Answer: To write the equation in slope-intercept form, we need to isolate the y term on one side of the equation. We can do this by adding 4 to both sides of the equation:
y - 4 + 4 = x - 3 + 4
Combining like terms on each side, we get:
y = x - 3
This is the slope-intercept form of the equation. The slope of the line is 1, and the y-intercept is -3. The slope-intercept form of the equation is y = 1x - 3.
Answer: y = x + 1
Step-by-step explanation:
Write y - 4 =(x-3) in slope-intercept form
This is in Point Slope Form.
y - 4 =(x-3)
We add 4 to both sides
==> y - 4 + 4 = x-3 + 4
==> y = x + 1
This is slope intercept form, since it resembles the equation, y = mx + b, but m equals zero.

What is the probability that she chooses a fruit
snack, puts it back, and then chooses a granola
bar?
The probability of choosing a fruit snack replaced and then choosing a granola bar is 5/36.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, Mellisa has options to choose from 3 different snacks,
N(GB) = 4, N(C) = 3, and N(FS) = 5.
So, The sample space N(S) = N(GB) + N(C) + N(FS).
N(S) = 12.
The probability of choosing a fruit snack is,
P(FS)
= N(FS)/N(S).
= 5/12.
Given, She puts it back so replaced and hence the events are independent.
So, The probability of choosing a granola P(GB) = N(GB)/N(S).
= 4/12.
= 1/3.
Therefore The combined probability is (5/12)×(1/3).
= 5/36.

What is an equation of the line that passes through the point (6,1)(6,1) and is parallel to the line x+3y=15x+3y=15?
The equation of the line that passes through the point (6,1) and is parallel to the line x+3y=15 is 3y+x=9.
What is an equation of a line?The general equation of a straight line is given by the expression
y = mx + c, where m is the gradient and y = c is the point at which the line intersects the y-axis.
Given,
The line is parallel to the line x + 3y = 15 and passes through the point (6,1).
The procedures listed below can be used to find the equation of the line that runs parallel to the line x + 3y = 15 and passes through the point (6,1).
Step 1 - Keep in mind that two parallel lines have equal slopes.
Step 2: As a result, the line's slope across point (6,1) is -1/3.
Step 3: Accordingly, the equation of a line passing through the point (6,1) and being parallel to the line (x + 3y = 15) may be found using the one-point slope form of a line.
The one-point slope form is shown below in Step 4:
y-y₁=m(x-x₁)
Step 5: In the equation above, substitute the values of the known terms.
y-1=-(1/3)(x-6)
3y - 3 = -x + 6
3y +x = 9
Therefore, the equation of the line that passes through the point (6,1) and is parallel to the line x+3y=15 is 3y+x=9.

Total ways of required selection is 686, obtained from the sum of the cases of 3, 4 and 5 women in the committee.
What is defined as combination?Combinations are mathematical operations that count the variety of configurations that can be made from a set of objects, where the order of the selection is irrelevant. You can choose any combination of the things in combinations.
Given that 5 persons are to be selected with a condition of minimum 3 women. Therefore the different possibilities are:
1) 3 women and 2 men
2) 4 women and 1 man
3) 5 women
Final answer will be the sum of the above results.
Total ways to select 3 women from 6 women and 2 men from 8 men,
Total ways = ⁶C₃ * ⁸C₂
Similarly total ways for 4 women and 1 man = ⁶C₄ * ⁸C₁
Total ways for 5 women = ⁶C₅ * ⁸C₀
Add the three results to get the final answer,
Total number of ways = (⁶C₃ * ⁸C₂) + (⁶C₄ * ⁸C₁ ) + (⁶C₅ * ⁸C₀)

the hour property of the datetime structure stores the hour as an integer between 1 and 24. question 47 options: true false
False. The hour property of the datetime structure stores the hour as an integer between 0 and 23.
To support varied needs, three different property types are available:
1. Date — A day of the Gregorian calendar, without reference to a time zone or locale. The unit is a whole day, such as July 23, 2006.
2. Time of Day — A time of day, without reference to a time zone or locale. The unit is seconds, such as 15 seconds after 1:25 P.M.
3. Date Time — A date and time, stored internally to the millisecond if available, in a known time zone. For example 15.452 seconds after midnight on July 23, 2006 in London, U. K.
When presented with a DateTime value, a corresponding date and a time-of-day (in a specified time zone) can be determined.
However, the converse is not usually true: when starting with a Date and a TimeofDay value, multiple differing but "correct" DateTime values can be constructed, depending on assumptions about time zone, Daylight Savings Time, and other considerations. For example, when the date is January 1 in London, it can be December 31 in New York.

The inequality for the given situation is 25,000x-20,000,000≤5,000,000 and the solution for the obtained inequality is x≤1000.
Given that, it costs chevy $20,000,000 to develop and market a new model of cars.
What is gain or profit?The profit or gain is equal to the selling price minus the cost price. Loss is equal to the cost price minus the selling price.
Let the number of cars sold be x.
So, selling price of cars is $25,000x
Profit =Selling price-Cost price
⇒ 25,000x-20,000,000≤5,000,000
Solve the inequality
Add 20,000,000 on both the sides of an inequality, we get
25,000x≤25,000,000
⇒ x≤25,000,000/25,000
⇒ x≤1000

What is a complex number?A complex number is a number in the form z = x + iy where
x and y are real numbers and i = √(-1)How to find the complex number (25 + 22i)² in the simplest form?To find the complex number (25 + 22i)² in the form a + ib, we proceed as follws.
(25 + 22i)² = (25 + 22i)((25 + 22i)
Expanding the brackets, we have that
(25 + 22i)² = (25 + 22i)((25 + 22i)
(25 + 22i)² = [25 × 25 + 25 × 22i + 25 × 21 + (22i)²]
(25 + 22i)² = [625 + 550i + 550i + 484i²]
(25 + 22i)² = [625 + 550i + 550i + 484 × (-1)] Since i² = -1
(25 + 22i)² = [625 + 550i + 550i - 484]
Collecting like terms, we have that
(25 + 22i)² = [625 - 484 + 550i + 550i]
(25 + 22i)² = 141 + 1100i

For each and every natural number n, a statement, theorem, or formula can be proved using the mathematical induction technique. By generalizing this into the "Principle of Mathematical Induction," which we would utilize to demonstrate any mathematical assertion.
We are given a statement 1+3+5+. +(2n-1)=n^2
Now first let us prove the statement for n=1 where n is the number of terms
On the left hand side = 1

After solving the equation we know ABCD is a parallelogram.
What is parallelogram?
A parallelogram is a two-dimensional shape with four straight sides. All of the sides are equal in length and the opposite sides are parallel. Additionally, opposite angles are also equal. The shape is called a parallelogram because parallel lines are present on either side. Parallelograms can come in many different forms, such as rectangles and rhombuses. The properties of a parallelogram include the fact that the diagonal line that divides the parallelogram into two halves bisects the angles. Additionally, the cross product of the two diagonals is equal to the area of the parallelogram. Parallelograms are used in a variety of areas, including architecture, engineering, and mathematics. Depending on the application, parallelograms can be used to construct a variety of shapes, such as circles and ellipses.
