Pop Quiz

math

1/5

Given the equation 10x + 2y - 5 = 0 Isolate y.

y = 5x - 2.5

y = 2.5 - 5x

y = 5 - 10x

Given the equation 10x + 2y - 5 = 0 Isolate y.

right answer

-y = -2 -3x

y = 5x

y = 2 + 3x

2/5

Given the equation 3x - y + 2 = 0 Isolate y.

Given the equation 3x - y + 2 = 0 Isolate y.

right answer

y = 0.2 - 0.1x or y = -0.1 x+ 0.2

y = 5 - 2.5x or y = -2.5x + 5

y = 2 - 0.4x or y = -0.4x + 2

3/5

Given the equation, isolate y.

right answer

y = 10 + 15x

y = 10 - 0.5x

y = 9.5x

Given the equation 5x + 10y = 100 Isolate y

4/5

Given the equation 5x + 10y = 100 Isolate y

right answer

if x = 8 y = 2

if x = 8 y = 10

if x = 8 y = 6

5/5
