Answer:

y = 2/7x +11

3x-4y = -24

Step-by-step explanation:

We would want to use substitute on the last set of equations since the first equation is already solved for y.  It is easy to substitute for y in the second equation

8-2y=3y-2<br> Help me please
lesya692 [45]
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>

Pls see attached question
zimovet [89]

Answer:

Step-by-step explanation:

put it on a coorinate grid,

circle circumference = 2*pi*r = 100.53

so the arc 19.2/100.53 = about 0.15 times the circumference of the circle

0.15*2pi = angle AOB in radians = 0.97

length DE is like 7.44

angle DOE is approx 0.485 radians beacuse it's half of angle AOB

area of shaded region is 804.2477 probably. I'm not sure about this last one sorry I think my calculator messed up
