(1) given the linear equation,
y = -3x + 1 identify the initial value and the rate of change

(2) dani's estimate for the cost of tiling her bathroom floor is $100 plus $5 per square foot.

write an equation to represent this linear function.

Step-by-step explanation:

put x=0

y=-3*0+1=1

initial value=1

rate of change=-3

y=5x+100

where x is number of square feet.

y=cost of tiling.

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
