Find the rate of change of the linear function
shown in the graph. Then find the initial value.
Answers
Answer:
4 ; Initial value is (- 1)
Step-by-step explanation:
The rate of change of a linear function is slope of the line.
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
(0, - 1)
(1, 3)
m = [tex]\frac{-1-3}{0-1}[/tex] = 4
Initial value is - 1
y = 4x - 1
The equation of the graph is y = 4x - 1 with a rate of change of 4. The initial value of the function is y = -1.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
As per the given graph,
The rate of change or slope of a function is the ratio of the difference of y's and x's coordinates.
Therefore, let's consider two points (0,-1) and (1,3)
Slope = (3 - (-1))/(1 - 0)
Slope = 4
The y-intercept is -1 so the equation will be y = 4x - 1.
The initial value of function at x = 0 is y = 4(0) - 1 = -1.
Hence "The equation of the graph is y = 4x - 1 with a rate of change of 4. The initial value of the function is y = -1".

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.

Answers
[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.

Equal to.
Step-by-step explanation:
The easiest way to figure this out is to convert 14,400 seconds to hours. There are 60 seconds in a minute and 60 minutes in an hour. So, divide 14,400/60, which is 240. This is now 240 minutes. To figure out minutes into hours, divide 240/60, which is 4. 4=4, so 4 hours equals 14,400 seconds.

opportunity cost
The actions that cannot be taken as a result of an action that is taken are known as the opportunity cost of the actions taken.
What is the opportunity cost?" he opportunity cost of a particular activity option is the loss of value or benefit that would be incurred by engaging in that activity, relative to engaging in an alternative activity offering a higher return in value or benefit."
Let say, a homeless man has only $8. He is hungry and don't have cloths to wear. Now, if he buys a burger and some chocolates with all the money he has, then he cannot use that money to buy anything else.
Therefore, he will not be able to buy any cloth as he spent his money on food. If there is any t-shirt available at the same cost, then the cloth is the opportunity cost.
Therefore, the actions that cannot be taken as a result of an action that is taken are known as the opportunity cost of the actions taken.

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
Answers
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.

Answer: x= -10
Step-by-step explanation:
Let's solve your equation step-by-step.
6x−9=8x+11
Step 1: Subtract 8x from both sides.
6x−9−8x=8x+11−8x
−2x−9=11
Step 2: Add 9 to both sides.
−2x−9+9=11+9
−2x=20
Step 3: Divide both sides by -2.
−2x /-2= 20/-2
x=−10
Answer:
x=−10
