if y varies directly with x and x increases by 2 , is it possible to determine by how much y increases or decreases . yes or no and why
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
y ∝ x
y = kx
Where k is a constant and it can be any integer.
If y varies directly with x.
Yes, it is possible to determine by how much y increases or decreases as x increases.
If x increases by 2 then y also increases by 2.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
y varies directly with x.
This can be written as an equation,
y ∝ x
y = kx
Where k is a constant and it can be any integer.
Now,
If x increases by 2.
y = 2k
If k = positive integer
Then y will increase by 2k.
If k = negative integer
Then y will decrease by -2k
So,
Yes, it is possible to determine by how much y increases or decreases.
Thus,
If y varies directly with x.
Yes, it is possible to determine by how much y increases or decreases as x increases.

How many integers between 2020 and 2400 have four distinct digits arranged in increasing
order? (For example 2957 is one such integer)
(B) 10
(C) 15
(D) 21
e 28
Answer:
the answer is E
Step-by-step explanation:
We want to find how many integers are between 2020 and 2400 such that a criteria is meet, and the criteria is that the four digits are different and are arranged in increasing order.
We will see that there are 15 of these numbers between 2020 and 2400, so the correct option is C.
---------------------------
To count the number of digits that meet the given criteria, we first need to analyze how the criteria is.
If the numbers must be in increasing order, then the smallest number that can be in the hundreds place is 3 (the smaller integer larger than 2).
so we have:
23__
The number next to the 3 can be a 4, for example:
234_
And the final number can be any number larger than 4, so we have {5, 6, 7, 8, 9} a total of 5 options.
If instead of a 4, the number next to the 3 is a 5, we have:
235_
And the number next to the five can be any digit larger than 5, so now we have 4 options.
If instead of a 5, we have a 6, we will have 3 options to put after the 6.if instead of a 6, we have a 7, we will have 2 optionsif instead of a 7, we have an 8, we will have 1 option.Now, we can't have another number than a 3 in the hundreds place, because if we put a 4 there, we are out of the range, and 3 is the smallest digit that we can use there.
Then we already saw all the possible numbers that we can make, adding the numbers of options that we got above we will get:
5 + 4 + 3 + 2 + 1 = 15
This means that are 15 of these numbers between 2020 and 2400. Then the correct option is C.

A deck of cards contains 52 cards. These cards consist of four suits (hearts, spades, clubs, and diamonds) of each of the following 2.3.4.5, 6, 7, 8, 9, 10, jack,
queen, king, and ace. If a card is chosen from a deck of cards, find the probability of drawing a 6
The probability of drawing a 6 is
(Type a whole number or a simplified action.)
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Probabilities.
Here, In the game of cards, we have total number of 52 cards in a deck. Since here we have to find the probability of Card 6 from the whole deck.
Let's solve,
Total Number of Cards we have = 52
Total number of 6 numbered Cards in deck = 4
Hence, probability = Favourable Outcomes ÷ Total No. of Outcomes.
So, the Probability of getting a 6 Card = 4/52
= 1/13
Hence the probability is 1/13.

how do you solve for Y
problem #5
9514 1404 393
Answer:
y = 26
Step-by-step explanation:
You have already correctly solved for x, so you know that ...
m∠8 = 4(17)+10 = 78
Angle 12 is an alternate interior angle with respect to angle 8, so is congruent to angle 8.
m∠12 = m∠8
3y = 78
y = 78/3 . . . . divide by the coefficient of y
y = 26

slope= -4/0
how to find the slope from a table of data
The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is [tex]\frac{dy}{dx}[/tex] or:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Example:
Let's say you're give this table:
x: 1, 2
y: 1, 2
Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1
Do the same for x
Now plug the values taken in the slope formula and you get:
[tex]\frac{2 - 1}{2 - 1}[/tex]
[tex]\frac{1}{1} = 1[/tex]
Therefore the slope is 1.
Answer:
Rise/run
Rise over run.
Step-by-step explanation:
To find the slope pick two perfect spots on the line when the coordinates are not decimals.
Then, take those two points and figure out the distance. You will use rise/run.
so rise is how much you either go up or down and run is how much you either go right or left. so how much you'll go up or down? how much will you move right or left?
Lets say you have to go up 5 and then left 7 to get to the coordinate.
That's your slope! you went up so it's positive and you went left so it's negative. Rise over run : rise 5 left 7 so, 5 and -7 which is 5/-7 and that's your slope!

Answer:
y=-5/2x-4
