At a portrait studio, three 8-inch-by-10-inch pictures and two 5-inch-by-7-inch pictures cost a total of $52. Two 8-inch-by-10-inch pictures and two 5-inch-by-7-
inch pictures cost a total of $40. This situation can be represented by the system
of equations, where x is the cost in dollars of each 8-inch-by-10-inch picture and
y is the cost in dollars of each 5-inch-by-7-inch picture.

What is the cost of one 5-inch-by-7-inch picture?

$18 was the price of the t-shirt

step-by-step explanation:

the monthly balance will be $75,000

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
