Zhi bought 18 tickets for games at a fair. each game requires 3 tickets. zhi wrote the expression 18 – 3g to find the number of tickets she has left after playing g games. diego correctly wrote another expression, 3(6 – g), that will also find the number of tickets zhi has left after playing g games. use the drop-down menus to explain what each part of zhi's and diego's expressions mean.

Equation 1

18 represents the number of tickets Zhi starts with. -3 is how many tickets each game uses, G is the amount of games played.

Equation 2

This equation is just equation 1 in factored form, 3 times 6= 18 and                   -g times 3= -3g. All of the parts are the same from the first equation.

Hope this helps some!!

Step-by-step explanation:

89

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
