3y-3.5/3y+6=17/25.5. find the value of y. give the scale factor of the polygon
Mekhanik [1.2K]

Hi the answer to your question is

 

((3y - 3.5) / (3y + 6)) * 25.5 = (17 / 25.5) * 25.5

((3y - 3.5) / (3y + 6)) * 25.5 = 17 (76.5y - 89.25) / (3y + 6) = 17

((76.5y - 89.25) / (3y + 6)) * (3y + 6) = 17 * (3y + 6) 76.5y - 89.25 = 51y + 102 76.5y - 51y = 102 + 89.25

25.5y = 191.25

y = 191.25 / 25.5

WILL GIVE BRAINLIEST

Answer:

The correct option is A.

Step-by-step explanation:

If a line passes through two points (x_1,y_1) and (x_2,y_2), then the equation of line is

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Let y be the profit (in millions) after x years.

From the given graph it is clear that the line passes through the point (1,-100).

The company paid for these costs and made combined profits of $80 million after 4 years. It means the graph passes through the point (4,80).

The line passes through (1,-100) and (4,80). So, the equation of line is

y-(-100)=\frac{80-(-100)}{4-1}(x-1)

y+100=\frac{180}{3}(x-1)

y+100=60(x-1)

y+100=60x-60

Subtract 100 from both sides.

y+100-100=60x-60-100

y=60x-160

The function form is

f(x)=60x-160

Therefore, the correct option is A.
