When 4(0.5x+2.5y-0.7x-1.3y+4) is simplified, what is the resulting expression?
padilas [110]

Answer:

-0.8x + 4.8y + 16

Step-by-step explanation:

4(0.5x+2.5y-0.7x-1.3y+4) = 4( 0.5x - 0.7x  + 2.5y - 1.3y + 4)

= 4( -0.2x  + 1.2y + 4)

= 4*(-0.2x)  + 4 *1.2y + 4*4

= -0.8x + 4.8y + 16

mojhsa [17]
Xy=12
xdy/dx + y = 12
xdy/dx = 12 - y
dy/dx= (12-y) /x
dy/dx | x=-4 ,y=-3 = (12-(-3))/(-4)
= (12+3)/-4 = -15/4

Daeja and Juana solved this equation 6 = 1/2s.
xz_007 [3.2K]

Answer:

Daeja is correct.

Step-by-step explanation:

Equation: 6 = 1/2s

Solve:

(2)6 = 1/2s(2) <== multiply both sides by 2

12 = s    or    s = 12

Therefore, Daeja is correct.

I multiplied both sides by 2 to isolate s, and 2 ⋅ 6 is 12.

Hope this helps!
