-8>4+2v
How do you do this

Answers

Answer:

Step-by-step explanation:

-8 > 4 +2v ; subtract 4 from both sides

-8-4 > 4-4 +2v; calculate

-12 > 2v; divide both sides by 2

-6 > v

TO Know:

apply the same operation to both sides of inequality

if the operation is dividing or multiplying by a negative number change the direction of the inequality

PLEASE HURRY WILL GIVE BRAINLIST ​

Answers

Answer:

x = 51

Step-by-step explanation:

x = 180 - (2x - 8) - (180 - 153)

x = 180 - 2x + 8 - 27

3x = 180 - 27

3x = 153

x = 51

Answer:

Step-by-step explanation:

2x-8 + x =153

Sam decided to go to the amusement with his sister. He paid $10 for parking and $12.50 per ticket. Determine the y-intercept. Write your answer as an ordered pair (x,y).

Answers

Answer:

[tex]y= 10+12.5x[/tex]

Step-by-step explanation:

Given data

He paid $10 for parking and

$12.50 per ticket.

let the number of tickets be x

and let the total cost be y

Hence the expression in terms of x and y is

[tex]y= 10+12.5x[/tex]

Jeri has a total of 40 pets with a total of 160 legs. If
she owns only cats and dogs, how many of each does
she have? Write a system of equations to represent
this situation. Solve it using any method.

Answers

Answer:

let x be the number of cats and y be the number of dogs:

x + y = 40

4x + 4y = 160

If you divide both sides of the second equation by 4, you will be left with:

x + y = 40

Then, subtract both equations:

x + y =40

- (x + y = 40)

0 = 0

Since you have a number = a number, there are infinite solutions.

in the 3rd century bc the egyptians used their body parts to measure things.Why do you think peoplebinvented measurement system if body parts can be used to measure?


PLEASE ANSWER IT I REALLY NEED THANKYOU ​

Answers

In order to have an accurate measurement system, humans would’ve had to have created one. Although body parts could be used to measure things, the lengths would’ve been different everytime. This is because no human’s body part is the exact same length as another’s. Everybody’s bone structure is different so in order to create a universally correct measurement system, humans had to invent a new one.

4. Determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
Write yes or no and explain your reasoning by showing work.

Answers

Answer:

YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Step-by-step explanation:

Given

Given that the function f(x) and g(x) are inverse functions.

[tex]f\left(x\right)\:=\:\frac{1}{3}x\:+\:5[/tex]

[tex]g(x) = 3x - 15[/tex]

To determine

Let us determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Determining the inverse function of f(x)

A function g is the inverse function of f if for y = f(x), x = g(y)

[tex]y=\frac{1}{3}x+5[/tex]

Replace x with y

[tex]x=\frac{1}{3}y+5[/tex]

Solve for y

[tex]y=3x-15[/tex]

Therefore,

YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
