Weegy solve the system of equations 2x+3y=40 and -2x+2y=20

Mathematics

prisoha [69]3 years ago
5 0

adding the 2 equations eliminates x and gives:-

5y = 60

y = 12

Plug y = 12 into the first equation:-

2x + 3(12) = 40

2x = 40 - 36 = 4 so x = 2

Answer is x = 2 and y = 12.

write a point-slope equation for the line that passes through the point (6,8) and is parallel to the line given by y=-5x+4
VashaNatasha [74]

Answer:

  y -8 = -5(x -6)

Step-by-step explanation:

The point-slope form of the equation for a line is generally written ...

  y -k = m(x -h)

for slope m and point (h, k).

The slope of your parallel line is the same as the slope of the reference line, -5. So your equation is ...

  y -8 = -5(x -6)
