Can anyone help me? i dont get it
algol13

Because t is the number of weeks, replace t with 6 in the equation and solve for s.

s = -0.25(6) +4

s = -1.5 +4

s = 2.5

Now replace t with multiples of 6, use 12 and 18:

s =-.25(12) +4 = 1

s-0.25(18) +4 = -0.5

now fins the difference between the time frames:

2.5 - 1 = 1.5

1 - 0.5 = 1.5

Solve 6x - 3y = 12 for y<br> A. y = 6x + 4<br> B. y = 2x - 4<br> C. y = -6x + 12<br> D. y = 2x - 12
DedPeter [7]

Answer: <em>y = 2x − 4</em>

The correct answer is <em>B)</em> <em>y = 2x − 4</em>

Step-by-step explanation:

<u>Move all terms that don't contain y to the right side and solve:</u>

<em>y = −4 + 2x</em>

<u>Then reorder −4 and 2x:</u>

<em>y = 2x − 4</em>

<u>Final answer is:</u>

<em>B) y = 2x − 4</em>

Multiply 12 by the sum of 8 and "t"
Katen [24]
Mathematically, that is 12(8+t). Distribute the 12, and you get 96 + 12t, or 12t + 96.
