Camila has had a collection of sports cards for several years. If the time in years since the collection started is represented by t, and the number of cards in the collection is represented by B, match each of the statements below with an equation that models the function described. Camila had started her collection with 250 cards and her collection decreased by 60 cards each year. Camila didn't have any cards when she started her collection, but her collection grew by 60 cards each year.

1). 250 - 60t

2). 60t

Step-by-step explanation:

"Camila started her collection with 250 cards and decreased by 60 cards each year"

Starting number of cards with Camila = 250

Decrease in number of cards each year = 60

Decrease in number of cards after 't' years = 60t

Number of cards after 't' years = 250 - 60t

"Camila didn't have any card when she started her collection, but her collection grew by 60 cards each year."

Number of cards with Camila = 0

Number of cards grew each year = 60

Number of cards after 't' years = 60t + 0 = 60t

answer: the answer is ann

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
