Valentina is cutting three different-sized circular mirrors to fit in a piece of art. The radius of the medium-sized mirror will be 40% larger than the radius of the smallest mirror, and the radius of the largest mirror will be 40% larger than the radius of the medium-sized mirror. If the radius of the smallest mirror is 1/2 foot, what will be the area, in square feet, of the largest mirror? A 2.5 B 3.0 C 5.3 D 6.2

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
