2y-x=3/4(-y+1)first distribute

2y-x=-3/4y+3/4 get the y on one side

2y-x+3/4y=3/4 add 3/4y to both sides

2y+3/4y=3/4+x add x to both sides

11/4y=3/4+x now divide by 11/4 (both sides)

y=3/11+4/11x

y=3+4x/11

choice c is the answer

Answer: $\bold{C.\quad y=\dfrac{4x+3}{11}}$

<u>Step-by-step explanation:</u>

$2y-x=\dfrac{3}{4}(-y+1)\\\\\\\text{Multiply both sides by 4 to clear the denominator:}\\4(2y-x)=3(-y+1)\\\\\text{Distribute:}\\8y-4x=-3y+3\\\\\text{Add 3y to both sides:}\\11y-4x=3\\\\\text{Add 4x to both sides:}\\11y=4x+3\\\\\text{Divide both sides by 11:}\\\\\boxed{y=\dfrac{4x+3}{11}}$

In triangle ABC, (angle A) is a right angle and (m angle B) = 45deg.

We can use the ratios for special triangles (see the attachment below). We'll be using the 45-45-90 triangle. We notice that side BC is equal to $x \sqrt{2}$ , and side AC (x using the special right triangle) is equal to 16. We can therefore say that side BC is equal to $16 \sqrt{2}$ ft
