elograms in an art piece and determines that there are altogether 42 triangles and
parallelograms. if there are 150 total sides, how many triangles and parallelogia

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

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75

17,000 is the correct answer.

the answer, i believe is y-8=1(x+4)
