5x+8=4(3x+9) 5x+8=12x+36. 5x=12x+28

-7x=28. Divide both sides by -7 so x=-4

4y+8=4(2y-5). 4y+8=8y-20. 4y=8y-28

-4y=-28. Divide both sides by -4 so y=7

a storage jug was 4/5 full of water when did get indicated 72 what was the full capacity of the storage jug

IRISSAK [1]

Answer:

90. ( was the full capacity of jug)

to solve this 

firstly let the full capacity of jug 

 

be. x

so, 

4/5*x = 72

x = 72*5/4

x = 90

Which equation represents a linear function?

Mila [183]

The equation y - 2 = -5(x - 2) represents a linear function ⇒ 1st answer

Step-by-step explanation:

A linear function is any function that graphs to a straight line

(not a vertical line)

The forms of the linear equation are

y = m x + b, where m is the slope of the line which represents the function and b is the y-intercept ⇒ slope-intercept form
$y-y_{1}=m(x-x_{1})$ , where m is the slope and $(x_{1},y_{1})$ is a point lies on the line which represent the function ⇒ slope-point form
Ax + By = C, where A, B, and C are constant ⇒ standard form

Linear function means the greatest power x and y in the equation of the function is 1

∵ The equation is y - 2 = -5(x - 2)

∵ The greatest power of x and y is 1

∵ The equation is in the form of $y-y_{1}=m(x-x_{1})$ , where

m = -5 and the coordinates of the point are (2 , 2)

∴ The equation represents a linear function

The equation y - 2 = -5(x - 2) represents a linear function

You roll a number cube find the probability. P(3 or 4)

____ [38]

Say the cube has sides numbered 1-6 that means there are 6 possible outcomes. 3 and 4 are only two possible outcomes so the probability of that is 2:6. Simply 1:3 or 33%
