the cost (in dollars) of a custom made t shirt is represented by 0.75n + 9.99, where n is the number of words in the design. write and interpret a simplified expression that represents the cost of 12 t shirts

t=9.48n+119.88

Step-by-step explanation:

where t is the total cost of 12 t-shirts, and n is the number of words in the design

0.75n+9.99 is the equation for custom made t-shirts, and n represents the number of words in the design

t=12(0.75n+9.99)

where t is the total cost of t-shirts, and n is the number of words in the design

When simplified, this becomes t=9.48n+119.88

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
