Simplify:0.3(x-2y)+0.5x-y
astraxan [27]

Answer:

0.3[x-2y] + 0.5x - y


Use the distributive property: a(b-c) = ab - ac


0.3x - 0.6y + 0.5x - y


Now, add/subtract all like terms


0.3x + 0.5x - 0.6y - y


0.8x - 1.6y


If you want, we can simplify that down further to:


0.8(x - 2y)

Find the y-intercept of the line -4× - 2y =16​
Oksi-84 [34.3K]

Answer:

The y intercept is (0,-8)

Step-by-step explanation:

To find the y intercept, set x = 0 and solve for y

-4x -2y = 16

-4(0) -2y =16

-2y = 16

Divide by -2

-2y/-2 = 16/-2

y = -8

The y intercept is (0,-8)
