To make I a subject of the formula V = IR, we *
subtract R from both sides
multiply both sides by R
divide both sides by R
divide both sides by I
The original
Equation is V = IR
Where I is multiplied by R
To solve for I you need to isolate it by dividing both sides by R
I = V/ R
Answer: divide both sides by R
Answer:
To make I a subject of the formula V = IR, we divide both sides by R.
Step-by-step explanation:
V = IR
V/R =IR/R
The R in IR/R cancels out because it is on the other side.
We then have:
V/R = I
Which can be written as:
I = V/R

Which of the following rational functions is graphed below?
Considering the asymptotes, the rational function given below is the following:
B. [tex]f(x) = \frac{1}{x(x + 2)}[/tex]
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the vertical asymptotes are x = 0 and x = -2, hence the denominator is given by:
x(x + 2).
The function has no x-intercepts, hence the numerator is of 1. So the function is given by:
B. [tex]f(x) = \frac{1}{x(x + 2)}[/tex]

Ricardo is creating a budget for himself to set goals on how much money he wants to save. At his current job, he makes $300 per week, and spends $40 each week on his expenses. If he wants to save a total of at least $2,600, how many weeks at minimum does he have to work for in order to reach his goal?
Answer:
10 Weeks
Step-by-step explanation:
If he makes $300 every week minus $40 for his expenses and needs $1200. 300-40=260..... 260x10=1200 So he would have to work 10 weeks at a minimum.
The number of weeks at minimum does he have to work for in order to reach his goal is 10 weeks.
What is unitary method?The unitary method is used to find the value of a single unit from a given multiple.
For example, the price of 40 pens is Rs. 400
It should be noted that the concept of ratio and proportion is used for problems related to this method.
According to questions,
He makes $300 per week
and spends $40 each week on his expenses.
Therefore his total savings per week = $300 - $40
= $260.
Also he wants to save a total of at least $2,600.
Thus number of weeks at minimum does he have to work for in order to reach his goal = $2600 ÷ $260
= 10 weeks.
Hence the required number of weeks = 10 weeks.

A two-digit number is 5 times the sum of its digits. If 9 is added to the number, its digits are reversed. Find the number
Answer:
The number = 45
Step-by-step explanation:
Let the 10s digit = x
Let the units digit = y
10*x + y = 5(x + y) Start here: remove the brackets
10*x + y + 9 = 10y + x Subtract y and 10x from both sides
Using the first equation
10x + y = 5x + 5y
5x + y - 5y = 0
5x - 4y = 0
5x = 4y
y = 5/4x
From the second equation
9 = 9y - 9x
1 = y - x Substitute y = 5/4 x
1 = 5/4x - x
1 = 1/4 x
x = 4
y = 5/4 * 4
y = 5.

Question 4 (2 points)
Answer:
kiran will take 48 minutes 16 x 3
mai will take 36 minuttes 13 x 3
Step-by-step explanation:
(1) Kiran will take 48 minutes to reach the end of a 12-mile bike path.
(2) Mai will take 36 minutes to reach the end of a 12-mile bike path.
What is ratio?Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Kiran rides 4 miles every 16 minutes.
Also, Mai rides 4 miles every 12 minutes.
To find the time taken by Kiran and Mai to reach 12 mile bike paths,
Use ratio property,
Time taken by Kiran to ride 4 miles = 16 minutes,
For 1 mile = 4 minutes,
For 12 miles = 12 x 4 = 48 minutes
Time taken by Mai to ride 4 miles = 12 minutes,
For 1 mile = 3 minutes
For 12 miles = 12 x 3 = 36 minutes.
Kiran will take 48 minutes and Mai will take 36 minutes to reach the end of a 12-mile bike bath.

Ms. Green and Mr. White took their science classes to the museum. Ms. Green spent $262 to
buy 28 student tickets and 4 adult tickets for her class. Mr. White spent $191 for 22 student
tickets and 2 adult tickets for his class.
The price of student's ticket will be $7.5 while on the other hand, the price of adult's ticket will be $13.
Based on the information given, the equations to solve the question will be:
28s + 4a = 262 ....... i
22s + 2a = 191 ....... ii
Multiply equation i by 2
Multiply equation ii by 4
56s + 8a = 524
88s + 8a = 764
Subtract the equations above
32s = 240
s = 240/32 = 7.5
Student's tickets = $7.5
Adult's ticket will be:
22s + 2a = 191 .
22(7.5) + 2a = 191
165 + 2a = 191
