada meets = t = 4 hours

Find the 13th term in the following arithmetic sequence
2, 10, 18, 26, ...
Answer:
Find the 13th term in the following arithmetic sequence
2, 10, 18, 26 ...192 is the 13th term
Answer:
a(13) = 98
Step-by-step explanation:
a(n) = a1 + (n-1) d
a1 would be the original term, 2
since you are looking for the 13th term a(n) and n is 13
a(13) = 2 + (13-1) d
d would be the difference between each term, 8
a(13) = 2 + (13-1) 8
Now solve
a(13) = 2 + 12 * 8
a(13) = 2 + 96
a(13) = 98

Brooke needs a new computer. On Friday, the computer was $200.00. On Saturday, the price of the computer was $149.00. Determine if there was a markup or markdown and by what percent.
Answer:
Step-by-step explanation:
Given
price of the computer on Friday = $200
price of the computer on Saturday = $149
Difference in price = 200 - 149 = $51
Since the price reduces in price by $51, hence there was a markup in price.
% markup = difference in price/original price * 100%
% mark up = 51/200*100%
% markup = 51/2
% markup = 25.5%
Hence the markup was a 25.5% change
