Answer:

the function y – 2 = –5(x – 2) is linear.

Step-by-step explanation:

We need to find the correct option from provided options which represents a linear function

Since, the linear equation is in the form of <u>y=mx+c </u>where m is slope of line.

In first part y – 2 = –5(x – 2)

Simplify, the function

y -2 = -5x + 10

Add both the sides by 2, in above equation

y = -5x +12

This function is in the form of y=mx+c

so, this is a linear function

In second part x + 7 = –4(x + 8)

Simplify, the function

x+7= -4x+32

subtract both the sides by 7, in above expression

x= -4x+32-7

x= -4x+25

add both the sides by 4x,

x +4x= 25

5x= 25

divide both the sides by 5,

x =5

This is not in the form of y=mx+c

so, this is not a linear function

In third part y – 3 = y(x + 4)

Simplify, the function

y-3= yx+4y

add both the sides by 3,

y= yx+4y+3

This is not in the form of y=mx+c

so, this is not a linear function

In fourth part y + 9 = x(x - 1)

Simplify, the function

y+9= x^{2}-x

subtract both the sides by 9,

y= x^{2}-x-9

This is not in the form of y=mx+c

so, this is not a linear function

Therefore, the function y – 2 = –5(x – 2) is linear.

Which value is a solution to the inequality 2x − 5 &lt; −12?
aleksandr82 [10.1K]
The correct answer would be -4

explanation:
2x-5<-12, add 5 to both sides so then you get 2x<-8, then divide by two, x<-4.

PLEASE HELP! WIL GIVE BRAINLLIEST!
yarga [219]

Answer:

First Graph is Correct

Step-by-step explanation:

We are given the inequality:

n \leq 46

This means any number EQUAL TO or LESS than 46

Since, we have "equal to", there should be a "closed" circle on 46 (it means 46 is included).

LESS THAN means all numbers to the "LEFT".

Looking at the 4 number lines, we can eliminate last 2 choices since they don't have closed circles.

As for the first two choices, the first choice is correct because it shows us all the numbers left of 46 and 46 included (signified by the closed circle).

So, the first number line is the solution

atroni [7]

Answer:

The answer would be 0.2%

Step-by-step explanation:

There's 52 cards in a standard deck of cards and a set of 4 for each different symbol. 100% of the deck would be 52 cards and each deck has 4 suits and each suite has 13 cards and 75% of the cards aren't the diamond Linda is looking for so it would be a slim to none chance on pulling a diamond out of the deck and shuffling the deck each time makes it worse so it gives her like a 0.2% chance of pulling a diamond.

Hope this helps :))
