You take that -2y over under the 3y and you add them and you get 5y and then u say 8+5y=-2 and then you bring the -2 over under the 8 and you get 10 and there you have it it now is 10+5y. Hope that was helpful

This seems like a lot more work than it is, but here we go
Simplifying<span>8 + -2y = 3y + -2 
 Reorder the terms: 8 + -2y = -2 + 3y 
 Solving 8 + -2y = -2 + 3y Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right.
  Add '-3y' to each side of the equation. 8 + -2y + -3y = -2 + 3y + -3y Combine like terms: -2y + -3y = -5y 8 + -5y = -2 + 3y + -3y 
 Combine like terms: 3y + -3y = 0 8 + -5y = -2 + 0 8 + -5y = -2 Add '-8' to each side of the equation. 8 + -8 + -5y = -2 + -8 
 Combine like terms: 8 + -8 = 0 0 + -5y = -2 + -8 -5y = -2 + -8 Combine like terms: -2 + -8 = -10 -5y = -10
  Divide each side by '-5'. y = 2 
 Simplifying y = 2</span><span>

Will give brainliest to whoever answers both questions!! I need to turn this in soon!
Harman [31]

Answer:

y=55x

given y=385

x=gallons of gas = 385/55 = 7 gallons

inverse function

y=55x

change x to y and y to x

x=55y

y=x/55

inverse function is x/55

aev [14]

Answer:

The number of men was 80

The number of women was 70

Step-by-step explanation:

The question in English is

Having organized a bingo has raised $1900. For the entrance of men $15 and women $10 and an attendance of 150 people has been reported. Determine the number of men and the number of women who participated in the bingo.

Let

x----> the number of men

y----> the number of women

we know that

x+y=150

x=150-y -----> equation A

15x+10y=1,900 -----> equation B

substitute equation A in equation B and solve for y

15(150-y)+10y=1,900

2,250-15y+10y=1,900

15y-10y=2,250-1,900

5y=350

y=70

Find the value of x

x=150-70=80

therefore

The number of men was 80

The number of women was 70

Given the parabola whose equation is , find the focus and determine if the parabola opens up or down.
ziro4ka [17]
The equation of a parabola is:
y = ax {}^{2}  + bx + c
If a>0, then the parabola opens up;
If a<0, then the parabola opens down.
The coordinates of focus are:
( -  \frac{b}{2a}  \:  \:   \frac{1 - b {}^{2}  + 4ac}{4a} )
